Re: Rear Brake Drag 3/16/2016
I also agree on the master cylinder being the problem. There was no drag before changing the master cylinder and no ABS faults are present.
I think that you can check if the problem is with the master cylinder doing the following: apply the brakes and release them. Now loosen the hydraulic line from the rear brakes on the master cylinder a bit and catch the fluid. A little bit of fluid can come out, but there should be no pressure on it. If it holds pressure there, then only the master cylinder can keep it there.
