I replaced all the brakes including the MC. After the brakes were bled I have a vacuum hiss down by the pedal. Is The boot around the rod causing this??? It stops fine but the leak is really annoying. This is a Power Brake '79 Volare. |

Failed power brake booster. Don't buy a Cardone unit. Send your original to get rebuilt at http://boosterdeweyexchange.com |

Before condeming the booster, make sure the bushrod between the booster and the mc has free play. Also make sure the pedal pushrod is not keeping pressure on the booster, when released. Both need a small amount of free play. |
