Yeah, I'm full of questions....

2003 2500HD 6.0 4x4 crew Parking brake which I've always (in all my trucks) used everytime I put it in park, just don't wanna hold. I have been known to two-foot a time or two, but It was just for a second or two. Problem is, with a trailer on a hill, I don't want the weight of the trailer+truck pushing on my parking gear. So the Parking brake is always applied before shifting into park. Well the parking brake don't do much of anything. I think a cat would do a better job! I've heard this isn't the rear pads, but something that''s more of a pain in the butt. I need to have a good working Parking brake. Is this something a guy could do in his driveway or do I need to buy some beer and go to the local shop?

 

Thanks

After doing all 6 brakes on my Truck I noticed that the E-Brake Shoe assembly inside of the Rear Disc was pretty much worn and it would let my truck slide on any little incline. I replaced it with new Shoes and adjusted the tightener all the way back and it holds rock solid now. I don't have a trailer to test it but, I am confident that it will hold. It's a pretty easy job to do. Just take the rear wheel off, undo the rear caliper and Caliper bracing then pull the disc off. Inside you'll find your e-brake...

 

Hope this helps... :cool:

I had this problem on my 02 Z71 and it wasn't an issue with the pads they were well over 1/2 remaining. Responces from the dealer was its normal personally I think my problem was cable stretch but never did figure it out.

Mine holds very well now.

 

I previously replaced the parking brake shoes. Then, a few weeks ago, I put new rotors in back.

 

To adjust them, I backed off the nut on the splitter assembly all the way towards the end, then I adjusted the parking brake adjuster to where there was just a slight drag on the inside drum of the rotors.

 

I then tightened the nut on the splitter until the cable was taught and verified that the parking brake wasn't any tighter than I adjusted.

 

Now the parking brake will hold it from moving if I forget to release it and put it in gear.

 

 

Mine's a 2000 Sierra 1500. The rear rotors have drums built into the hub for the parking brake shoes (actually, shoe). There isn't any access for external adjustement, so adjusting them requires pulling the rotor, which necessitates removing the caliper mounting bracket (those bolts are something like 140 ft/lbs and require locktite on reassembly).

 

The parking brake shoe is a C-shaped assembly. Unfortunately, the gap in the "C" isn't large enough to slip over the axle, so replacing them requires getting into the rear differential, removing the c-clips, and pulling the axles (although I've heard you can stretch them enough to get them over the axle without pulling the axles - I don't know about that though).

 

 

An interesting "feature" I discovered is that, when the parking brake is set, the automatic headlights don't come on until you release the brake. Makes remembering to release the brake really easy at night.

Shouldn't have to mess with the diff to remove/install the parking shoe. It does, however, take a little finesse. If you start with one end behind the wheel mounting plate, you should be able to work it around the shoe to get it on. I've done it twice now on my Tahoe and haven't had to pull the axle. You should NOT have to bend the shoe at all either.

Thanks for the advice - I'll give it a try next time.

Hopefully, you won't have a next time with this :banghead: If it weren't for the faulty clip design, I don't thing they would have worn out at all. Or should I say they SHOUDN'T wear our unless you drive around with your parking brake on.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
