| I have two problems with the abs and brake pedal surge on my 1997 silverado ext-cab k-1500 z71. under light braking conditions the brakes momentarily engage followed by short intervals of pressure/loss of pressure until the vehicle stops. i have never lost (at least until this point in time) complete brake pressure. the second problem occurs when the brake surge is not present. in this case, the abs system activates. the brake problems occur everytime the vehicle is driven (dry and wet conditions). i have had the truck serviced twice in the past month, and my dealer cannot locate the problem. their recommendation is to start replacing brake component by component until it is solved ($$$). their comment to me is that the rear brake system (that's the area that my dealer is focusing on) is a poor design by gm. | |||

| I currently own a 1997 silverado ext cab fleet side. i've had my brakes serviced numerous times and it continues to pull to the left when i'm braking. also it's very hesitant in picking up speed when passing even with major tune-ups at chevy dealerships only to be serviced. i'm constantly purchasing front tires for my truck, with front end alignments being done often with the purchase of these tires. *jb | |||

| The issue that has just caused the 800,000 vehicle recall for gm, the issue with the anti-lock brakes, is on vehicles older than the 1999. i have a 1997 silverado and was having the problem of the anti-lock brakes engaging at low speeds, it started happening in 1999 and got worse over time. we took the vehicle in for repairs and they replaced the sensor that triggers the anti- lock brakes, at a cost of several hundred dollars. they said this sensor gets dirty and then fails. i am concerned as to why the recall is only going back to the 1999 models when in fact the problem is occurring in older models as well, as i said mine is a 1997 silverado.*jb | |||

| The a/t hesitates coming out of a turn at 15 mph when accelerating and is slow to shift up in gears. on wet pavement the transmission catches and spins the rear wheeels causing the vehicle to go side ways. this has been annon going problem. the dealer put in a new transmission when it was only going to be serviced. i was charged $2,600.00 for the transmission. the only problem is it does the same thing and now leaks fluid. the hotter the transmission gets, the worse it performs. the anti lock brake system does not operate evenly on the brakes. this is evident on the unusual wear to the rear brakes. on an emergency stop the rear brakes lock up. in the past the dealer said it was because there is no weight in the bed of the truck. i have battled and repaired the brake system since purchasing the truck. finally everthing mentioned gave out, the only response from the dealer was that the truck has to many miles. additionally i have filed a complaint with the state of california automotive consumer affairs for the concerns, false and misleading statements, writings by the dealer. the vehicle is somewhat ok on dry pavement, but loss of control on wet pavement. i did contact chevrolet assistance in writing. they acknowledged my response, but declined to discuss the defects with the transmission and brake system.*ak | |||
