New brake pads installed, when the car heats up the brakes squeal?

Hello FRANKY SILVIA,

The first thing I would do is check your brake fluid level. A low brake fluid level will cause the light to come on. It's possible your vehicle may be leaking fluid on the brakes making them squeal.

Squealing can also be caused by cheap brake pads and/or rotors, too much heat, rust and others but it would happen all the time if that were the case.

I would start by checking your brake fluid and looking at the back of your wheels for any signs of a leak. Also make sure your emergency brake isn't engaged as this will cause a brake warning light as well.

Check the brake rotors, calipers, hoses and I would also look around the inside of the rims. If they are leaking brake fluid could be on the inside of the rim from being thrown off the rotor from centrifugal force as the vehicle moves.

**A red brake light could indicate a serious issue with your brakes and the vehicle should not be driven until the cause is figured out. For your safety as well as others**

If it is leaking, you will eventually lose all fluid and have almost no brakes if any.

Is it pulling to one side at all?
Loss of braking power? For instance, more effort is needed to slow down the vehicle. Especially after driving?
Pedal spongy or going to the floor?
Any funny smells from wheels or smoke?

Also did you have any other work done when the brakes were done or pads and rotors only?

Non-the-less, I wanted to share this article with you. It will give you some basic information on brake squealing and possible causes:

This is a good article to give you some information on figuring out why the brake warning light is on:

If your brake fluid is low, you can add some more. Your vehicle takes DOT 3 or DOT 4. It should say it right on the cap of the master cylinder. I will add a picture of a typical brake master cylinder for your information. Make sure you buy a new bottle though. Brake fluid attracts moisture and an open bottle of brake fluid that has been sitting around will collect moisture and cause the moisture to turn to a gas in your braking system, which is compressible unlike a fluid. So, using a new bottle of fluid is a must.

I have added a couple of examples of brake fluid leaks as well as a bottle of brake fluid of the kind I use on my own vehicles.

Let me know what you find. Brake squealing is not uncommon at all but since it's happening after the vehicle has been driving for a while and the red brake light is on is a little concerning to me.

Thank you,
Brendon
