With an electric handbrake, how do you change the rear brake pads?
Brake Pad Replacement Using an Electric Parking Brake
- Connect a battery charger for cars.
- Join a diagnostic device.
- Parking brake pistons should be loosened.
- Push the pistons and remove the caliper.
- Change the brake pads.
- Install Caliper again.
- Expel the pistons.
- Parking brake pistons are reengaged.
With the parking brake engaged, can brake pads be changed?
Electric parking brake systems come in two different categories:
- Electric motor: This electric parking brake system is a feature of various GM automobiles. Similar to a conventional parking brake system, but with a motor pulling the cord instead of a person’s hand or foot. A parking brake control module is the name of the motor. Once engaged, it uses the parking brake wire to pull the parking brake shoes.
- Parking brake actuator: Vehicles with an electronic parking brake system that are not GM can have this system. Parking brake actuators are fixed to both rear brake calipers. A gear that has the ability to drive out the caliper piston is connected to each parking brake actuator. The parking brake actuator has the ability to shift that gear when engaged. The brake pads are pushed up against the rotor by the piston as a result. To put it another way, when this system is engaged, the rear brake pads can serve as the parking brake.
When an automobile is put into park, the parking brake is often activated automatically, even if the driver doesn’t press the parking brake switch. You must first turn off the electric parking brake in order to replace the brake pads on the rear brakes.
Does the electronic parking brake release on its own?
When the typical handbrake lever is pressed up, a cable is tensioned. This cable applies pressure to the braking drums or discs in the rear of the vehicle, holding it securely in place. On the back axle of some vehicles, there may be a special disc and pads.
The basic idea is the same regardless of the technology a car employs: pressing the lever locks the back wheels to prevent the car from moving when you don’t want it to.
Electronic parking brakes, often known as electronic handbrakes, operate on the same principles but employ electric motors to produce the locking effect.
The rear brakes’ motors force the brake pads against the discs when the button is pushed or pulled. The motors frequently provide a comforting humming sound as they operate.
Most electronic handbrakes release themselves when you start moving. When you press the accelerator and raise the clutch past the point of biting in a manual transmission vehicle, the clutch will release.
The amount of throttle input’ an automobile needs to release the handbrake, however, is not standardized in the industry. Some need only a light touch of the accelerator to release, while others require quite a few revs.
Driving a manual car with an electronic handbrake can be challenging as a result. The tensing of the automobile at bite can seem rather noticeable, and the release can be quite harsh.
As you become used to it, don’t worry too much if you start to stall. It quickly becomes automatic.
Can I simply swap out the rear brake pads?
Brake repair is one of those things that needs to be done right away for your car.
Each year, brake failure contributes to 300,000 accidents in the US. Avoid putting your loved ones or yourself in needless danger.
One technique to make sure your car remains safe on the road is to change the brake pads. But how can you tell when to change your brake pads? Do you think you should change all four at once?
What Do Brake Pads Do?
You already know that a vehicle’s brakes must work properly, but do you know exactly what brake pads are and what they perform?
The most crucial component of your car’s braking system is actually the brake pads. Your brakes’ pads are the component that makes contact with, exerts pressure on, and creates friction with the brake rotors to stop your car.
The flat, gleaming discs that are typically found behind the wheels of cars are the braking rotors. Your car’s wheels each have their own set of brake rotors and pads.
The brake pad degrades with time as a result of the ongoing friction between these two components. When you need to stop your car the most, the less traction it has, the less effective it is.
Do You Need to Replace All Four Brake Pads at Once?
Do you have to replace all four brake pads at once even though the majority of brake pads are sold in bundles of four?
The front and rear brakes and rotors are paired together, so keep that in mind initially. You have the option of replacing the front and rear brake pads in pairs at the same time or one pair at a time. Your mechanic can take care of this problem on their own if your front brake pads need to be repaired or replaced.
You should also be aware that the front and rear brake pads on your car wear out at quite different rates. The majority of the work is done by the front brake pads, which accelerates wear and increases replacement frequency.
Your automobile lurches forward as you apply the brakes, coming down directly on the front wheels. The majority of your car’s braking power originates from this.
Additionally, by relieving pressure from the back tires and brake pads, this movement increases the amount of friction between the front tires and the ground. Most automakers base their vehicle designs on these fundamental ideas. Your car’s front brake pads are designed and manufactured to withstand the shock, pressure, and friction of vigorous braking.
Brake Light Will Come On
Those obnoxious tiny lights that flash on our dashboards are something we’ve all experienced. These lights aren’t always something to ignore, though.
When the service light on your dashboard illuminates, you can be certain that your brakes need to be repaired. This indicator is often red or yellow and may also have the words “brake” or “anti-lock brake” along with the exclamation point sign in brackets (!)
Additionally, make sure your parking brake wasn’t accidently engaged. If you did, your dashboard would flash with the letter “P.” Turning off the parking brake should extinguish the light. If you get this indication, it can just be a false alarm and your brake pads are fine.
Because some older automobiles don’t have illuminated dashboards, you’ll need to find another technique to pinpoint the issue.
Failed Inspection
Your brake pads may be found to be thinner than allowed if the state where you live mandates an inspection. Some experts can also conduct a visual examination to see whether your brake pads need to be replaced or repaired if they are worn out.
The sound of your brakes squeaking, screeching, or grinding is another indication that the thickness of your pads is wearing down. This is the metal from where the brake pads previously rubbed on the rotors’ metal. If you wait too long, you might also need new rotors.
A Vibrating or Shaking Steering Wheel
Your steering wheel may shake or tremble when your brake pads are wearing thin or your rotor is uneven.
Your rotors should be smooth and able to make touch with the brake pads while performing properly. However, wheels may rotate unevenly, which can result in flaws in your rotors.
As the wheel spins, friction is produced between your brake pad and an uneven rotor. This may cause a bump by wearing down the pad or transferring some of the force to your rotor.
Your brake pad is contacting these rotor flaws as you brake and experience shaking or wobbling. Your vehicle may also start to pull to one side. This may occasionally be due to a problem with your steering or suspension system (such as your wheel alignments), but it may also be due to your brakes needing maintenance or repair.
Change in Brake Pressure
When you step on the brake pedal, it should feel somewhat resistant. If you apply the brakes and feel less (or more) resistance, your car may need brake repair right away.
Some individuals call this sensation “soft,” “sinking,” or “squishy.” This alteration could be the result of brake fluid leakage, trapped air or moisture, or both. It might possibly be a problem with the master cylinder, in which case a mechanic should be called right away.
Perform Routine Brake Repair and Stay Safe
When it comes to brake repair, there is no room for error. You should take your car to the shop right away if it exhibits any symptoms of worn brake pads, rotors, or other brake-related problems.
Give a skilled mechanic a list of the red flags you’ve seen so they can identify the issue. You, your passengers, and other drivers will stay safe if your brakes are working correctly.
Regular vehicle maintenance performed by a mechanic can stop problems before they start.
When changing pads, do the brakes need to be bled?
Your braking system is the most important one in terms of essential parts. You must be able to stop at any time, no matter how quickly you’re moving. Hydraulic braking systems for vehicles operate by pushing pressurized fluid. There will be less pressure, spongy-feeling brakes, and lengthier stops if there is an air bubble in the system. But that’s only the start. The car might not stop at all if left unattended.
There is a technique to avoid this in addition to fixing it. Let’s examine when and how brakes should be bled.
When to Bleed Your Brakes
First off, you aren’t truly bleeding brakes; rather, you are removing air bubbles that may have developed prior to pouring fresh brake fluid by bleeding fluid and air out of the braking system.
When should you bleed your brakes?
- when the brakes begin to feel soft.
- when pauses take longer and you start to lose confidence.
- if you discover a leak Air may also be let in through leaks in addition to fluid. Bleeding your brakes after fixing the leak is the only way to ensure that your system isn’t affected by an air bubble.
- if you’re changing out worn-out brake pads, as this could lead to air getting into the master cylinder. More brake fluid is needed while braking with worn brake pads, which empties the reservoir and leaves room for air.
- if you replace your brake pads or rotors. For the purpose of safety, every brake job needs to include a brake bleed.
- As part of good preventive maintenance, once a year.
How to Bleed Your Brakes
You’ll need a screwdriver for Torx screws (detectable by the six-pointed groove on their heads), as much fresh brake fluid your car needs, and a container to catch the used fluid for all four methods of bleeding brakes.
Here are the four techniques for bleeding brakes:
- Put a container underneath the bleeder screw, turn the screw to let the old fluid fall into the container by gravity. Afterward, there will be cleanup. The liquid won’t fall in a straight line; instead, it will drip down components in the space between the container and the bleeder screw.
- By hand: Place a container beneath the bleeder screw and open it as someone gently presses and releases the brake pedal, forcing the fluid and air out of the system. Smoothly use the brakes to prevent the formation of further air bubbles that could linger and contaminate the fresh fluid. Make sure the fluid isn’t frothy, as that indicates that new air bubbles are beginning to form.
- Once more, place a container under the bleeder screw and open it to provide pressure. The fluid and air should then be forced through the system and into the container using a tank of pressurized braking fluid at the master cylinder.
- Vacuum: For this technique, when you open the bleeder screw, fasten a vacuum bleeder to it. It extracts the liquid and air into a connected container.
Regardless of the route you take, bleeding your brakes when there is a problem or as part of routine maintenance ensures that your braking system operates as effectively as possible and keeps you and your passengers safe.

How long does it take to replace the brake pads on the back?
Consider this: even a skilled automotive technician needs at least an hour to replace the braking rotors and pads on some cars. Brake pad repair could take several hours or longer for a person with little to no skill.
Learning the procedure, assembling the necessary supplies, carefully carrying out each step, and then putting everything back together again might easily take up a half-day of effort that may not be worthwhile in the end.
You might need to start over to fix the issue and correctly install the new brake pads if you complete the procedure only to discover that the brake pedal feels strange or that your brakes have begun to screech or grind. What a pain in the neck!
An easy approach that might ultimately save you time and money is to have a professional do your brake pad repair.
How is a brake caliper reset?
One of the chores you must complete while installing new brake pads or before bleeding the braking system is resetting the pistons in your brake caliper.
To demonstrate the difference, a photo of a Shimano Deore M596 brake caliper before and after the pistons were adjusted is provided below.
Your caliper pistons can be repositioned in one of two methods. The easiest way is with the brake pads in situ. To turn, merely insert a flat-bladed screwdriver between the brake pads. As a result, the brake pads will disengage, pushing the pistons back into their reset position.
Instead of going through the hassle of reinstalling your brake pads if you’ve already taken them out, grab a plastic tire lever and use it to push the pistons back into their housings.
Resetting the position of the pistons should never be done with sharp or metal tools as this could lead to harm.
After readjusting the caliper piston positions, you can now install your new brake pads or bleed block.
Why can’t my brake caliper be compressed?
You might be dealing with a caliper piston that won’t compress if you’re having difficulties adjusting your car’s brakes or if the automobile is dragging to one side and wearing down the brake pads. What led to this circumstance, and what can you do to change it?
If the caliper piston won’t compress, it’s probably because of a corroded or rusted caliper piston that was brought on by a defective piston boot. Consider the possibility that the incorrect wind back process is being performed if the problem is with the rear caliper piston.
