Hi all, giving my k11 bit of a service and check at the moment and have taken the rear wheels off to respray. Having removed the wheel and released the handbrake have noticed a tight spot when spinning the drum. Does anybody have any idea what is causing this? It is on the rear passenger side only (other drum is fine). Also where is the best place to buy a new drum if neccessary? Ebay varies but a place i found online (buycarparts uk) are charging 16 Squid a side? Seems very cheap? Your thoughts are always greatly appreciated!
