A bracket at the very top, behind the brake pedal arm, holds the brake light switch on a Toyota Corolla. It is a tiny switch that resembles a button. The circuit is closed when the button is extended, and when it is pressed in, as when the pedal is let go, the circuit is open and no current is flowing.

Step 1
Examine the brake pedal stopper bracket that is attached to the top of the pedal arm. To turn off the brake lights, this bracket makes contact with the switch button. This bracket has issues in several Toyota automobiles. The switch button’s wear is prevented by a rubber stopper in the bracket. Sadly, the plug frequently comes loose. When this occurs, the brake light is kept on because the brake light switch button is not fully depressed when the pedal is released.
Step 2
Light your way to the bracket with a flashlight. There are two options if the plug is missing: either replace the plug, or glue a penny over the hole. The penny trick works well even though the plug can only be found at the dealer.
Step 3
Use a Phillips-head screwdriver to remove the lower dash filler panel for easy access to the brake light switch. Depending on the year of the car and the size of the person performing the service, this is not always essential. There is no need to remove the cover if you can lie on your back and reach under the dash, but do so if necessary.
Step 4
The brake light switch’s electrical plug should be removed. By using a wrench to loosen the nut close to the electrical connector, you can remove the switch. Pull the switch out after rotating the nut off the switch’s button side.
Step 5
Installing the nut on the button side of the switch after pushing the replacement switch into the bracket’s hole. By turning the nut nearest to the button, you can adjust the switch such that the button is sufficiently depressed by the brake pedal arm. Release the pedal after a brief push. The switch shouldn’t prohibit the pedal arm from coming to rest. The button should only be pressed by the arm. Apply a wrench to the rear nut to lock it down.

Is changing a brake light switch simple?
severe, since it’s in your best interest to make sure the automobiles in traffic behind you are alerted to your slowing down. Additionally, your cruise control won’t operate properly if your brake light switch is damaged. A faulty switch won’t cause the cruise control to turn off if the brake lights come on. Fortunately, this is a fairly simple, anxiety-free repair.
The switch is conveniently placed just next to the brake pedal, next to the ball of your right foot. It’s possible that the switch can be installed without using any tools at all. Most autos should have labor costs of $20 to $50. The lower dashboard of some luxury vehicles might need to be disassembled, which could cost $100 or more.
What signs might point to a broken brake light switch?
Although brake light switches are made to last as long as your car, they could eventually get broken. If you experience any of these signs, think about changing the broken brake light switch:
Your Brake Lights Don’t Light Up
When you depress the brake pedal, your brake lights should illuminate to alert the driver in front of you.
The back brake lights won’t turn on if your brake switch isn’t working properly, which presents a serious safety risk because the vehicle behind you won’t be aware that you’re slowing down.
Now, this can mean that a brake light bulb in the back has burned out or that your brake light switch is broken. Consider having your car inspected by a mechanic to swiftly identify the problem.
BrakeLights Stay On Continuously
There may be a fault in the electrical circuit inside the rear brake light switch if your brake lights remain on even when you are not pressing the brake pedal.
Drivers behind you may become confused if your brake lights are constantly on even if you may be driving properly since your taillight suggests that you are about to slow down.
Additionally, if your rear brake light is left on all the time, it can quickly drain your car’s battery and harm the brake lamp or bulb.
It’s best to call a repair right away to replace the brake light switch if you have a problem with your brake lights so that no other electrical components are harmed.
Bad Cruise Control
If your car has cruise control, a broken or misaligned brake light switch can turn it off.
The switch for the cruise control and the rear brake lights is frequently shared. Therefore, if the brake lamp switch fails, your cruise control will probably too.
This does not imply that the brake light switch issue is the only reason the cruise control malfunctions. A blown fuse in the electronic control module or a malfunctioning speed sensor might also cause it to occur.
Therefore, get your brake light switch checked by a repair as well when your cruise control is acting up.
Car Won’t Turn On
All you have to do in these cars is depress the brake pedal to start the engine.
If the brake light switch isn’t communicating a precise signal to the vehicle’s computer confirming that the brakes are applied, your car may not start.
When this occurs, contact a mechanic or auto repair agency right away to have your brake light switch replaced.
Where is the switch for the brake lights?
A little gadget connected to the brake pedal mechanism is called a brake light switch. The brake light switch, despite its diminutive size, has a significant function in contemporary automobiles.
If a brake light switch is malfunctioning, many vehicle functions, such as Push-Button Start, Antilock Brakes, and Vehicle Stability Control, will not function.
There are two main purposes for the brake light switch. When a driver depresses the brake pedal, it first activates the brake lights. Second, it informs the car’s computer that the brakes are being used. Driving a car with a broken brake light switch is VERY RISKY.
The brake light switch is typically located just over the brake pedal. It has a one-way or two-way electric switch within. Brake lights that don’t turn on or that stay on all the time are the most typical signs of a broken brake light switch.
Why do my Toyota Corolla’s brake lights not go off?
Bad Switch: A faulty or failed switch is a typical cause of the Parking Brake light remaining on. You may quickly verify this by jiggling the handle once it has been lowered. The switch is most likely to be the problem and needs to be replaced if the light goes out (or goes out and comes back on).
If the brake handle is not fully down, there is another factor that could cause the light to remain on. Verify again that the parking brake is released and that the handle is fully lowered. The light will remain on if the parking brake cable is under any stress.
Parking Brake Not Disengaging: Occasionally, the parking brake itself is the source of the issue rather than the switch or the wires. The dash warning light will remain on if the brake does not release when the handle is dropped.
Low Brake Fluid: Your Parking Brake light is a multipurpose device that is intended to turn on when the reservoir’s fluid level falls below a specific level. As the fluid level fluctuates, you might see the light turning on or off when making turns.
The brake fluid level sensor in your master cylinder is malfunctioning. It is sometimes integrated into the reservoir cap, and other times it is positioned on the side of the sensor. The Parking Brake light will come on if the sensor malfunctions or becomes faulty.
Uneven Fluid Pressure: If your automobile has uneven brake fluid pressure in one or more lines, it may influence how well it can stop and may even cause it to pull to one side or the other. The parking brake light in your dash can also be activated by it.
Is AutoZone a brake light switch replacement shop?
Problems with the brake light switch or turn signals A replacement switch can be placed after you check the connection to the switch for corrosion or other problems and buy it at your neighborhood AutoZone.
How much does a new brake light switch cost?
How Much Does a Brake Light Switch Replacement Cost? Depending on the make and model of the car, a replacement brake light switch typically ranges in price from $30 to $75. The cost of the repair will normally increase by $80 if the brake light switch needs to be repaired. You can perform a brake fluid replacement on your own.
Are brake lights battery draining?
The brake pedal, striker, brake light switch, lights, fuses, and wiring are just a few of the components that make up your brake system as it relates to your lights. The attached brake light switch makes touch with the pedal when you depress it, allowing the brake lights to turn on.
Through the electrical components, this switch informs your brake lights that the pedal has been depressed. When you take your foot off the brake pedal, the striker releases the brake light switch, turning off the brake lights. Despite the fact that this is a condensed explanation of how brake lights function, damage to the striker or brake light switch may result in brake light problems.
a word of advice: Leaving your brake lights on while your car is stationary will drain the battery. To prevent your battery from being drained, it’s critical to quickly fix brake light problems.
How can I test the switch for my brake lights?
You’ve checked the brake light fuse and the brake light bulbs, but the power to those areas is still not working. You should in this case examine the brake light switch. It is a device that joins and completes the electrical circuit for the brake lights in a car. It’s a relatively straightforward two-wire switch, with one wire controlling power coming in and the other controlling power leaving.
The switch, which is close to the brake pedal, is probably marked. Get your test light out once more, and ground it just like you did when you examined the fuses. Place the sensor on just one of the two wires while maintaining a firm grip on the brake pedal. Next, examine the other wire. The test lamps will light up if the switch is functioning properly and the power is connected. The brake light switch needs to be replaced if it doesn’t illuminate. Use the owner’s manual to find the major “power in” and “power out” lines if your switch has a more intricate design with more than two wires. Then, test those wires.
If you try all of these solutions and your brake lights still don’t function, there may be other systems in your car that require inspection. For instance, if your car’s turn signals and brake lights are wired together, you’ll need to check those systems’ fuses. Modern automobiles come equipped with an exclusive “brake light control module,” an integrated computer system, and onboard diagnostic scans to identify any issues.
Generally speaking, repairing a car’s brake lights is simple, but there are times when you should seek the advice of a qualified mechanic. It’s crucial to get those lights fixed as quickly as possible, whatever your car needs.
Can a bad switch for the brake lights drain the battery?
Brake lights that stay on at all times are one of the signs that a brake light switch is broken. The brake lights may continue to illuminate even when the brake pedal is not depressed if the brake light switch internally shorts. As a result, the brake lights will burn out earlier than they should and the battery may experience parasitic drain.
Can a defective brake light switch turn on the ABS light?
On the other side, a defective brake light switch can result in the failure of the lights. You might still want to inspect this crucial component if it isn’t operating at all.
The lights won’t turn on if the switch doesn’t detect your foot movement on the pedal. When other drivers are unsure of whether you are braking, this creates an on-road danger.
Gear Selector Can’t Be Moved
You must have your foot on the brake pedal in order to shift the gear selector out of Park. You might not be able to move the shifter into a different position if the system isn’t understanding your command.
Unfortunately, this situation leaves you stuck in your current location. You can resume driving if you can change the switch at the current position.
Illuminated Dashboard Warning Lights
Multiple dashboard lights may illuminate when the brake light switch malfunctions since it is a component of numerous systems. The Traction Control or ABS lights are the most frequent indicators.
However, the Check Engine Light can also be seen. This generally only appears when the brake switch is causing you difficulties starting the car. Any lighted light needs to be taken carefully and examined straight away.
Why do my tail lights function, but my brake lights do not?
A broken light bulb is the most frequent cause of brake lights that don’t work yet taillights that do. A busted fuse, a defective brake light switch, or problems with the wiring can also be to blame.
While the brake lights on your car should illuminate when you use the brakes, they don’t. Given that both lights’ connections effectively come from the same source, this is a peculiar issue. When you apply the brakes, either one light flashes more than the other or the taillights entirely turn off.
There is a cause for every problem, and every problem has a remedy. Why your brake light doesn’t function yet your taillights do is explained in more detail below:
Bad Light Bulbs
LED taillights are a popular choice for modern automobiles. However, if your car is older, you should inspect the lightbulbs.
Although they frequently have the same bulb, the brake light and tail light have two distinct circuits. As a result, it’s possible that one circuit is working while the other is damaged or burned.
The process of replacing light bulbs is frequently extremely simple, and they are relatively inexpensive. However, you can test them with an external 12 volt source or measure them with a multimeter to make sure they are not dead.
It’s highly uncommon that all three brake light bulbs will fail at once, although it is possible if you’ve been driving for a while without noticing. If the incorrect fuse is put, there might also have been a circuit short someplace that blew all the lights.
There is a good probability that it is merely two blown bulbs, particularly if two of your brake lights are malfunctioning but the third brake light is functioning.
Bad Brake Light Switch
When your brake lights stop working, a bad brake switch is a common issue. Your brake pedal has a tiny switch inserted to let the control unit know when the pedal is depressed, which turns on the brake lights.
A multimeter can be used to test the brake light switch to ensure that there is no connection when the switch is depressed and a connection when it is released. Depending on the brake switch type, this could also be the other way around.
Broken Fuse Or Fuse Box
Electricity is delivered to every piece of electronic equipment in a car via wires that pass through a fuse box. Several fuse boxes are present in modern autos. Both one under the hood and one below the dashboard are common.
Find the location of the brake light fuse in the owner’s manual for your car. The likelihood that the brake light fuse has blown off as a result of an electrical surge is considerable. Find the appropriate fuse, then swap it out for one that is comparable.
Most of the time, a fuse blows for a cause. Make that there is no circuit short on the wire or in the connector to the brake light if the fuse has blown. They can, however, blow occasionally due to aging.
Keep in mind to simultaneously inspect the fuse box for any water stains, as these might lead to circuit shorts in the fuse box and perhaps blow a fuse.
Bad Sockets and Connectors
Additionally, the connector pins for the taillights may be corroded. Inspect the tail light connectors for any corrosion or rust by removing them. Reinstall them after giving them an electrical cleaning.
Additionally, see whether there is a connector plug in the vehicle that runs from the brake light switch to the taillight. Sometimes a plug on the floor of the automobile has been filled with water, which has caused corrosion.
Additionally, there is a risk that the sockets where the light bulbs are installed have rust or corrosion. Check it for rust and use an electronic spray to clean it.
Broken Wire
Rarely, there might also be a wire that is broken. Finding this can be quite difficult because the wiring from the brake light system may go from the front to the back of the vehicle.
When you press the brake pedal and do the same at the brake pedal switch, you may measure the voltage at the taillight. A blown fuse or a damaged wire in the power supply is to blame if none of the wires leading to the brake light switch have electricity.
