Hi muddiger,

If both the front brakes are sticking after some driving, you need to check the master cylinder push rod clearance and also the clearance between the brake pedal and booster.

If there are insufficient clearance, the master cylinder piston would not return fully to allow pressure to be released when the brake pedal is not depressed.

If equipped with ABS, the modulator should be checked.
