Why do the brakes on my Car get Hot?
You changed almost everything: you also need to check the calipers and service/change them if the pistons doesn’t retract as expected, after pressing and releasing the pedal. Hot brakes means the pads/shoes are not being correctly released and they are still in contact with the disk/drum.
What does it mean when your brake system is overheating?
When this happens, you would see black dust on the wheel covers which indicates that the brakes have heated up. Another reason that already discuss is wheel bearing starting heat up. when this happened, the temperature of the entire brake system increased which made the brakes red hot, and smoke started to come out of the rotor.
Why are the brakes locking up on my Toyota Celica?
I used to have a 77 Celica that did this, and it was a problem with the front brakes. The problem would be unrelated to new calipers though. In the master cylinder as you depress the brake pedal it forces out the brake fluid to the brakes and while doing so it prevents the return of fluid back into the reservoir.

What causes brake drag in a hot car?
Heat can cause brake drag in several ways but the most common scenario is due to brake fluid reaching and exceeding its boiling point.
What are the symptoms of overheated brakes?
Another symptom of overheated brakes that I came across is when you feel a jerk up your leg when you push on the brake pedal. This happens when you are going at a high speed and hit the brakes hard. That pulsating effect is an indication of hot brakes.
What happens if you don’t cool the brake fluid?
When you apply the brakes and heat is transferred to the brake fluid, eventually the fluid will boil if the brakes aren’t allowed to cool. At first the pedal will feel spongy as air bubbles start to form in the fluid and you’ll need to push it down further to achieve the same braking power. Air is easier to compress than liquid.
