Brakes

Postby rreems » Wed Dec 13, 2017 7:52 pm

Hi all. I own a 1968 4 door moggie and i’ve Rebuilt the master cyl, replaced all wheel cylinders and brake shoes adjusted and bled the system when I brake the pedal is firm but then it travels a bit more and a bit more when stopped! Any advice would be welcomed
Thanks
Richard

How old are the rubber flexible pipes? They may be soft and expanding slightly.

If the pedal continues to travel once the car has stopped it is generally a master cylinder problem.
Replacing the flexible hoses will do no harm though if that hasn't been done already.

Seems like fluid is passing the seals in the mater cylinder. Possibly a damaged seal lip at rebuild, master cylinder worn excessively, poor quality seals or even a porous patch on the surface of the cylinder. Needs sorting urgently, before it becomes a catastrophic failure (no brakes at speed!).

While flexibles might well be benefit from a change, if not already done, that will not give these symptoms.!

From your fault description above I would advise that the Master cylinder is replaced.
Use a good quality master cylinder though.
