Three problems related to brake sensor have been reported for the 1997 Chevrolet Tahoe. The most recently reported issues are listed below.
Abs activation during slow motion, under 10mph. This is the third time I've had this problem. Both times one of the hubs had to be replaced. This time I asked the mechanic to clean the sensors (as suggested by chevy service updates) to try and save money. It didn't work along with trying to replace the sensor. Now I have to have a hub replaced again. I've been luckily so far because I know of the problem, but I've had a few close calls with hitting cars in parking lots.
My 1997 chevy Tahoe had the same problem with anti-lock brakes as the batch of trucks in today's gm recall. The anti-lock brakes went on when the car was at very slow speed, like pulling up to a stop light or sign. I paid $300 to a mechanic to clean the same sensor in the recall. Why did the recall stop at the 1999 model year?.
Abs engages intermittently, dealer repaired vehicle at consumer's cost and also informed consumer that the vehicle was not covered under manufacturer's recall, front hubs and sensor were replaced.
