extreme90:
check wheel bearings
this is the tell tail sign  :wink:
i had a broken up inner bearing ont front axle of my 90, and it took me ages to figure out what it was

pump the breaks up, 100 yards down the road in stright line its fine

go 500 yards or turn, had to pump the breaks again

davidlandy:
I would second the wheel bearings as TBD has said- the disc moves side to side on the bearing and forces the pistons back a tad - the result is that you have to pump the brakes to get the pedal back.

Its happened to me a few times!

:idea:  :!:  ok cheers had not thought of that,  I will check because I repacked grease on the front bearings about a week ago and maybe they are not adjusted correctly or have slacked off.

Cheers guys your diagnostic was spot on! Front nearside bearing had loosened right off with a lot play :shock:  Now adjusted with brand new lock washer fitted. Brakes back to normal.
