This! Just bleed that rear brake and it should be good to goIf you swapped in fresh pads in the rear AND topped off the brake fluid in the rear reservoir, there may not be enough room in the reservoir for the fluid to expand to account for the now much thicker pads.
Pull off the rear reservoir cap and follow proper bleeding procedure until the fluid level is no higher than the max line.
Yes, make sure you put that little guide clip in properly, or it could cause some issues.definately not the chain - it turns freely when the brake caliper is off also it was known okay as it was riding fine a day ago.
it has this small clip that looks like ]=[ that seems to fit between the caliper and the brake pad and seems to stop it from going all the way back - is this the correct place to put it?
I've pushed it til its quite far back and drained some of the liquid from the master cyclinder.
It only gets extremely tight when i fasten the 2 bolts that sticks the caliper onto the rotor
