Rear brakes sticking SIII
the rear brakes on my 1973 SIII SWB are not releasing fully,
at first pump on the brakes, the rear brakes respond, nothing from the front, then a second pump and all brakes working together as they should.
I'm pretty sure the master needs replaced or needs a kit, i've been loosing fluid slowly, and there appears to be fluid running down on the servo unit.
I have not touched the shoes so am assuming they are fine. Does this problem sound like the master playing up, or the brake failure valve or a combination of the two. Can anyone help me out??
