| 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. | ||||||

| In a letter dated april 20, 2005, gm notified nhtsa that it had decided that defects that relate to motor vehicle safety exist in certain model year (my) 1999-2002 c/k 1500 series (pbr parking brake system) and my 2001-2005 c/k 2500 and 3500 series (trw parking brake system) pickups with manual transmissions.according to gm, some of these vehicles may have conditions that cause the friction linings to wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.gm's action covers an estimated total of 142,585 vehicles.dealers will install a low-force spring clip retainer for vehicles equipped with the pbr parking brake system and install a redesigned parking brake cable assembly on vehicles equipped with the trw parking brake system. a total of 58 non-duplicative complaints were received by odi and gm concerning the approximately 59,000 my 1999-2002 c/k 1500 series pickup trucks with the pbr parking brake system.these included 22 alleged rollaway incidents, resulting in a rate of 38.5 rollaway incidents per 100,000 vehicles.odi is aware of 24 complaints regarding the my 2001-2005 c/k 2500 and 3500 series manual transmission trucks recalled by gm, including 5 alleging rollaway incidents.though the conditions described in gm's letter are also present in the c/k trucks with automatic transmissions, the rollaway rate in those vehicles was similar to those observed in peer vehicles studied by odi in this investigation.this engineering analysis is closed. for additional information, see the attached closing report. | ||||||

| Parking brake and fuel gage. i recently moved overseas with af and had to have my vehicle inspected for european standards. my parking break did not work at all. i found this hard to believe since i have never used it. i was mandated by european law to get fixed in order to drive it and pay a $30 for each month until i got it fixed. my fuel gage doesn't maintain how much fuel i have in my gas tank. when i have a full or empty tank the gauge just randomly boucess around with the unknown correct amount. i am currently setting the mileage until i can find someone to fix it and the parts i need. *tr | |||

| We purchased a 2001 silverado ext in 7-01. truck had about 16,000 miles on it, when we bought it new/used. parking brake seemed to be really soft, but lot assured us, nothing was wrong with it and that the new technology we had with vehicle's, made it easier for elderly people and such. yes the brake works great on level ground, but wait until you really need it like on a sloped driveway............. or getting the vehicle inspected! this is when they really give you the works!!dealership wanted to charge us almost $200 to fix a 15 minute job, which should have been fixed while it was under warranty. we had an unfortunate incident, which resulted in the death of another person. to make a long story short, i feel it may have been prevented, if these(so called) great anti-lock brakes on gm vehicles did what they are supposed to do. we have encountered several occasions where the brakes go to the floor, get really spongy, even when constant pressure on pedal is maintained, and the result is erratic! what happened to the gmc/chevrolet brand?! ----p.s.- we were told this is a common complaint on the parking brake, but yet there is no recall on a safety defect?! by the way, gm this is the last vehicle purchase we will make from you. it seems the quality and safety factor mean nothing to your company anymore, without trying to make more money from the consumer...oh well, just one less customer!! *cb | |||

| Vehicle was parked, pressed parking brake and brakes went all the way to the floor. consumer contacted dealer, and they stated that it was normal. *akthe consumer checked several other gm trucks and found that some of their parking brakes also go to the floor, the consumer is concerned that when adjustment is needed the adjustment rods will have no adjustment left, the consumer believes that the wrong cable length was used either front or rear. *nlm | |||
