Brakes-when coming to stop pedal is hard then drops about an inch more before vehicle stops.anti lock will sometimes engage and stop vehicle. After vehicle stops I can continue to push pedal all the way to floor. Dealer replaced rear dump valve but problem still there. Master cylinder has been replaced, new rotors, new back brake shoes(3rd set). Brake problem started in Jan 2001. Intake gasket is leaking. Fuel pump is running very noisy, nosier than when new. I know that this means it is going to go.so I will have to replace it.

My vehicle ran head-on into the side of a car that ran a stop sign. My car was so damaged that the insurance adjustor "totaled" it. The impact was so severe that I, the driver, sustained a fracture of the sternum (I was wearing a seat belt with shoulder harness). The air bags of my car did not go off, but the air bags of the car I hit did go off. On impact the brake mastercylinder with the power assist unit was broken off the fire wall by the ABS module. Therefore I did not have any brakes and rolled for another 300 feet before coming to rest against a tree in the lower shoulder of the road.

I had problems with the brakes once. They just filled up the brake fluid. 2nd time they replaced the master cylinder. I had problems with the electrical. They said it was the wiring harness at the engine.I had problems with the air conditioning. Took it in two or three times for that. They replaced some switches. Then had to take it in again and they replaced the rear airconditioner. We purchased this truck to pull a 20 ft trailer the trailer weighs 4200 lb. The Suburban has a 3.73 differential and the trailering pkg. Plus post traction or whatever thety call it now! we went on a vacation in Nov. Planning on being home the 1st of the year. Our !St differential broke outside of frederick md. It was replaced. Upon trying to return home the 2nd differential broke! it was replaced in louisville ky. Continuning our Venture home. The 3rd differential went out in mobile ala. They gave me a very difficult time. Told me it was my fault. I was either going too fast of the trailer was too heavy. Neither acusations were true! upon finally arriving home (almost) the 4th differential went out and replaced. I have lost all faith & trust in this vechicle. Am scared to death to take it on the road. My husband is 67 years old and has dreamed of his retirement all his life. Now we are stuck with a Suburban we don't dare take on the road for fear of it breaking down again. Chevrolet refused to do anything about it. The garage we purchased it from has been very nice. However, they also have been no help in this issue! any help you can give pertaining to Chevrolet replacing my Suburban wouyld be greatly appreciated.
