Well, I'm finally tired of driving around with just my ebrake and decided to replace the master cylinder. After reading the rather vague Chilton manual, I have a few questions before proceeding. First off, the manual says that if the brake system is bled with the engine OFF then the vacuum booster can be damaged. Well, I am guilty as charged here. I replaced all the front brake components about a year ago, and bled the brakes without the engine running. So. . . Should I replaced the booster while I'm in there, or is the Chilton manual full of it? My original symptom is no pedal pressure. The loss of pedal pressure was gradual over about 5000 miles. The car does not lose fluid and the cylinder/booster area audibly sloshes and queeffs when the pedal is pushed. Second question: how do I properly bench bleed the master cylinder? Also, any other tips for working on the brake system of a 92 Loyale 5Spd 4wd would be appreciated. This site serves as a great reference tool. Thanks to those responsible.
