*xj-man* Posted October 3, 2013 Share Posted October 3, 2013 I just swapped in a new WJ booster with a used MC. Everything is hooked up and I made my own brakes lines with the correct flare for the MC and prop valve. When I go to step on the pedal or pump the brakes I don't get any pressure in the pedal. Am I missing something? Link to comment Share on other sites More sharing options...
zackcj7 Posted October 3, 2013 Share Posted October 3, 2013 Did you bleed the system correctly? Including bench bleeding the master cylinder. Link to comment Share on other sites More sharing options...
Akula69 Posted October 3, 2013 Share Posted October 3, 2013 We had fun the last time we did the brakes on one of the systems. Bled everything, and went back through it about 5 times (going through three quarts of fluid!). Turned out I had to crack the lines free from the distribution block while someone pressed the pedal to remove the last stubborn air bubbles. Had brakes after that.

*xj-man* Posted October 3, 2013 Author Share Posted October 3, 2013 I'll try to rebleed the system. Link to comment Share on other sites More sharing options...
carnuck Posted October 10, 2013 Share Posted October 10, 2013 The return line from the rear gets air in it and has to be loosened to get it out or swap to a 2 line valve from an XJ Link to comment Share on other sites More sharing options...
