    how to PM rear brakes on a '99 C3500?

    Thanks. It's just an old Canon PowerShot SX10. Their current models are even better. I got it for my son because it's simple, with one non-removable lens and an electronic viewfinder so it has no mirror flapping around. He uses it in automatic mode, and takes nice pictures. The lens has a...

    how to PM rear brakes on a '99 C3500?

    Thanks! To drain the gear oil, I remove the diff cover, right? Is there anything I should do while I have the diff open? Is there a way to flush out the junk before I close things up and put in new oil? Thanks, -jpg

    how to PM rear brakes on a '99 C3500?

    Right. I ordered new bearings and races. For the record, here are some photos of the bearings after nearly 175K miles. They do show some wear. I'm guessing that this means I should change the diff lube while I'm doing all this. Should I be reading any other information from these wear...

    how to PM rear brakes on a '99 C3500?

    I got the bearings out and clean. The outer bearing has a couple of rollers with small rough spots, about 3 spots total, each about the size of the head of a pin. They are indentations into the roller, not protrusions. If I run my nail over them, I can feel roughness, but running a fingertip...

    how to PM rear brakes on a '99 C3500?

    I used an entire can of brake cleaner on the outer bearing, and it still feels gritty when I rotate it. I need to remove it and clean it more thoroughly. Unfortunately, it seems I do not have a tool that can remove the snap ring in the picture below. My biggest pair of needle-nose pliers...

    how to PM rear brakes on a '99 C3500?

    I pulled the seal using a flywheel puller, and cleaned everything up with brake cleaner. The inboard bearing looks good to me. Should I also pull & inspect the outboard bearing? It looks like a snap ring is holding that bearing in place. Anything else I should do before greasing the...

    how to PM rear brakes on a '99 C3500?

    OK. Here it is with the proper shoes. The bar and lever no longer bear on the center of the backing plate. The shoes are now tight up against the plate. Amazing how much better this works with the right parts! I still can't find where to adjust the parking brake cable length. The last two...

    how to PM rear brakes on a '99 C3500?

    I took another look at why my brake pads don't rest against the backing plate. The brake bar and parking brake lever bear on the raised area of the backing plate before the shoes touch. I looked at my photo of the backing plate before I cleaned it, and it shows no wear in the areas under the...

    how to PM rear brakes on a '99 C3500?

    I had a chat with the Chevy parts guy this morning. The part I ordered is exactly the part I have, so my problem is not an incorrect parking brake lever. In the photo below, I have the brake bar installed. You can see how the shoes are held apart at the top. My parking brake pedal is in the...

    how to PM rear brakes on a '99 C3500?

    I have 3 cables. One goes from the pedal to a joint beneath the rear passenger door. One goes from that joint to the left rear brake. The third ties into that rear cable about 3-4 feet behind the joint, and runs to the right rear brake. So any of these cables could be wrong.

    how to PM rear brakes on a '99 C3500?

    OK. If the lever definitely goes behind the shoe, then either the cable or the lever is wrong. I pick up a new lever from the dealer in the AM. We'll see if it's different than the one I have. I suppose the cable from the pedal could be wrong also. I'm only short a couple of inches...

    how to PM rear brakes on a '99 C3500?

    Here's another thought. The brake lever prevents the after shoe from sitting flush against the backing plate. Could it be that the lever should be outside the shoe, rather than behind it? The manual drawings are ambiguous on this point. That's not how it was installed when I opened up the...

    how to PM rear brakes on a '99 C3500?

    My brakes match the duo-servo drawings: except for the parking brake lever, which matches the leading/trailing drawings: You can see the latter image has totally different parts than my photos, except for the parking brake lever.

    how to PM rear brakes on a '99 C3500?

    The plot thickens. I looked closely at the '99 C/K GM Service Manual. It talks about 2 kinds of drum brakes, leading/trailing and duo-servo. Based on the drawings in the book, it looks like I have duo-servo brakes except for the parking brake lever, which looks like the leading/trailing...

    how to PM rear brakes on a '99 C3500?

    Does the position of the parking brake lever look correct for when the brake is released? I was thinking perhaps it should be much further to the right... Thanks!

    how to PM rear brakes on a '99 C3500?

    OK. Switching the springs helped a lot. Now the front shoe lies flat against the backing plate. Thanks! While I had things apart, I reconnected the parking brake cable at the joint below the passenger side door. Here's a picture of that joint: Now the parking brake lever arm is keeping...

    If I understand you correctly, the adjuster has been closed tbe whole time. This is the screw with the knurled knob between the bottom of the shoes, right? It's closed in the photos, right? Thanks again for your help. -jpg

    how to PM rear brakes on a '99 C3500?

    I did attach the brake cable to the arm at the beginning of assembly. There is a joint in the parking brake cable beneath the rear passenger side door. When I was struggling to get the brake shoe nails in place, I disconnected that joint in the cable so I wouldn't be fighting the parking brake...

    Here is the next chapter in the continuing saga. I treated the rust with wire brush, naval jelly, rust reformer, and rustoleum. When I came into the house after wire-brushing the rust, my wife told me I looked 10 years younger. The rust dust covered the gray in my hair... I reassembled the...

    how to PM rear brakes on a '99 C3500?

    I just went through my newly-acquired service manual, and these "actuator rods" do not appear in any of the exploded diagrams of the brakes or the wheel cylinder. The index mentions a number of actuators related to power door locks etc, but not related to brakes. The manual uses the term...
