Title: rear abs brake bleed problem K75
Post by: bernoulli on May 25, 2014, 10:40:57 PM

1994 K75RT with ABS.

. There is not enough pedal to activate the ABS even on loose gravel. 
I'm guessing there must be a air leak somewhere? Thoughts and comments appreciated.

are you bleeding slow... unlike a mash mash mash hold and open like a car... its open + slowly push... close + let up... repeat... also gotts to bleed abs modulator 1st... caliper 2nd...

do you still have the rubber brake line... if so... could be its just containing the pressure like it used to...
