They fixed it by going back to old style drum brakes on half ton trucks (the only ones with the problem).

ok, I noticed that the parking cable adjustment was full on tight with no threads left (under bed). This was when I picked it up new in 2004. I asked the salesman about it and even started a discussion in the show room with all the Chevy people, no one knew why. When home, I backed it off, half way. Guess what, the park pedal grabed at the same spot. The "low effort parking brake" feature must be self- adjusting too. This is what is confusing. I noticed all other disc brake Siverados with cables mis-adjusted from the dealers; what gives? How about the design engineer's explation and diagrams?

According to GM-tech in an earlier post(maybe even in this thread), It is supposed to be that way. It is not mis-adjusted. The parking brake is not self adjusting in any way that I know of. The adjusters are under the rotors. You must remove the rotors to get to them. The system is nothing like the drum brake setup at all.

"Adjusters under the rotor", sounds like a Ford design, I kid. I loosened the cable ajustment(under the bed, front of the tire) till it slacked, then checked the pedal to see if it touched the floor. Next, I tightend the cable untill it put the pedal 2 inches from the floor. That left the adjuster at half way, or middle, not FULLY tight, with no threads left. So far so good, and all seems normal. Now if someone leaves the brake partially set, I would expect that only the amount of brake lining it takes to relive the setting would be worn away. In the old days if a driver left the park brake partially set the main shoes get worn out quickly, as with this new system only the parking shoes get worn. This problem sounds like one, that the Service Dept. CAN use to sell brake jobs to doubtfull people.

My yearly Texas inspection sticker is up at the end of the month, so last night I took it to be inspected. After handing over my truck 30 seconds before I hear the tech, “It won’t pass.” What the heck? My parking brake wont hold anything. He put the parking brake on, put it in drive and released the service brake, and the truck surges forward. Unbelievable.

The truck has right at 57K. I have searched and found a recall but you have to have a manual transmission to be a safety factor. Unbelievable. I guess GM says you need to rely on you paw to stop the truck from rolling on an incline.

Just ranting.

On my 99 silverado from new the pedal went to the floor the dealer told me it was normal.
The parking braKE HAS NEVER WORKED PROPERLY. Parking on an incline u have to fully rely on the parking pawl as the parking brake wouldent hold the truck.
i fitted new parking brake shoes with new rotors, i also fitted the larger clip to hold the parking brake shoe in place, but the shoe itself is only held in place with the hub on, the flimsy clip donr nothing to anchor the parking brake shoe in place.
Any way there is no point bi***ing about it as GM doesent care and to be honest they way they GM has being carrying on im not surprised.

I have a 99 silverado, regular cab ,long bed ,was 4 wheel drive,has auto and 5.3 vortek engine. one hundred and thirty

My parking brake still works great after 62k miles (03 suburban 1500 AWD). Will hold the car in nutral on a significant incline. I think a lot of you guys have got a lemon or something;.

I also love the no effort pedal and release. It is easy enough that I was able to convince my mother in law and wife to actually use the parking brake.

GM if you are reading this I ask you not to change the design at all.

My 98 Blazer holds fine. . . if you LEAVE YOUR FOOT ON THE PB. I just don't know anymore. Worked fine when I bought it over two years ago, then one day I was visiting family in a driveway I would not like to own in the winter, sadly disappointed. Good thing my pawl held and I was lucky enough to shift out of Park without help. GM, there is a lesson to be learned here.

My 99 suburban has 70K miles and I park on an hill. I set the brake everytime and it holds fine. the few times I forget I can't back the truck up until I release it. I never set if or years then once I took it to a tire shop and they said they could tell I don't use my brake becasue the pad was too high or low or soenthing and they adjusted it for me. they said you must use it to keep it adjusted properly. So now I use it.

Jefro-
I WHOLE-HEARTEDLY SUPPORT AND ENCOURAGE YOUR CALL FOR A CLASS ACTION SUIT, and will look into what the next step needs to be.

I agree completely that the Emergency/parking brake is poorly underdesigned, and GM should recall/repair these. My 02 Tahoe needed to have the Ebrake shoes replaced and adjusted in order to pass its first safety inspection at 2 years old because the brake would not hold the vehicle while in Drive. This is inexcusable. The only people who aren’t shocked by this is long time GM owners who have come to expect this level of “quality”.

You are free to initiate whatever legal action you deem appropriate, but I wouldn't count on success.

The parking brake is intended to hold the vehicle when parked. That is all. Don't forget that your basic 4-wheel hydraulic service brakes are split - with a seperate master cylinder section serving two wheels each. Thus, any single service brake system failure (other than a complete separation of the master cylinder from the vehicle or two SIMULTANEOUS hydraulic system failures) will still leave you able to stop the vehicle with the service brake pedal alone.

Only if this entire service brake system failed would one consider relying upon the parking brake for stopping (along with downshifting the transmission, of course). And, if your parking brake would not hold the vehicle stationary (or against engine torque in gear), it was do to insufficient maintenance or imporoper adjustment.

I own, among others, a 2002 Tahoe Z-71 and the parking brake mechanism functions fine, even after almost 80,000 miles.

I have the exact same truck and mine won't hold it off the park pall when I'm on an incline, it will add some resistance, but nowhere near enough.

01 K2500 Burb --- brake does not hold. ( rear discs, but with inboard drums for ebrake).

Root cause? Axle seals leaked into the e-brake drums. Too much oil on drums for them to hold.

If they sell the truck in Texas it must perform several safety checks each year. My truck did not and was finally fixed by GM. They repaid me after I started a lawsuit.

Hey guys and gals as far as the parking brake is concerned I think what is missing here is its called a parking brake in the old days it was called an emergency brake and was intended to slow you or stop you in the event of brake failure.

And according to the Department of Transportation, It still is intended to slow or stop the vehicle in the event of service brake failure, regardless of what GM wants to call it.

I was just going to post and ask why my park brake doesn't work on my truck, and I saw this thread.

Okay, I tried to skim the psots in this thread and I'm still confused . I always thought an EMERGENCY BRAKE was required on all vehicles by law, but it sounds like I don't have an EMERGENCY brake on my truck at all .

I have a 2003 Silverado 2500HD with the Duramax Diesel. It has DRUM brkaes on the rear, and the park brake goes to the floor when I depress it and doesn't hold the truck at all when I put it in drive.

I think I'm reading that you have to hold the regular brake to the floor when you apply the park brake, right? (I haven't looked in the owner's manual...I thought I knew how to drive a vehicle after over 35 years of driving!) I've never had to do that in ANY vehicle I've ever owned, and I thinkt hat's a STUPID design. It's kinda like GM saying that to turn left, you have to turn the steering wheel to the right. People get used to the way you use things in a vehicle, and this is a dumb change, IMO. I don't know of ANY other vehicle that requires you to do this.

So how do I stop this 3 ton "tank" if my regular brakes go out due to a total hydraulic system failure? I know the odds of that happening with a dual system are low, but it's still a stupid park brake implementation IMO.

I guess I need to go out to try my "park" brake, to see if it works the way the manual says it's supposed to. Will let y'all know.

I've had problems with GM on other issues with my truck. WOnder why they don't seem to give a damn about customers and won't address anything until you threaten them?

I was wrong about my rear brakes...they are disc. However, I tried to set the park brake like the owner's manual says, and it won't hold when I put the truck in drive. It does absolutely nothing. I have NEVER used the park brake since I've owned the truck. It sounds like others have had their brake wear out without use too.

I agree with the class action suit if this is really going on with everyone who buys these vehicles. At least we should see if we can get GM to recall them for repairs of the park brake. Is there anything going on? Even a letter-writing campaign to GM? Based on my last ordeal trying to get them to cover DEFECTIVE software, I don't think I'm going to try to get a dealer to fix the brake, because I'm sure they won't offer to do anything.

Mine holds the truck if I slam the sucker all the way down... It used to hold the truck with just a few clicks till I tried to take off like I stole it with the brake on... If some trucks have a P or E brake that hold then they all have to hold... Our suburban didnt hold either... We paid $700 and with 2 clicks it holds...The Parking brake has to hold no matter what!!!! If it holds my truck, our suburban, and our denali then it should hold yours too...

I have a 2000 1500 Z71 that I bought new in January 2000
The parking brake, a small drum in the rear rotor, has never worked from day 1
Now the disk brakes on this truck are the greatest ever
I get 80,000 miles on the rear pads and over 140,000 miles on the front
The anti skid is also much improved over the older system

I had a 1997 1500 2WD before this truck that went through front brakes pads every 30,000 and rear shoes every 60,000 miles

It just goes to show you, “it’s always something”

Well, here's another one.

I have a 01 1500 Ex-Cab. The parking brake has never worked. The one time I took it to the dealer, they stated it was normal???

The 4 wheel disk brakes are exception though. I went to 190,000 miles before replacing them, and when pulling the old pads off, found they still had at least 40% of pad material not used.

I wonder how many more miles they might have lasted?

I also have a 05, 1500 Ex-Cab, 4WD with drum rears. I've found the brakes on this truck to be somewhat inferior in comparison to the 01 when it comes to pure stopping power.

Personally, I would rather have the 4 wheel disk brakes with their crappy emergency/parking brakes, than the newer disk/drum arrangements.

72,000 miles and still holding like a champ!

For what it is worth I don't know why you guys think GM should be responsible for your parking brake working. If it isn't go in and have it adjusted. Making them responsible for it to me is like asking them to be responsible when your brake pads wear out or when your suspension goes oput of alignment.

Why not? Several folks have said that theirs has never worked since new. My truck was used, but the guy who owned it before me was a mechanic and always maintained it well. It's an automatic and I never use the "parking brake". The first time I tried it was when I hooked up a car trailer....it didn't do anything. I put the truck in gear at an idle, and it rolls. I thought it was something specific to MY truck, but after reading this thread it's obviosly a flaw in the design....they should issue a recall.

It's a defective design...why shouldn't GM be responsible? Where is my "emergency brake"? A diesel has very little compression braking, so what am I supposed to do if I'm cruising down Loveland pass and my brakes go out? Even my 56 Chevy has an EMERGENCY brake.

Not true IMO. You shouldn't have to pay to have a defective design corrected. There are more guys on this thread with p-brakes that don't work correctly than those that do. There's an obvios problem here.

Why do you not think you should pay to have your parking brake adjusted? Do you think GM should be responsible for realigning your car when your alignment is out? Should they be responsible when your fuel injectors clog or when your tires get worn bald and blow out? Parking or emergency brakes or whatever you want to call them have required periodic maintenence since they were invented. GM tries to help out by designing something that needs minimal adjustment and now they should pay for it to work forever.

I don’t think it has anything to do with adjustment

I have a 2000 year model half ton Silverado, as I posted above
Parking brake has never worked from its birthday (1-20-2000)
The water pump failed at 60,000
The automatic transmission failed at 80,000
I paid for these repairs as one would expect
It has a few electronic glitches, about once a year after I start the truck and am driving down the road I notice all the accessory lights are on and the auto headlights and dash lights won’t come on.
I have to stop and turn off and restart to get the electrical system back to normal
The Chevy dealer never could fix that problem either

If you have this year truck or a year that uses this design of parking brake and it works then consider yourself lucky and pipe down
Sorry if I sound harsh but I don’t think you know how to fix it
If you do, please share
Please don’t say “take it to the dealer”
Been there, dun that
I also have that driveshaft clunk when accelerating from a stop
That started at 16,000
