I just bought an '87 190D and am trying to fix a problem with the brakes. The rear brakes (drivers side in particular) are staying engaged at all times. I thought that this was likely a problem with the emergency brake because of the fact that it was only the rear but after getting underneath and looking at it, I'm not so sure. The line for the emergency brake goes into the hub opposite the calipers and the hydraulic brake line which leads me to believe that it is not connected to the main brakes. Can somebody tell me if the emergency brakes operate through the same calipers as the hydraulic brakes? This is my first shot at working on them (obviously) so any insight would be greatly appreciated!
