Eight problems related to brake master cylinder have been reported for the 1999 GMC Suburban. The most recently reported issues are listed below.
For a brand new Suburban I don't feel it should be having major part problems. No safety defect listed.
Repeated excessive wear on front brake pads and now on rear brake drums. We are very conservative drivers and typically get 80-100,000 miles on a set of brakes. This is our second set of front pads. We do tow heavy loads. The Suburban is equipped with a heavy duty towing package . It has already had the steering gear box replaced by the dealer. The front pads have been replaced once and the rear brakes have been adjusted, also the master cylinder has been replaced by the dealer. The brakes just do not seem of sufficient capacity to stop a vehicle of this mass towing load. We've owned Suburban's since 1973 so we do feel we have a degree of experience in this area. Finally when the vehicle is driven at highway speeds and a bump is hit, the entire electrical system shorts out for approximately 1/6-1/5 of a second causing everything to go dark. I suspect an exposure in a wiring harness. *****dimsii ivoq entry posted after 12/12/02 cut over to artemis****763731.
Have had ongoing problems with the braking system of this vehicle, can provide copies of all failures.
I've had this vehicle in for brake repairs at least 6 times since I bought it. It now has 26,500 miles. The brakes have been replaced 4 times, master cylinder replaced, proportioning valve replaced, and right side caliper replaced. I have also had the following replaced: motor pulley, a/c compressor, tie rod, idler arm, pitman arm, coil in steering column, main belt, front differential gasket. Every time I take it in to the dealer, it seems that I am a pest. . . . . . . . I will never own another GMC product, and I am seeking legal advice for a possible manufacturer buyback.
While driving experienced problems with abs brakes and master cylinder .
No summary.
The a/c stunk; I felt insecure with the brakes soft most times. Twice we drove 45 mi. To midway and they did not take the vehicle in, GMC said to go to nearest dealer.
1, seal on master cylinder is leaking brake fluid . Master cynlinder has been replaced twice. 2, side mirrors vibrate excessively, resulting in poor visibility. Please provide further information.
