I'm preparing to replace my '99 C3500 front brakes and rotors. I called the dealer's parts folks, and their disks come with a new hub attached. Evidently GM doesn't expect their mechanics to separate the disk from the hub.

Thanks! I'll add a coat hanger to my kit. Now that I've done this once, I think I have enough length on the back to make your approach work. Though I'll also need to add a shovel... I mounted them on the outer dually, so there is no way the chain could reach the brake line. Also, when I...

Our property has a little-used unpaved drive that traverses a fairly steep slope. I use this drive when unloading one-ton pallets of the wood pellets we use to heat the house. I have to time my deliveries to avoid driving up the hill when it's wet and muddy. This year, I got the timing wrong...

Update: When I used this jack the fourth time, to lift the rear passenger side up off the blocks, the main support beam of the jack bowed. This 7000-lb-rated jack is permanently bent, from lifting one wheel of a 6000-lb vehicle. HF tells me I'm outside the 60-day warrantee period, so I'm out...

That's what I was thinking. The nastiness is on the side of the teeth that are loaded in reverse. The sides that are loaded going forward look clean. Thanks! -jpg

Cable/equaizer thread mismatch. AARGH! I finished the RH brake & bearings. I mounted the wheels before crawling underneath to replace the parking brake cable. We lost an EMT last week when his vehicle slipped off the jack stand and crushed him. He was the Fire Department's master mechanic...

Differential pix Hi folks. Here we have photos of the differential. I cleaned out the old lube & gasket, treated the rust on the cover, and reassembled with RTV. I decided the fill plug would be "a bridge too far", so I'll just pour the lube down the axle tube while I have the axle out doing...

Thanks guys. I took the old line to the store to use in selecting a compatible replacement. Then I used the old line as a bending template, and put a loop above the diff as suggested. Here's a suggestion for other newbies like me. Tape the fittings to the end before you start bending. It's...

I thought rebuilding the second hub & brake would be easy, now that I've done this before. This time, I have all the tools, parts, and instructions beforehand. Unfortunately, this time the brake line fitting was frozen to the line, so the line twisted as I turned the fitting. Bummer. I went...

Here's a point that will be obvious to those with experience, but might be of value to other truck newbies like me. When I re-mounted the wheels, I carefully torqued the lug nuts to 140 ft-lbs per the manual. After driving about 10 miles, I re-torqued them. Many of the lug nuts rotated...

Too much corrosion on the passenger side. I was afraid it would shear before it opened. I'll bleed both tomorrow after I replace the cylinder and other parts on the passenger side.

Thanks! I flushed the brake fluid. The old stuff was very dark :eek:. I suctioned the fluid from the reservoir, wiped out the gunk at the bottom, refilled with fresh fluid, and bled until I got clear fluid. I'm back on the road, though still without a parking brake while I wait for a new...

One side at a time. I don't have the best workspace. I need to turn the truck around to work on the other side. I had planned to turn it around with working parking brakes, and to bleed the brakes when I'd finished the second side. Now I guess I'll turn it around with no brakes, very gently.

yes. it passed through the equalizer to the parking brake lever inside the drum.

I think perhaps the old shoes were worn enough to make a difference. I could get the drum 1/3 of the way over the new shoes. The bar dislodged with a dramatic ping when I backed up, about 20 miles after the parking brake repair. It wasn't bent at all. It's possible I backed up with the...

Once more into the breach... I still don't understand how loosening the threaded rod on the passenger-side cable can loosen the driver-side cable, but you guys and the manual say it does, so I gave it a shot. After repeated sessions with penetrating oil, and then with heat, I succeeded in...

I must be missing some part(s). The cable passes through the stamped part to the driver's side rear brake lever. On the far side of the stamping, the cable passes through a black sheath, which is just visible on the far side of the stamping in this photo. The stamping bears on that sheath...

I installed the new bearings and seal, carefully cleaned off the axle, and I can't get the drum more than 1/3 of the way over the new shoes. The adjusting screw is fully closed. The parking brake pedal is released and all the way up. The parking brake lever is all the way aft. I posted...

That is *so* what I wanted to hear. Reassembly starts tomorrow! Should I do something to seal the metal, while I have it open? Thanks, -jpg

OK. I removed the bearings and races from the hub. When I picked up the replacements, I brought the old ones to make sure they matched. They did. Then I cleaned out the old oil from the hub, and I found some pitting from old corrosion in the area just outboard of the inner race. Photos...
