My right rear wheel is making an obnoxioux "burning rubber" smell, but under specific conditions.
After I've been travelling usually in excess of 60mph for a while (eg on a motorway) and come off on the slip road... there's a nice smell eminating from right rear. This is usually followed by brake fade too.
Braking on the slip road, gives a sort of slight bunny hop sensation...
I can trundle round all day at 40 mph and brake all over the shop with no problems.
I recently had my left rear caliper changed, but afterwards, noticed that the right hand side also had copper grease on the brake shims - presumed the garage had a fiddle with that caliper, which would make things really coincidental if it were the caliper at fault.
But Im inclined to think (given the speed issue), that maybe the bearing is getting superheated at high speed causing the discs et al to overheat or something?
