Hi,i have a 78 with disc front, 10 bolt rear, my drivers side rear drum brake keeps locking up, ive renewed the shoes drums springs etc, ive tryed bleeding front to rear / rear to front, furtherest to nearest, near to far, adjusted in & out, swaped drums over, im 99% sure i havent mixed up trailing & leading shoes as they seemed to only go on 1 way, i did 1 at a time when swaping everything over, & copyed another car i had at the time, i put new park brake cables in which is how it all started, i dont remember it locking up b4 i did the new parts, ive googled & u-tubed as much as i can but am at a loss to sort it. if any1 has sum tricks to try PLEASE let me know. Thanx in advance! its my last hurdle to get her road legal!
