Brakes

[daveb11]

Have just had my 172 cup in for its (first) MOT. It passed, but only just. Problem was the rear brakes. Seemingly they were only 20 odd percent efficient, and if it hadn't been for the fronts being so good and bumping up the overall efficiency then it would have failed. Has anyone else come across this problem? Dont believe it is the discs or pads - they seem to be ok and braking feels ok (no spongy pedal). Realise that the back brakes don't do a great deal anyway but surely this cannot be normal. Any ideas???

Rear brakes are usless on the cup you need to brake hard a few time to get the rust of them sometimes.

if the discs and pads are fine... it could be fluid related.

try bleeding/changing the fluid
