Servo in at last and just trying the master cylinder in place to check the pipe runs. BUT I seem to have discovered an alarming latent error from build. My understanding of the Sierra dual braking circuit is that the single output pipe from the rear (primary) piston goes to the rear brakes where it divides at the axle. The two output pipes from the front (secondary) piston each go to one front brake. That way if the rear fails you still have the front brakes and vice versa. Does everyone agree? With my system the rear brake pipe goes to one of the front cylinder outlets! Pipes were identified to M/C before disassembly and lengths are different so not an eror by me. Would appreciate any confirmation / comments before I do some major re-routing of the m/c connections to correct this. Peter.
