DOH brakes!
Well, knew it was time to work on the brakes and almost waited too long.
Camera was at work, so let's go with ye olde time fambly style typovision. Removed rear drums, pads have about 2mm left on the worst shoe, adjustor on the left is frozen up with dust. Not a problem, easy fix, new spring kit, clean everything, new pads. The adjustors jeep used are quite stout units. The old Chevy was stamped tin. That was unremarkable, just messy and time consuming with all the fiddly bits and springs. So now on to the fronts. Got the pads, noted that they were thick and got to thinking about just how much actually had worn off the fronts. Dropped the left side and the outside pad had about 3mm. Ok.. that's thin. Then I look at the inside pad. BUGGER! it only has 1mm of surface left! (glad they were molded and not riveted) sheesh! Left side was about 3mm on both pads. Drained out almost a full brake reservoir when pushing the pistons back in. Guess I should have bled them out then, but last time I tried that it was one hell of a mess. Easier just to squeeze the fluid back up. Now all I need to do is flush the system out. This time I'm going to pay a good local mechanic to flush the brake system. It's just too much of a pain to do it solo, even with a vac bleeder. -- DougW |

Make sure your slider pins are corrosion free. Uneven wear between inner
and outer is a sure sign of problems.

No corrosion, but the little boots were showing cracks so it's time to get some replacements. Did see some wear on the surface where the pads ride the top ledge. About 1mm of depth and 1/2" wide looked machined. Don't remember if that notch is stock or not, been too long since I did brake work. Used regular brake grease on the pins. Probably should use a lighter grease or silicone, but that's all I had. I just flat let the pads get too damn thin. 2mm of difference isn't that much over the lifetime. Thanks for the hint though. Think I'll get a new set of pins and gaskets, or at least gaskets. -- DougW |

The auto stores sell little packs of the special high temp, silicone
based grease for this application. Usually in a rack near the cash register for $.99 or $1.29. Well worth it. I live in the rust belt, had to do a 9:30 PM run to the dealer in the middle of a snowstorm to get new pins (and new emergency brake cables!) to get the brakes to quit grabbing.

Sure is, you get your buddy to do it, that's why you start any such job by getting a keg of beer, didn't you know that? ;-) NOTE: Barbeque works well also. |

It's one way of doing the job, you basically push the old fluid out and refill from the reservoir instead of having to suction off fluid when you push the pistons back in. It's much easier to push the piston back in also. Your basic hand pressure is enough. -- DougW |
