My rear brake is about 5% effective - actually, more like 0%, as I cannot stop the bike, even under 10mph.
A little history:
2006 950 Adventure
OEM pads/rotor, 24k miles (all road).
Pads 6mm thick.
Had a light oil contamination on pads/rotor last week (don't ask. . . ).
Pulled, cleaned and sanded pads and sanded rotor today. Nada.
Fluid changed summer 2010. Free play is good.
There is some pressure at pedal, no pressure being applied to the rotor.
Can the wheel cylinder 'blow by' the seals when the brake is applied?
Any help would be appreciated. Thx -
