1962 Ford Falcon. I adjusted the brakes (drums all round, with power booster) and now i frequently get the brake pedal going almost to the floor before working. Master cylinder or wheel cylinders need a kit, or something else?
If there are no leaks, then I would first suspect that the shoes are not adjusted close enough to the drums.
This then means all the pistons have to move too much which demands more volume of fluid and then the pedal has to travel further.
So, re-check the brake shoe adjustment.
I agree. If, however, the pedal still feels soft when the brakes begin to work, I'd suspect the master cylinder is failing. Mar 11, 2021 at 15:54
