Default Give me a brake....

Last Saturday, being wet, Grant and I jacked up the C15a frame and did a brake adjustment on the beast.

Pedal had gone soft over the Winter. woerked according to the manual by raising all four wheels....... even ran the engine to see if they braked evenly.

Had a persisting problem with the front wheel cylinder not releasing properly...

Off came the wheel.... cylinder removed and checked for rust or dirt..... cleaned and re-installed....... voila.... except the brass junction block kept leaking ever so much..... tried various size and thickness of copper gaskets.... filed some burrs on the brass facings.... in all we assembled and reassembled about 5 times..... last one was lucky and it stopped leaking.....

I now have good brakes ....but.... still require one good pump to get a hard pedal........ I am asking too much of the old CMP......

We adjusted the lower cams and center snail cams on all four wheels and bleed each corner extensively....... why is it soft... I mean why is the brake pedal still soft to the first pump....... ???

We are talking SS sleeved master cyl. .... 4 new wheel cyl... new linings and arced drum to match lining profile....running synthetic brake fluid...

Do we need to bleed again.....?

Comments / suggestions welcomed......
