Under certain driving conditions the switch which signals the ABS system whether the vehicle is in 2-wheel or 4-wheel drive can malfunction causing increased stopping distances during ABS stops while in the two-wheel drive mode.

What 1993 GMC Sonoma owners say
Most recent owner complaints, unedited.
The main computer failed.
When applying brakes the pedal went to the floor, and the vehicle did not stop. Dealer could not duplicate problem.
I have tried calling a dealer - they know no more than I do. Help!!
When driving vehicle at various speeds, ABS brakes would fail to stop vehicle. Would fade out, and stopping distance has been increased. Vehicle also hesitated in reverse. When in drive position would ramble & lose power. Also, there are defective valves in engine. Also defective driveshaft rubber bearings cause vehicle to vibrate. Have taken vehicle to midas & not dealership. The problem could not be solved.
When braking on wet pavement, brake pedal goes to pedal stop and vehicle is not stopping. The dealer has put on brake booster, ABS dump valve master cylinder bled and adjusted brakes. Gmc was involved with diagnosis. This was done one year ago truck still does this. I realize recall under way involving 4wd vehicles but not two wheel drive. From what I have read sounds like the same problem. How should I go about getting this resolved? So far about $1800.00 has been put into this problem. I do not know where to go get a resolution to this.
While driving at 55 MPH and applying the brakes, the brakes went straight to floorboard, and the ABS didn't work . Also, engine check light kept coming on.
Brake fluid is running out of vehicle while driving or parked. Dealer notified, and will not repair unless cost is paid by the consumer.
When applying the brakes the pedal went to the floor and the vehicle didn't stop. The fluid was gone, but no brake fluid light came on, fluid was leaking. Dealer has not seen.
Anti lock brakes lock up in wet weather.
