Just changed the rear pads on my SE2 1.8 Coupe, after driving a bit the slower i go there is a loud humming noise from the back that goes away when touching the brake slightly, the slower i am moving he louder it is, its a constant drive under 30mph, when crawling its deafening loud. Cant see why they might be binding if this is the cause took caliper off again the removed 2 piston rods and greased ect cleaned again still same. Noticed aswell after driving 11 miles or so from the pads to getting done and stopping at petrol station my driver side rear brake was smoking and VERY hot! So dont want to drive very far! any help would be good!
