Having problems with my 1983 300sd brake system
I am having problems with the brake system on my 1983 300SD Turbo. I replaced the master cylinder, and the front left caliper. I bench bled the master cylinder and reconnected all 3 brake lines. Then, with the help of a friend, I bled the rear brakes and got fluid through the bleed valves and no air. I then tried to bleed the front brakes and got nothing. I didn't even get air after the brakes were pumped. I disconnected the brake line on the side that the caliper was replaced
and checked the output port with a vaccuum pump tool and I didn't get any fluid out of the port. Yet when I used the vaccuum pump during the bench test, I got fluid through the port.
