Title: 77 c20 brake problem
Post by: 1979C20 on October 12, 2011, 02:45:51 am

On my brothers 77 c20, the brake pedal goes almost to the floor with no resistance, then gets hard. I tried to bleed the brakes just now and there was only a dribble at both sides on the rear, and the fronts had decent pressure. Any ideas why? And, the brake fluid in the rear reservoir on the master keeps draining

If the master drains it's got a leak that you have to find.
