Yeah, I pulled both drums to see if the shoes and drums were worn, and there was no leaking.

Also possible you got a defective master cylinder. It happened to me once before.

I bled it again today. I put another two quarts through it. It didn't make much difference. I've thrown away about $70 just on brake fluid, so I'm going to stop for now. There's got to be something else wrong with it. It's not leaking anywhere though, so I don't have the slightest idea what it could be.

One trick for the bleeding is if ou use a small fish tank hose into an old break fluid container, you won't lose as much

I replaced the master cylinder again, and re-bled the whole system, this time making sure the hose on my bleeder ran above the bleeder valve. There is NO air coming out of the system anymore. It stops now, but just barely. Itís driveable, but not to the point where I would feel safe driving it on the highway.

Do S10ís and Blazers just have really horrible brakes? Is it not possible to make it stop reasonably?

Just a thought. What age & condition are the caliper to hard line hoses ? Maybe they are the culprit for the spongy feedback. If not maybe a replacement ABS is in order.

Thatís a good point. Theyíre in good shape, but I assume theyíre original. Iím going to replace the calipers and wheel cylinders, and Iíll look into getting steel braided lines to replace the hoses with. Right now though, it still seems like the problem is air in the lines. I have put about 8 quarts of brake fluid through it though. The only thing I can think of at this point is that air is getting in through the ABS unit.

Hey Steve, just came back and reread your journal again since you've been great about following and commenting on mine.

Glad to see you've been making some progress, sorry about the brakes. . .like me and my transmission problems.

I also think it sounds like you have a tiny pin hole that's leaking somewhere. On my 88 C1500 the hard line to the rear was rusted out. Possible yours is just starting to go?

Have you checked the bleed screws too? If they're boogered up could let air back in while trying to bleed. Did you ever try the vacuum bleeder?

One other thought too. . are you absolutely positive you got the correct master cylinder? I'm not sure of all the brake set ups that were on these trucks, but I've seen issues with people getting a master for 4 wheel disc brakes, when they have drum brakes in the rear, or vice versa.

Hope you're able to figure it out soon if you haven't already.

Iím pretty sure I have the correct master cylinder. I replaced it a second time, and itís better. I can drive it now (I drove it to work today with no problems.) But it still doesnít stop like it should. I bought new caliper pins because the existing ones are rusty, so hopefully that will help reduce noise. The main thing that I need to do is get the air bled out of the ABS unit, and since we likely wonít get any more measurable snow until fall, Iíll have to find another way to get the ABS unit to activate so I can bleed it again. Iím sure there arenít any leaks because my fluid level is staying consistent.

Iím the next few weeks, Iím going to start sanding the rust on the roof and find a color-matched paint for it. Iím also looking for someone locally who can rebuild the steering box. All of the companies that sell rebuilt steering boxes have pretty terrible reviews, so Iím nervous about buying one.

The tie rods I installed in December are already shot. The boots cracked wide open and leaked all of their grease out, so Iíll be looking to replace those too.
