Byron, As the booster gets older the seal begin to fail. We rebuild the with new seals and warranty them for 5 years.$125.00. Normally if the brakes are hard to push down it's the booster. But if the brakes are soft and they take a pump or to, to pump up then it's the master cylinder. Real easy to change. I sell new ones with a 5 year warranty for $79.00. John Hervey http://www.specialtauto.com/delorean-parts/brakes-rotors.html But, Before I would replace it, I would replace the master cylinder which is real easy to replace and it can be done -----Original Message----- From: dmcnews@xxxxxxxxxxxxxxx [mailto:dmcnews@xxxxxxxxxxxxxxx]On Behalf Of byrondelorean Sent: Tuesday, July 26, 2005 8:38 PM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] Brake question Dear forum members, when I step on the brake pedal, it feels as thou the pedal has too much play before making contact with the brakes. Maybe 4"-5". The brakes do not feel different when I pump them. I brought it to a nearby brake shop; but am leary to have them touch the car. I get the confused look; and my feeling is to just drive away. Dave Bauerle recently worked on the car and suggested it may be the master cylinder. I would like to get this fixed in a suburb Detroit area. Is there a formal way of explaining whats going on with my brakes with a local brake shop? The last shop said " I don't know what the pedal is supposed to feel like". Could it be more than just the master cylinder, maybe the brake power booster? If both items need to be replaced, should I order every gasket and connection piece associated for the removal & installation? Thanks for the help.
