Why do my brakes lock up when they get hot?
The push rod may be pushing on the master cylinder a little bit. This could cause the brakes to not fully release. After driving the brake fluid starts to heat up and expand putting even more pressure on the brakes until they overheat and lock up.

What are symptoms of a bad master cylinder?
When a master cylinder begins to fail, sometimes the brakes will feel fine one second and lose braking power the next. If fluid is leaking past the seals inside the cylinder, the pedal may feel firm for a moment but won’t hold steady; it’ll feel spongy and keep sinking towards the floor.
Can a brake booster cause brakes to lock up?
But if the booster is getting stuck in its boost mode, it will continue to apply force to the brakes, even after you release the pedal. Then, the next time your brakes lock up, pull over and disconnect that vacuum hose. If the brakes free up, bingo – you need a booster. But it could be a master cylinder, too.
Can a bad ABS sensor cause brakes to lock up?

Where does friction occur in the braking system?
When you use the braking system, there are two general points of contact that create friction between each other. The first one is inside of the braking system. This is where the individual components of the brakes will come in contact in order to slow down and stop the vehicle. The second point of contact is between the actual tires and the road.
