I've now split the brake pipe to the front of the rear compensating valve to see if I'm getting fluid to the rear of the car and only a dribble of fluid coming through , ignition on position 2 and foot on brake. The pump is priming as it should.
Im thinking maybe the distribution block at the front of car is at fault.
am I right in thinking I should be getting high pressure to the rear of the car?
Also is the later 4x4 distribution blocks be used on a 3dr as these are all that's available on eBay at the moment.
thanks for any help info on this would be much appreciated.
