Brake pad noise

ANSWER : It sounds like you may have a weak ABS wheel sensor and a loose wheel bearing. When you hit the brakes, the sensor losing signal may be causing the ABS to activate. You would need to have the ABS diagnosed to see what sensor is having the problem and to check that wheel bearing and sensor. You may have to replace the bearing and have a sensor replaced in this case. I would have a certified technician, such as one from YourMechanic, inspect the noise in person before moving forward with a repair.

ANSWER : The brake pedal is working to stop the vehicle, but there may be air in the controller unit causing the ABS brakes to not function. I recommend bleeding the brake system from the farthest location from the master cylinder to the master cylinder including the ABS unit. If the brakes are still spongy after a full bleed, then the controller will need to be replaced. If you need further assistance with your brake pedal being spongy, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.

ANSWER : Hey there. If the noise was not there before you replaced the brake pads on your 2014 Audi A4, you might want to try replacing the caliper clips and using a good quality brake lube anywhere the pads make contact with the caliper, caliper piston, and or bracket. If you need to have this looked at, an expert from YourMechanic can come to your car’s location to diagnose the squealing noise and perform the appropriate repair.

ANSWER : It’s possible to have someone alter the brake pedal or adapt a brake pedal from a different vehicle. You may call around to some customization shops to see if anyone is interested in taking on the project. But first, I would try reaching out to the selling dealer with your concern – especially since it is a new model. Good luck.

ANSWER : Hello, thank you for writing in. The last technicians that worked on your vehicle are not wrong. There are certain types of brake pads that will make a squealing noise when the brakes are applied. These are typically made from a metal composite material. You can always research the brand they put on and find out more about the brake pads. This would give you a good idea of what you should reasonably expect. Are the brakes exhibiting any other types of symptoms? If there is any sponginess in the pedal, shaking or vibrating, hard stops, or other symptoms then there may be more cause for concern. In situations like these, if you are expecting to drive the vehicle a longer distance in the near future, it is recommended that you get a second opinion. Our technicians can dispatch to your home or office.

ANSWER : Hi there. The first thing that pops in my mind beyond of what you have listed is perhaps the electrical harness attached to the brake switch. Perhaps the harness itself is damaged or you have an exposed wire, loose ground wire somewhere. You might want to have a professional mobile mechanic come to your location and complete a brake lights not working inspection to help you diagnose this issue.

ANSWER : After seeing the video, you will need to have the lower ball joints and bushings checked to see if one or all need to be replaced. You should also have the exhaust checked to see why the engine is so loud. A professional mechanic, such as one from YourMechanic, will be able to thoroughly conduct tests to diagnose your vehicle’s popping noise and make the appropriate repairs.
