Hi guys, Ok, been suffering with a bit of a problem with my back brake on my twin cam GSA. Everything was hunky dorry and working as it should up until a few months ago when i took the bike for an mot and the guy advised that the rear pads were getting a bit low so ok not a problem so I ordered a set and fitted them and right from the get-go I noticed the brake didn’t seem as powerful as it was before, quite a lot less powerfull in fact!
So anyway I carried on riding it and soon got used to the less than powerful back brake then went abroad and started experiencing a lot of screeching from it when braking, when I got home i took the pads out and they were cracked and looked like they had overheated so I checked that the sliding pins were sliding freely, which they were and I fitted another set of pads (different brand this time) re-bled the brake just to be sure and again it seemed very low on braking power, this time however it occurred to me that the brake may be binding slightly so went for a ride and trying not to use the back brake, stopped and put my hand on the calliper and sure enough it was quite hot but on spinning the wheel by hand I couldn’t detect any binding at all.
Stripped the whole calliper down this time, pins running freely, seals not leaking and no crap in the caliper preventing the pistons going back although the pistons did seem quite stiff to push back in once i put it all back together? Put it all back together bled it again and went for a ride today and the brake barely works at all now, checked the calliper for heat and yes yet again it’s running quite hot so must be binding I guess?
Anyone seen anything like this before?
Thanks and sorry for the long post!
