I put up a post a while back about my difficulties with rear brake calipers - eventually decided to get a refurbished pair as the handbrake levers weren't working correctly on the ones on the car.
Anyway - having fitted the new rear calipers, rear discs and new pads all round I'm really struggling to get the brakes to work effectively.
I believe I've got the rear adjusters sorted OK, with 0.25mm of pad to disc clearance as in the factory manual.
Despite bleeding 1.5 litres of fluid through the system (and hours and hours doing so), I've still got weak pedal feel, it is soft and has what I think is too long a travel.
Generally I'm bleeding with an Eeezibleed kit set to ~15psi, and have also bled using the pump and hold method with a helper. The rears I've been bleeding one side of the car at a time with two bleed tubes.
Is there likely to still be air in the system somewhere?
The proportioning valve seems to be working, and although the rubber cover is missing the piston pin moves out when the brake pedal is pushed down.
Interestingly when the engine is started (so there's vacuum assist from the servo) the pedal seems to get softer....
Looking through some posts on here tonight I've picked up some info on some checked to do on the servo and the one-way vacuum valve from the intake manifold, and I will report back on these once I know what's going on with them.
Now we're losing the light in the evenings I've got little time to spend getting this sorted so would appreciate any and all assistance to get my 75 through its MoT and keep it on the road. It's been off the road for 8 weeks now trying to get these brakes sorted and I'm close to giving up as I can't make any progress
