If I take the cap off the master cylinder and put it back on, I have a rock hard pedal that instantly locks the rear wheels up when pushed. All original parts. No leaks that I have found. Any help would be great. I would like to fix it myself but not sure what the problem is. Booster? Master cylinder? | | | | | Joined: Oct 2007 Posts: 725 Shop Shark | | Shop Shark Joined: Oct 2007 Posts: 725 | The vent in the cap is stopped up. Look for a vent and make sure it's clear. It is usually just a small hole with an off set hole in the gasket on either side.
good luck,
Les | | |
