  1. Thanks for that ,I did not bleed the master cylinder , I did not know about that .I was thinking of bypass in the valve to take that out of the equation until I find the problem ,a few more possible leads , cheers
  2. Thanks ,yes rears bleed up well and loads of clean fluid has been pumped through ,not sure now what make the components are .Not two worried about the load sensing just need s decent reading on the rears
  3. Yes a bit strange ,do you Know if the two pipes from the abs unit are supplying fluid or is one a return , the possibility that they are crossed over is something I need to check . I have read that the abs unit has three pressure modes full braking half and none ,it would be fair to assume it is stuck on half power . With the engine running ,brake pedal pressed hard ,you can turn the back wheels by hand but it takes a lot of effort .The front brakes are perfect though .I think the dual circuit brake operates a front and rear brake per circuit which must mean something if it's both back brakes that are weak . Incidentally all the calipers ,pads and discs are new . An interesting puzzle ,any helpful ideas are greatly appreciated . Cheers
  4. Hi Simon ,thanks for that ,I will have a closer look for the markings ,it is motor factor replacement .I tried bleeding the brakes with the arm fully both ways and got plenty of fluid in both directions which I don't understand . I don't see the reason for it on a car with abs either but there must be a reason . Cheers Jonathan
  5. Hi Its my first post and already looking for help . I have a 1995 VR6 in the workshop that has been re-built with mostly new everything in the brakes and suspension department .We are getting low effort at the rear brakes and reckon it could be down to the proportioning valve. which is new . I have tried it in with the lever both ways and it makes no difference and I am wondering if it has been plumbed incorrectly . Does anyone have a diagram or a good picture showing the pipe layout . We have a good solid pedal and have bled at the abs unit as well .The front brakes are excellent . The car was completely stripped for over a year so we could easily have our pipes crossed . Any help would be greatly appreciated . Thanks Jon
