Brake noise. Lost all brakes while backing up

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 : 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.

ANSWER : Hi there. Were there shims installed on the old pads? New shims on the new pads? Missing shims can create noise while braking which is why the antiseize worked for a short time. What brand/level of brake pads did your husband install? Usually, the lowest priced pads are the noisiest. The antisieze that he installed is not recommended to be put on brake components as the high temperatures of these parts can cause the lubricant to run and contaminate the pads and rotors. There are specifically designed brake pad shim lubricants designed to withstand these high temperatures; these are the only ones that should be used if needed. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts and a possible safety concern. Your Mechanic has several available technicians that can assist you with a brakes are making a noise inspection.

ANSWER : Hello. The symptoms you are describing are very unusual. The clutch and brake hydraulic systems on your vehicle are separate, and should function completely independently of each other. The brake master cylinder uses a completely different set of lines than the clutch master cylinder does. I would try carefully bleeding both systems once more, just to be sure that there is no air in either system.

If both are bled properly, I would then move on to making sure that none of the components of either system are leaking. Leaks at the master or slave cylinders, or at any of the calipers or wheel cylinders will cause the systems to lose pressure. If the problem persists, I would then consider the possibility of a defective master cylinder.

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 : Hi there. First off, you have my favorite year of Corvette – the 62’ is awesome! Second, the brake squeaking issue is likely due to excessive brake dust collected in between the rotor and the pad or perhaps a wheel bearing that is starting to show early signs of normal wear and tear. It’s also possible that the pad is lightly dragging on the rotor. This can be caused by excessive brake pressure or a caliper or brake booster that is not working correctly. The best thing to do is spray off the front wheels and behind the wheel first, to knock off any excessive brake dust to see the noise goes away on it’s own. If it does not or the noise is progressively getting worse, have a professional mechanic complete a car is making a noise inspection, so they can try and replicate the noise and pinpoint it’s source, so the right repairs can be made.

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.
