Rear brake not working

husqvarnapete · May 25, 2017

Rear brake peddle not working, when pressed,
Rear brake works when front lever is pulled, but not from the foot brake,
I can hear the servo working when the peddle is pressed though!
Any advice ??

I think that only one piston is operated by rear pedal and one by front lever, not sure though. Try taking caliper off and make sure it is free on the sliders, very common to seize. Once off try pressing rear brake"gently" see what's happening.

Ok so I've tried to bleed the rear brake bit nothing is happening when pushing down on the foot brake pistons both work when the front lever is pressed though I'm thinking it could either be the rear master cylinder or the servo, how big of a job is it to get at the servo? Before I start taking parts off?

Servo accessed by removing fuel tank.

Good brake bleeding procedure for the servo brakes here: http://www.ukgser.com/technical/nick/Brake bleeding (All BMW EVO systems, '04-'07).pdf
