My drivers side disc and pads are binding so much that even the wheel gets hot.... They are new discs and pads etc..... I took the wheel off today to see if i could see much and to see if it was just a build up of dust but it appears the caliper pot is holding the brake on... I took the resoviur cap off and tried to push the pot back..but it woudln`t budge... i then thought that it would be an idea to undo thebleed nipple... but its broken off in the caliper... Now what...bigger hammer on the pot...?
