| PE03057 | GENERAL MOTORS CORP. | 12/08/2003 | 04/09/2004 | PARKING BRAKE FAILURE | ||
| Odi opened pe03-057 to assess parking brake ineffectiveness in the subject vehicles.these vehicles are equipped with four wheel disc brakes that incorporate a single-shoe drum-in-hat parking brake independent of the service brakes.complaint and warranty data indicate that the parking brake linings tend to wear out early in the life of the vehicle (at an average of 24 months in service), reducing the parking brake system's torque below that needed to immobilize the vehicle.gm has attributed this accelerated wear to foreign material intrusion and a failure of the brake shoe to properly self-center within its brake drum.effective with the start of my 2003 production, a newer reduced force hold-down clip was introduced to facilitate brake shoe disengagement from the drum surface.this part is also available at the service level for the my 1999-2002 vehicles.gm has indicated that the paking brake is intended to operate in conjunction with the transmission to immobilze parked vehicles, and that in many cases, accelerated parking brake lining wear is caused by rough use, vehicle modifications, and driving with the parking engaged. odi has upgraded the preliminary evaluation to an engineering analysis to gather further information concerning parking brake usage factors and the circumstances surrounding the seventeen reported vehicle crashes. | ||||||

| Parking brake (e-brakes) failure of chevy silverado 1500 z71 with 4-wheel disc abs brakes. truck purchased new from family chevrolet in shingle springs ca. e-brakes never worked from day one, however, i was told this was how they functioned due to 4-wheel disc system (from dealership)-wrong. after asking other chevy truck owners with the same e-brake system, they too experience the same problems. i am very surprised that gm did not send a recall notice out for this problem. though gm did send out a recall on the tail gate support cables, i find this problem much more of a safety problem since the e-brakes are suppose to hold back a 2 ton vehicle of which it does not. a mechanic from les schwab tires (and brakes) told me after he inspected my e-brake system that he has seen this problem continuously occurs with this type of e-brake system with gm trucks. *nm | |||

| Premature total parking/emergency brake failure. failed texas vehicle safety inspection. vehicle inspector informed me the same failure was common among 2002 trucks like mine and warned of a costly repair. parking brake was very seldom engaged yet became totally worn out at some point prior to vehicle reaching 50,000 miles. dealer admitted to a poor design but said there was no recall. he said a bulletin was issued to replace the junk part with a beefed up version. my repair cost exceeded $400.*jb | |||

| 2002 z71 silverado chevrolet truck pertaining to anti-lock brake failure: one month after warranty expired the failure occurred. the problem resulted in unwanted abs activation and increased stopping distance during low-speed brake application. gm indicated that the condition can occur if corrision forms under the wheel speed sensor and moves the sensor away from the intergral speed sensor toothed ring. the condition does not set any abs codes nor does it illuminate the abs warning lamp. it is obviously a manufacturer's malfunction making it very dangerous to drive. i personally know of several people who have had the same problem. | |||
