OK, the time had come to replace the fluid in the Project car since it's been sitting for so long.
Sucked out the reservoir(s) and refilled with new fluid.
Pressed Mrs P into service as a pedal presser and bled both front calipers until bubble free and clean fluid emerging.
Topped up MC reservoir.
Went to left rear and achieved some throughput, not convincingly good but enough to move new fluid in I reckon.
Right hand assembly. Nothing comes out! Bugger.
Mrs P went back to her daily doing while I thought about it and decided to have a short drive up and down the street anyway.
Brakes: good pedal feel, just not really good retardation. OK, may be the pads, I'll fit new ones any way but let's chase this further.
Up on the hoist again and back wheels off. Strip the rear brakes. Dismantle wheel cylinders and they're really dirty inside, but only stiff, not seized. Clean, hone and reassemble, all good so far.
Created a home brew pressure bleeder connected to a 5psi source. Fronts. bleed lovely. Left rear bleeds lovely. Right rear still being a mongrel.
I think I've narrowed it down to the right rear flexible hose. Nothing coming out of it. I'm discounting the pressure limiter (Found it under the bonnet), the longitudinal pipe and the tee piece above the beam.
When I get enthused enough to squeeze hands and fingers in there I'll (try to) disconnect the pressure end of the flex hose and confirm the above. In the meantime I'm thinking new flex pipes all around might be prudent.
The brake pedal feels good, however, but obviously without any pressure getting to the right rear the self adjusting can't operate. That's a secondary consideration once I get fluid coming through.
Can't believe a simple split system brake setup is fighting me back so much.
Oh, and it's not diagonally split as far as I can tell (Haynes thinks it is!) and realistically I can't see any reason why it would need to be.
Ah well, learning curves are never flat!
Oh and for reference, three port master cylinder, discs front drums rear. Rear slaves Girling pattern, but Lockheed embossed on them!
Cheers, Pottsy
