Long story short, i put on a new refurbished axle, new flexis and all new copper brake lines. Only thing not changed was the brake compensator valve. I did put on a new spring (ebay) and set that just touching the lever. Bled, away for mot.
It failed on rear brakes imbalance and I overheard the tester complaining about not being able to lock up back brakes and that the arm was just "flapping about"
Took it back, bought a brake pressure test kit.
I have rigged the kit up last week and read the citroen docbox i have on my computer (ahem)
It says to set the front to 1450psi and read the rear pressure. As far as i understand, lever right out should only just be over 20bar. It wasnt, and i have a left/right imbalance, so i have changed the valve.
Now this is where the fun begins..
Setting the front to 1500 the back is only reading just over 100psi. Moving the lever has no effect, and front @ 3000psi has no effect.
Have i knackerd the master cylinder? I took the back gauge off, set front to 3000psi and i can still grab my rear drums and turn them if i put some effort in.
I am still to swap gauges and check for reading issues. I cant understand why i was getting too much pressure on old valve and now new valve is giving very little.
Thanks
