My brakes are making noise

My breaks make noise

My car has 50000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
When brakes become noisey it can be due to the pads are worn out and the brake wear sensors are scraping on the rotors. The noise could also be due to material in the brake pads or rust on the rotors causing the noise. The brake noise should be inspected to see what is causing the problem and to see if there is any safety related issues with the brakes.

Common reasons for this to happen:

Excessive Pad Wear: The single most common reason to hear a grinding noise when braking is excessive pad wear. Once the material has been worn off the backing plate, you`ll be experiencing “metal on metal”. Part of the brake caliper could also be touching the rotor at this point.

Sometimes, new brake pads need to be broken in. Other factors that can contribute to squeaky brakes include dirt and debris on a brake pad, a damaged brake pad backing plate, a bad brake shoe, or weak brake shoe return springs. With so many possible causes, a squeaking or squealing noise can be difficult to diagnose.
Worn or thinning brake pads

– When your brake pads are worn and new pads are required, you will hear a high-pitched warning sound from your front brakes or rear brakes (if equipped). You may hear this sound come and go, or it may occur whenever you depress the brake pedal.

One possible cause is debris or dirt stuck in the brakes, which can create friction and lead to a grinding noise. Another potential reason is a misalignment of the brake calipers, causing them to rub against the rotor instead of smoothly pressing against it.
If you hear grinding noises when stopping or slowing down, your brake pads are most likely the issue. Remember, over time your brake pads lose their thickness and begin to make squealing noises known as “brake scrubbing.” As your pads wear down further, you`ll hear a grinding noise instead.

when i turn it make little noise. when press on brake and put on reverse it’s makes weird noise and shakes. thank you
ANSWER : It sounds like you may be dealing with a few issues. I would start by asking if there is a check engine light on? If there is, then getting the engine control module scanned for faults would be the first step to diagnosing the low power issue. As far as the noise over bumps and when turning, there could be a damaged CV joint or axle shaft, or there could be a loose suspension or steering component. Weak motor mounts could cause a weird noise and shake when going into reverse with your foot on the brake, so it’s possible those have failed as well. I would suggest having a qualified mechanic, such as one from YourMechanic, diagnose the noise over bumps and the noise when put in reverse.

My car makes a grating noise while applying the brakes to turn
ANSWER : It sounds like you need to check your front brakes. Most of the braking is done with the front brakes, therefore they tend to wear out more quickly than the rear brakes. If you let it go too long, you will need to replace the rotors as well. Have the brakes checked ASAP as this is also a safety concern for you and others on the road. I suggest having a certified technician, like one from YourMechanic, inspect your braking system to determine the exact cause of your concern.

Low brake pedal and anti-lock brakes are not kicking in.
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.

When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
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.

EPC light on 2004 Jetta. Code said brake switch faulty, but brakes lights worked. Replaced brake switch, now no brake lights.
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.

Rotors and brakes were replaced only 6 months ago, but have now been making noise again for 3 months.
ANSWER : Hi there. Brake squeaks and squeals are a result of pad vibration, unless it’s a sensor touching letting you know it’s time for brake pad replacement. All brake pads vibrate, whether it’s audible depends on the frequency at which the pad(s) vibrates. This audible vibration may be the result of loose pad hardware or poor fitting replacement brake pads. I recommend having your vehicle’s brakes noise diagnosed and repaired by a certified technician, such as one from YourMechanic.

Brakes are making squeaking noise – 1980 Toyota Cressida
ANSWER : Brake noise or chatter occurs when the brake pad backings vibrate in the pad guides and caliper housing. Often the application of a brake grease or anti-seize lubricant can be applied to the contact point of the brake pad backings and this will absorb and dampen the pad pulsations which are breathing the noise. You may want to enlist the help of a mechanic, such as one from YourMechanic, who has the tools and expertise to inspect and correct noise issues in the braking system.
