WJ brakes
Hello!
The front passenger side brake on my WJ started to smoke last week.
The passenger side rotor was not cherry red but it was getting there
as I could feel the heat several inches away from the wheel. There
were bits of glowing/smoldering ash falling from the caliper. The
driver side was fine and was no where near as hot as the passenger
side. I had been riding the brakes in normal commute traffic.
So I bit the bullet and swapped out the Teves calipers with ones made
by Akebono. I was surprised at how easy it was to swap in (no fluid
in the new calipers).
When I took a closer look at the caliper that was smoking, I saw
that the rubber boot for one of the pistons had partially burned off.
This explains the smoke and the burning rubber smell. The brakes
were in otherwise good condition. No warpage yet on the old set of
rotors and while the inboard pads were worn away more than the
outboard ones--typical Teves on a WJ--there was plenty of meat left
on the pads and they probably had another 45k worth of meat left on
them. The driver side caliper was in perfect shape from what I could
see.
My question is WTF could have happened that would cause this?

The rubber boot is there to keep grim out of the ajustment bolts, those
aren't pistons, the pistons are in contact with the back of the inner
pad and are obviously getting stuck closed when you brake.
Unless you are actually meaning to decribe the piston, and you mean the
rubber seal around it, where it meets the caliper.
In any case you did the correct thing; replace the caliper (make sure
you greased the adjustment bolts a little).

In all seriousness, leave a little more space between yourself and the
next car and you'll never "ride the brakes" even in an Automatic...
This just happens to be the primary cause of "stop and go" traffic in
the first place... people who think they'll actually get home faster if
they CONSTANTLY speed up and get on the rear bumper of the car in front
of them, only to slam on the brakes. Causing a gigantic chain reaction
with all the other lemings, leaving no room for people to merge or
change lanes. Causing other people (like myself) to wonder how in hell
these commuters could spend 2 or 3 hours of their lives each day in rush
hour; NOT FIGURING OUT that a constant steady 25 MPH, is MUCH MUCH
better than 15 seconds of 35 MPH followed by 30 seconds of DEAD STOP.
Sorry nothing personal... it's a pet peave.

Yes. You can see the piston's resin surface under the burned away

I do think that I leave enough space between my and the guy in front,
maybe too much--the problem I get is the guy in the next lane over sees
the opening as a invite to cut in front of me--which would be perfectly
fine if they did not always have to slam on the brakes once they are in
front of me. I now have to brake to a) not hit him and b) to give more
space between me and the guy who just cut in front. Then, repeat with
the next yo-yo that's one lane over...
#Sorry nothing personal... it's a pet peave.
It's mine as well.
Back to the question at hand: If riding the brakes was the cause, then
I should have seen issues with both sides, correct? Only one side was
getting overly hot--the other was "normal" in that it was warm if I stuck
my hand near the rotor, but I did not feel heat on my legs when I was
standing next to the wheel well.

Yes. You can see the piston's resin surface under the burned away

I do think that I leave enough space between my and the guy in front,
maybe too much--the problem I get is the guy in the next lane over sees
the opening as a invite to cut in front of me--which would be perfectly
fine if they did not always have to slam on the brakes once they are in
front of me. I now have to brake to a) not hit him and b) to give more
space between me and the guy who just cut in front. Then, repeat with
the next yo-yo that's one lane over...
#Sorry nothing personal... it's a pet peave.
It's mine as well.
Back to the question at hand: If riding the brakes was the cause, then
I should have seen issues with both sides, correct? Only one side was
getting overly hot--the other was "normal" in that it was warm if I stuck
my hand near the rotor, but I did not feel heat on my legs when I was
standing next to the wheel well.
