I’ve read all the threads on bleeding and adjusting brakes, but I still got a problem. Replaced the master cylinder and two rear cylinders. Bleed the master before putting into place. Then replaced the two cylinders at rear as one was leaking. Bled the brakes as instructed in posts I.e. farthest first working to nearest. Have drum brakes on front which have two cylinders each and they pretty new. Problem I have is it pulls to the right and can feel the rear right lock, but left side while it brakes is not as efficient. Starting to think that the new cylinder on rear left is faulty or seized? Any help and advice would be greatly appreciated
