I took the car to more than one place and no one wants to even check whats wrong with my brakes because the car is modified WTF I did change the front rotors, calipers and pads and nothing changed. Then i changed the Brake Booster and still nothing changed. The brakes works fine when the car is cold, but after the brakes warms up it starts holding slightly and it doesnt fully release which is really annoying. The pedal feel also change when this happens and it gets really stiff with almost no travel. My gas milage dropped to half and driving the car is a hassle now. What could be wrong with my brake system?

 

Sounds like a stuck caliper guide pin or a stuck piston.
