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.

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

Yea, I pulled them out and cleaned/lubed them. 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.

I just push the pistons back in and put the new pads on. Why do you open
up the system? Just the way I've always done discs, never had a problem.
