I found some information on an emergency brake recall at http://gm-trucks.com/home/content/view/179/49/. Does anyone know more details such as procedure and part numbers. I'll eat the cost now, as my emergency brake is completely useless. I've cleaned and adjusted, and it will roll on the slightest incline.

A safety recall for 142,585 (1500 Series) 1999-2002 Chevrolet Silverado and GMC Sierra pickups and (2500/3500 Series) 2001-2005 pickups with manual transmissions for parking brake friction than can lead to parking brake ineffectiveness and possible movement of unattended vehicles. GM is aware of 26 crashes and one minor injury that may be related to this condition.
Well, mine is an automatic so I guess I am left out in the cold. :cool:

Not much movement with unattended "Automatic's" in Park. :D

Yeah but I don't like letting the tranny hold the weight of my truck back. I NEVER parked my 99 OBS Z-71 without setting parking brake first - then put truck into Park. I find that if I park the HD facing down grade it will roll against tranny no matter how far I push the parking brake. It does okay if level or facing up grade.

i never let it rest on the parking pawl either. always foot on brake, shift into park, apply parking brake, let off brake. even though i hear they can hold around 20,000lbs or something? just a good habit to keep.

and why would you handshakers need a parking brake? put the thing in gear when parked, and you surely dont need to use the parking brake if your trying to get moving from a stop on a steep hill.... i mean 1st gear is low enough right just let up off the 3rd pedal. doesnt mean you shouldnt have it checked out, i mean it is a $40,000 truck ;)

nosliw, whenever you need to stop and leave the engine running(to get out and open a gate for example), you need a parking brake. Just try getting a boat out of the water.

lmfao forgot about that one i guess :rolleyes: :)

It is rated for 26k, but I still use the e-brake too. Up here in the northeast if you don't keep using the e-brake the cables will sieze over time. They are a part of the safety inspection and some guys will fail the inspection for them not working.

I think they all need to be recalled. Mine quit working on my 3500 not long after it was new and GM would never fix it under warranty. The dealer charged me like 300.00 to fix them. I'd love to get a refund.

I found some more information that indicates that the change will be to the cable assembly, either a modification or a replacement. Car makers have used cables for emergency brakes for decades - how did GM screw this up?

Maybe the cable gets pinched....that bend behind the front wheel is pretty severe.

You should ALWAYS use the parking brake in a manual trans vehicle.

Tom :pig:

Big Blue's parking brake has been about effective as sprinkling sunflower seeds in front of the tire.

I don't even trust it to change front tires on level ground.

Well that recall covers me, but I have yet to get a notice.:confused:

Bring as many as you can to Emmett, ID; I will Adjust them ALL @ $300.00 each:grd: , parts and labor for repairs are extra. :exactly: Brake Adjusment is routine maintenance, an owner responsibility, just like changing your fluids. Repairs are warrenty items.

I'll eat the cost now, as my emergency brake is completely useless. I've cleaned and adjusted, and it will roll on the slightest incline.

How did you adjust it, if I may ask?

Idahofox

There are small holes in the backing plate to get to the star wheel which takes slack out of the brake assemble. These holes have rubber plugs in them. (or they should) One hole is toward the top, and the other side is near the bottom. I'm not sure which way to turn the adjuster. I adjusted until I felt some slight drag when turning the wheel, but apparentely not enough, as the e-brake still doesn't work.

The static shoe clearance adjusting Port (hole) should be on the Bottom, left and right.

Adjusting the static shoe clearance is correct. Both left and right must be adjusted the same, First.

If cable length has been adjusted and it's Wrong, the Auto/Slack Adj may not set up right.

There is a Auto/Slack Adj @ the pedel, adjust's the cable length. With out the vehicle moving, hold the release handle up and cycle the pedal from Fully applied to Fully released, hold foot on pedal so it doesn't snap back, 3 - 5 cycles, ( it's a ratchet, like a Come-Along). Does not matter if the Disk Brakes are applied, seperate system.

I believe if you let the pedal Snap Back, that will damage the ratchet in time.

Brake adjustment is a routine maintenance item, like changing fluids.

Hope that helps.

IdahoFox, oddly enough, on my '01, the adjusting hole is at the top on one side. The assembly is roughly upside down on one side.

6spd,

My Helms are 2003.

McRat's '04 & '05 is like mine.

Does the Cable enter the system Top/Bottom, like the ports?

If this miss led you I sorry, if it helps at all, Great.

Good luck with the project.

Are you guys taling about vehicles with 4 wheel disk brakes?? The pict above looks like regular drum brakes. 4 wheel disk brakes have a separate brake setup for the parking brake.

My truck is in the shop to have the parking brake replaced. It would not hold and there is no adjustment per the dealer. They say that the parking brake shoes are worn out. The truck has 76,000 miles. How can the parking brake wear out???

The shoes are $216.00 plus labor; total $527.00.

I will file a complaint and claim to GM about this. A brake pad can only wear out if it rubbing during rotation and it should not be wearing out. The dealer says there is supposed to be a recall coming out. The one talked about above is only for manual trans. They also said they have several of this a week and nobody understands how it be wearing out. He has another one besides mine.

Yes - this is for the 4 wheel disc brake trucks. The rear rotors are a combo rotor/drum using shoes for the parking brake and pads for the brakes. Stupid set up.

got My letter last night. going to dealer tomorrow.

I got my letter today.

Got mine today.My e-brake works great but my brakes suck.:confused:

Got mine today.My e-brake works great but my brakes suck.:confused:

ditto here

Got my e-brake fixed today. It actually works now!!! Never thought I'd see the day.

Finaly got mine fixed too.Had them do the free fuel filter while it was there.We,ll be going in for ABS recall in november.

Anybody have the part numbers for the recall? I'm very happy that my truck has never been to the dealership, and don't plan to start now!

im surprised to hear abuot so many people using the parking break!! i noticed come of you are in the colder portions of the country!!
I learned befor I had my drivers license to not use the parking brake unless you really needed to.( in cold weather) because you'd come out in the morning and not be able to move the truck cuz its frozen up(if ours actually could stop the truck)

personally i don't worry about it unless I'm on the boat ramp... just that added slowing effect(cuz it won't actually hold my truck with the 38"' tires) of the brake for the "just incase" factor.... in theory, maybe I'd be able to get to the truck before it was completly under water if the parking pin gave-way LOL...

****! I even used the damn thing when I had an automatic. I've got a buddy with a 2001 2500HD 6.0 liter 4l80 and he parks on a hill. Sounds nasty when he pulls it out of park. When driving an auto I always put it in N and apply the parking brake then put it in park. Guess I'm crazy!?

Has anyone ever come up with a parts list. My parking brake is terrible and I'd like to make it work properly. I've got the Allison, so I won't be getting a recall letter.

The right hand parking brake cable is part# 10362946

Is that the only part that they replace?

That's the only part according to my parts guy. Vent on - Took the wife's 03 Trailblazer to the dealership for some recalls and warranty work. They were supposed to spmily replace the passengerside door molding. It was coming loose. Simple task - right? Well they gouged the molding and hoped I wouldn't notice. They are now having to replace the molding again. An hour's drive for me again. They asked what they could do to make me happy. I told them I wanted the emergency brake cable handed to me for my 01 2500HD. They of course can't do that - safety reasons. Well if they cant replace a simple molding correctly, am I to trust my life to some moron mechanic that can't replace a door molding? My truck will never see a dealership - I can't afford to replace it when they screw it up. Vent off. I feel better now. I'm sure there are good mechanics, I have just never had the luck of dealing with one.

So, this weekend I'll be insalling my own emergency brake cable.

Does anybody know why you can pull the e-brake cable towards the back of the truck about 2 inches? In other words, I can sit next to my truck at about the driver's door, and move the cable toward the back when the brake is NOT on. Where is all this slack coming from? It feels like a spring is used in the pedal assembly to prevent excessive pressure.

Anyone have any thoughts? Is it part of some mysterious self adjusting mechanism like in our clutches?

mikek996,

That was the body shop!!!!!!! Went back Saturday and there were several flaws in the paint. Yet another wasted trip. Next question, will the paint actually match?

DMAX the slop in the cable is from the "low pedal effort " style of parking brake. It is coming out of the pedal assembly IMO that setup stinks we get a lot of complaints on it. A TSB.....

#01-05-26-001A
This bulletin is being revised to add models and model years. Please discard Corporate Bulletin Number 01-05-26-001 (Section 05 -- Brakes).
The vehicles indicated above have a "low effort" parking brake apply system. The design intent is that a low force on the park brake pedal will effectively apply the park brake. This was done so all operators can easily apply the park brake sufficiently to maintain the vehicle in a stationary position on an incline.
Owners should not interpret this low pedal effort as an indication of system effectiveness.
This park brake system is self-adjusting and there are no cable adjustment provisions on these vehicles. When a vehicle park brake system has been serviced and/or the brake rotor has been removed or replaced, ensure proper system setting is achieved by performing the following steps:
<LI type=1>Verify that the park brake shoes are adjusted to provide a clearance of 0.66 mm (0.026 in) between the shoes and brake rotor as indicated in the applicable Service Manual procedure.
Fully apply and release the park brake lever three times.
