After totally overhauling the front and rear brakes, I was able to successfully bleed the rear brake circuit and the rear brakes work well. The front brakes are a diffent story - despite bleeding out the air, no brake pressure is generated to operate the pistons.
I have the original Girling tandem master cylinder type 68663 and surmise that there must be some internal leakage around the first piston. This master cylinder is now obsolete but I have been able to source a seal kit (Part No. SP2486) but wonder how difficult it will be to successfully replace the seals. My car is low mileage so I am hoping there will not be too much internal wear.
Does any one have a diagram of the internals or advice on how to do this job? Alternatively recommend an aftermarket master cylinder.
Thanks in advance
