2015 SP rear brake pedal limp after siting for 4 months
I got my 2015 Hypermotard SP out of 4 months of winter storage and the rear brake pedal has gone flaccid and has excessive travel. Basically I have to push on it way down with my heel before any braking (weak) occurs. There is no sign of any fluid loss. No leaks and the reservoir is full of fluid. It does not build up pressure if the pedal is pumped repeatedly.
Any idea what could cause this and the fix? I was going to bleed it but is there a special procedure for bleeding the rear with ABS?
