Three problems related to brake disc have been reported for the 1996 GMC Sonoma. The most recently reported issues are listed below.
We have had numerous problems with this vehicle sine one month after purchase including the idle sticking/interior moulding cracking/transmission rebuilt/computer replaced due to failure engine check light indicator light does not turn off, and right side brake does not seem to wear properly. . My husband is able to recall more.
Traveling 65mph on interstate pressed on brakes to slow down, brake pedal went to floor. Pulled to side of road & waited. Took vehicle to dealer. Mechanic said brakes & rotors were worn & needed to be replaced. Problem reappeared & a lot worse. Back to dealer & told pads needed replacing.
The brakes are warping every 6 months, causing a potential safety hazard.
