Reply to "Brakes locking up"

You are looking in the wrong direction. The pushrod is behind the adapter plate that is attached to the booster. The pushrod presses on an adapter piece in the center of the adapter plate.


What you want to do is slowly move the master up to the front of the adapter plate and see if the piece inside the adapter contacts the back of the master piston (the green part) before the flange of the master contacts the adapter plate. You do this by feel because you cannot see the parts making contact. If the master piston moves you can feel the resistance. When you take the adapter plate off to adjust the push rod be careful not to damage the rubber donut seal on the booster.

You can also measure the two distances to see if there is a gap.
