Shackleton Posted March 4, 2008 Share Posted March 4, 2008 Stab in the dark is a loss of vacuum to the servo? What truck? Quote Link to comment Share on other sites More sharing options...
steve_d Posted March 4, 2008 Share Posted March 4, 2008 Have you had the brake pedal assembly apart? This problem (not unique to LR) is normally when the rod and master cylinder piston do not return full travel at which point a port in the cylinder is opened allowing the fluid you sent to the brakes to return. Things to look for are: Failed pedal return spring or pedal itself sticking. If the mechanism has been dismantled and not refitted correctly. Servo sticking or leaking diaphragm. Early sign of the master cylinder seals failing where they become soft and expand. On that note have you used DOT5 fluid which can do this to some seal types.

Pete Attryde Posted March 5, 2008 Share Posted March 5, 2008 I would agree with Broonie. New Flexi's should sort it. Pete. Quote Link to comment Share on other sites More sharing options...

steve_d Posted March 5, 2008 Share Posted March 5, 2008 A collapsed flexi would only lock one brake on or perhaps the back ones but not all of them. Steve Quote Link to comment Share on other sites More sharing options...
alfredenewman Posted March 5, 2008 Share Posted March 5, 2008 A collapsed flexi would only lock one brake on or perhaps the back ones but not all of them.Steve try when its been used and the brakes are locking releasing a bleed valve on both front calipers if there is presure there and it frees the brakes of it almost certainly the servo good luck Quote Link to comment Share on other sites More sharing options...
