When should the brake pads on an Audi A4 be changed?
Brake pads for the 2020 Audi A4 typically last 30,000 to 70,000 miles, depending on your driving style. You should get an examination more frequently if you commute in congested traffic and apply the brakes frequently.
Is it secure to replace brake pads on your own?
To assist you with changing your own brake pads, there is a ton of information available online on do-it-yourself auto repairs. However, unless you already have auto maintenance skills, it may be more difficult than it sounds to perform tasks like changing your own brake pads or even your own oil.
If you don’t know the parts, not only can a lot of things go wrong, but you also risk missing additional serious brake concerns if you don’t know how to identify them. When you brake, you could hear grinding noises or feel your brake pedal sink quickly, but these issues could actually be the consequence of worn brake pads, a fractured rotor, or air bubbles in the braking lines. In turn, you might discover that you require more intricate repairs or parts in addition to the pads.
It’s wise to refrain from replacing your brake pads only because they frequently lead to brake issues. Before making assumptions or troubleshooting your brake pads at home, it is preferable to have an automotive expert inspect your brake system. Free thorough brake inspections are available at Firestone Complete Auto Care.
Pro Tip: Due to the extra components and connections that the front brakes lack, changing the brake shoes on vehicles with rear drum brakes can be particularly challenging. Generally speaking, it’s better to always let a qualified service professional handle front and rear brake repair.
Is it challenging to change brake pads?
You can perform some auto repair and maintenance tasks on your own, but not all of them. Should you attempt to replace your own brake pads? A DIY brake job has the following benefits and drawbacks:
DIYYou’ll Always Know When Your Brakes Need Changing
You’re probably already accustomed to the agonizing brake squeal, which is produced when metal rubs against metal. Your brake pads are worn and need to be replaced if you hear what sounds like nails on a chalkboard. This may be the most obvious indication that your brake pads need to be replaced, but it’s not the only one.
The stopping distance of your vehicle, or the distance required to bring your car to a complete stop, is another important consideration. The lengthening of the stopping distance for your car may be a sign that the brake pads need to be replaced because they are worn out.
Another clue that it’s time to change the brake pads is feeling vibrations through the brake pedal. When it’s time for a brake job, the brake pedal may even sit lower to the floor than usual, albeit this may be more difficult to notice.
Looking at them is a better approach to determine whether your brake pads will last a long time. When the friction material in your brake pads is less than 4mm thick, the majority of experts advise replacing them. To keep your car safe, your brakes should be replaced right away if the measurement is less than 3mm.
Additionally, looking at your brake pads will show you if they’re wearing unevenly, which could mean that your braking calipers need to be replaced or may be stuck.
Don’t DIYIt Can Be Tricky
Many individuals believe that reading about it online or watching a YouTube video would teach them how to replace brake pads. Although replacing brake pads is straightforward in theory, it may easily become a challenging undertaking. Your brake job could go wrong in a variety of ways, necessitating the use of extra tools or parts that you don’t currently have.
Complexity is rising in modern automobiles. For instance, if your car has an electronic parking brake, it’s frequently necessary to use an OEM-level scan tool when servicing the back brakes. And a novice or do-it-yourself mechanic wouldn’t generally have that in their toolbox. Additionally, before you can change the brake pads on a car with automatic emergency braking, you usually need to do some additional preparations.
Every automobile is unique. Therefore, before attempting to change your brake pads, make sure you refer to the manufacturer service information for your automobile. If not, you run the risk of damaging both your car and yourself.
DIYYou Can Check for Other Problems
The good news is that when you’re changing your worn brake pads, you have a great chance to examine other brake, suspension, and steering components if you know what you’re looking for. For instance, you can learn more about the operation of the brake system and check the brake calipers, brake fluid, and wheel bearings.
Don’t DIYIf You Make A Mistake, You’re Risking Your Own Safety
We’re not trying to scare you, but if you mess up changing your brakes, you can endanger your own safety. Consider this: Your brakes are essential to stopping your wheels from moving. Making a mistake when installing brakes can have major repercussions for both the safety of your vehicle and yourself.
You can be looking in the wrong place and end up doing something incredibly risky. For instance, the fasteners that hold the brake caliper and the mounting bracket for the brake caliper (if your car is equipped) must always be torqued to the proper measurement.
Don’t forget to pump your brakes many times before starting the automobile after the procedure is finished and the wheels have been replaced. Pump the brakes first with the engine off, then again with it running. The brake pedal should be pressed firmly. When you go to drive your automobile, you’ll have little to no braking capabilities if you don’t complete this stage. And that might lead to a truly miserable day.
DIYNot A Difficult Job (On Some Cars)
Replacement of the front brake pads is typically regarded as an easy, entry-level repair. However, keep in mind that you will require some instruments to complete the task. Additionally, you’ll need a space where you can work without distractions in safety. It may be worthwhile to spend money to get your worn brake pads replaced if you lack these fundamentals.
Don’t DIYCan Be Time Consuming
A set of brake pads typically has to be changed within 30 to 60 minutes. Expect to pay a professional around an hour’s worth of labor if you hire them to finish the task. It’s important to note that, as a novice, replacing your brake pads could take you up to 3 or 4 hours (perhaps even longer). Of course, everyone has to start somewhere.
DIYWider Range of Brake Pads to Choose From
The majority of individuals work very hard to increase their car’s speed but neglect to consider stopping power. Different brake pads offer various features. Additionally, if you’re changing your own brake pads, you can select the friction material that best suits your driving preferences from a variety of options.
For instance, you might prefer the extra stopping power of a semi-metallic brake pad if your car is a high-performance model. On the other hand, a ceramic brake pad will reduce wear and brake dust if you mostly drive your car in congested traffic to and from work. Finally, if you almost ever drive your car, you can probably get by with a cheap, natural brake pad and save some money.
How much does an Audi brake job cost?
Depending on the type of brake pad requested, Audi brake pads can cost anywhere between $150 per axle and $450 per axle. In extremely rare circumstances, they might even be higher if the manufacturer demands that a certain brand of brake pad be supplied for your Audi.
How durable are Audi brake pads?
Depending on your driving habits, Audi brake pads typically last between 30,000 and 70,000 kilometers. You should get an examination more frequently if you commute in congested traffic and apply the brakes frequently.
Audi Does changing brake pads require changing the rotors as well?
There are three primary brake replacement alternatives for the majority of braking systems. We’ll go through the distinctions between the three and explain why you would pick one over the other.
Brake Pad Replacement
Customers frequently run into ads for incredibly cheap brake services when comparing brake prices and services. Even while it could appear like a lucky discovery, proceed with care. This can be a sign that the auto mechanic is engaging in what the automotive sector refers to as “pad slapping A pad slap is not a thorough brake job, and it is most definitely not a long-term fix.
Together, brake rotors and pads can stop your car. The rotors eventually develop a “glaze, or a surface that has hardened, and distinctive wear patterns. You may experience braking noises, vibrations, and early pad wear since the replacement pads were maybe not formed to fit the old rotors.
Brake Pad Replacement & Rotor Resurfacing
Replacing the brake pads and resurfacing the braking rotors is a middle-of-the-road brake replacement option.
Resurfacing, also known as “turning” or “machining,” entails removing a minute layer from the rotors’ front and back faces. This gives the brake pads a nice, smooth surface to press against.
Any ridges, pits, or hotspots that could be problematic are eliminated during resurfacing. Additionally, it enables the new brake pads to wear uniformly and effectively.
But keep in mind that resurfacing reduces the rotors’ thickness. Additionally, the rotor heats up and degrades more quickly the thinner it is. Typically, rotors can only be resurfaced once or never at all before needing to be replaced.
In the end, resurfacing rotors when you install new brake pads is a decent compromise if you don’t want to spend additional money on new rotors due to its medium pricing point.
Brake Pad Replacement & Rotor Replacement
For higher stopping power and increased fade resistance, the most comprehensive brake service involves completely replacing both the brake pads and the brake rotors.
Brake rotors deteriorate over time, much like brake pads do. To be deemed safe, brake rotors must adhere to a certain thickness standard. Replace your brake rotors right away if they are thinner than the manufacturer’s suggested thickness.
Because the rotors on some vehicles cannot be resurfaced, new pads and rotors are always necessary. In actuality, this is how 99 percent of German cars are. Since their rotors are constructed of a softer metal, they are already thinner than the “discard thickness” by the time their pads wear out. This indicates that the rotor has to be completely changed because it has already exceeded the allowable minimum thickness.
However, if you’re on a limited budget, resurfacing the brake rotors can be an option as long as they are over the minimum level that is advised and the vehicle manufacturer does not mandate that the rotors be changed when new brake pads are installed.
But always prefer to change your brake rotors when replacing your brake pads for the best brake performance and safety.
Are there brake pad sensors in the Audi A4?
Electronic brake pad wear sensors have been a feature on almost every Audi for the previous 20 years. Some of them are molded into the brake pad, while the majority are mounted to the brake pad via a clip. As the wire loop is worn down and eventually breaks as the brake pads wear down, these sensors alter their electrical resistance.
The wiring for the sensors is set to the brake pad’s minimum wear requirements. Long before there is a safety issue, these sensors can alert the driver and the mechanic of the brake pads’ condition.
The model, year, and extras all affect where the brake pad sensors are located and how many sensors there are. While some Audi models only have sensors on the front brakes, others have them on both the front and rear brakes. The inboard and outboard pads of certain more expensive models, such the Q7, incorporate sensors.
Electrical resistance is a crucial element to comprehend when using these sensors, because air is the greatest level resistor. The resistance is infinite when the wire is severed. The resistance of the brake pad wear sensor system is known when it is working.
The original brake pad wear sensor circuits from the 1970s function in a similar manner to the systems used today. However, the location and method of measuring resistance values have changed. In the instrument cluster, older brake wear sensor lines were terminated. When the resistance reached 2,000 or more ohms, the circuit would activate the brake pad light and keep it on during the ignition cycle. The wear sensors on contemporary Audi vehicles are linked to a module that connects with the instrument cluster module. Even when the light is still on, the majority of systems will alert the driver to the need for brake maintenance.
Physical harm and corrosion at the connectors were the most frequent causes of failure for these types of circuits.
On the majority of current Audi vehicles, the brake pad wear sensors are wired in series for either the front or the back. The circuit is open if even one sensor is open. Finding an open and diagnosing it can be challenging due to the series arrangement. To pinpoint an issue, you must check for continuity at the connectors.
When the brake pads have the bulk of their friction material, the brake pad warning light may occasionally illuminate. This is a result of problems with the circuit’s reliability. The connectors in the wheel wells are the most likely offenders.
The wear sensor connector for the brake pads is susceptible to water intrusion, which alters the circuit’s resistance. The instrument cluster’s light turns on due to a change in resistance brought on by the oxidation of the connecting pins. The consumer may claim that the issue is sporadic, with the light ceasing to function as soon as the connector dries out during the subsequent ignition cycle. Electrical contact cleaner and dielectric grease can be used to clean and seal the connector. Vehicles with removable wear sensors that are not replaced at the same time as the brake pads are more likely to experience this.
The circuit ground is the other failing component. Locate the chassis’ ground point using the wiring schematic, then check the circuit’s continuity from there as well as the connection to the sensor.
Another typical error is failing to fasten the sensor’s wiring harness to the clips on the knuckle, strut, and control arm. The axle’s rotation and the suspension’s continual movement both have the potential to harm the wires.
These methods can assess the pad thickness if you are working on an Audi model with an electric parking brake that is either fitted with motors on the calipers or a motor that pulls the parking cables. By counting the revolutions of the electric motor, they were able to compute the thickness of the pads. However, most systems additionally include wearable sensors. In order to lessen drag, the pads are additionally retracted using the position sensor and motor.
When the vehicle is turned off, the system will run the check at a distance defined by Audi, which is normally 1,000 miles. When the automobile is parked in the garage, the customer might hear the caliper motors operating. The buyer shouldn’t be alarmed because this is common.
After replacing the rear brake pads, it is essential to use a scan tool to retract the caliper’s piston and adjust the brake pads. If you don’t do this, the brake and brake pad lights can both illuminate simultaneously.
Even if they haven’t made contact with the brake rotor, it’s always a good idea to replace removable brake pad wear sensors. The wiring and clip that holds the sensor in can become damaged over time by the heat from the brakes. When compared to a comeback, these sensors are incredibly affordable.
They are often included as part of the brake pad set with premium pads. Numerous aftermarket providers also offer these sensors.
For the driver, some brake pad wear sensor system issues can be quite annoying and sporadic. Online remedies sometimes call for removing the sensor from the wheel or from close to the connector leading to the module. Soldering wires together or grounding the wire leading to the module are classic hacking techniques. However, using these techniques disables a vital safety feature that may notify a driver of the condition of the brake pads. Since diagnosing and fixing the sensors frequently takes less time, you should make your clients’ brake systems safe.
