1993 Acura Vigor 6 cyl Front Wheel Drive Automatic 218,372 miles. My car is locking both front brakes after a few miles. I have to wait for about 30 minutes then it will release on its own. I recently replaced my brakes and the master cylinder and it worked well for a few months then the car started to have the same problem again.
Have the master cylinder pedal free play checked, if it is tight the pressure will be applied to the brakes, as it heats up the pressure will increase, and releasing as it cools down. Check pedal free play first and if there still is a problem re post for more checks.
