supersub14 1 Posted July 2, 2008 Hey all, my '92 205 1.9 GTI failed mot tonight there. The rear brakes were showing a difference of 47% and the tester said that the most your allowed is 30%. How do i fix this? Im not an expert mechanic but i know my way round the haynes manual lol He said the handbrake was fine and it only happened with the foot brake. He mentioned something about a adjusting a regulator?? If i bled the brakes would it make a difference? Thanks in advance for any advice Share this post Link to post Share on other sites
welshpug 1,657 Posted July 2, 2008 what actual figures did you get? most common problem is that the compensator on the strongest side has gone open circuit and is not restricting the flow of fluid. Share this post Link to post Share on other sites
Baz 421 Posted July 3, 2008 Compensator would be my guess too! Share this post Link to post Share on other sites

RonnieG 0 Posted July 3, 2008 Thats not a mile away and rear brake im-balance can be a nightmare to trace/resolve ! I'd be tempted to bleed the rear brakes & swap the passenger & driver rear wheels round then try and just ask the MOT tester if he could just test them for you to see if you've done enough for them to pass before delving any deeper......

supersub14 1 Posted July 5, 2008 what actual figures did you get? In the brake Test section: does this mean anything to anyone?? Share this post Link to post Share on other sites
supersub14 1 Posted July 29, 2008 UPDATE...... Bled the brakes and took it for retest. Didnt make the slightest bit of difference when the guy tested them. Still produced a reading of 47% Luckily enough the guy liked the car and gave the hand brake a wee touch when he was testing them lol Passed with flying colours Jammy bas....

DamirGTI 342 Posted July 29, 2008 (edited) Duff compensator (theres two of them on 1.9 system ..) , partially clogged rubber flexi pipe , or sticky hand brake mechanism (a bit unusual for cars with rear disc brakes , but i've had brake imbalance because sticky handbrake mechanism on a 1.6 car , with drum brakes ..)
