Should there be free play at the Master Cylinder push rod?
Ans. There must be free play on the push rod of the master cylinder. If there is no free play, the piston in the cylinder will not return to its home position, therefore causing the brake system to be engaged at all times. Each time you push on the brake pedal it puts a little more pressure on the system, which will cause the brakes to drag, get hot and eventually lock up. Check to see if the return spring is pulling the brake pedal to its home position thus not allowing the internal Master Cylinder spring to do all the work. 9.
