After rebuilding the front calipers... the mileage went up 10%... quite a nice surprise.
After 10 year's of use, the pistons had a tar-like ring at the inner seal. The pads couldn't back off completely.

I found the samething on a 79 cj5 I use to have. It pays to check on your brakes a little more often. Especially at todays gas prices.

Back in the "good ole days", my friend's shop used to recommend bleeding brakes every 2 years. (Flush out the old fluid.)
I wonder if that would help prevent this tar buildup inside the calipers.

I was just reading a pamphlet (from a local auto parts store) about improving your MPG and it mentioned checking the brakes for sticky caliper pistons (or other problems).
Cool !

Don't know about the "tar" buildup, but I believe that DOT 3 can absorb water, so changing it regularly might prevent rust/corrosion. I thing the synthetic fluid (DOT 5?) does not absorb water, so it wouldn't have that problem, but it may change the pedal "feel".
Oh, if anyone considers changing from 3 to 5, I think you need to get the 3 completely cleaned out of the lines/calipers/MC. I think some people have flushed the whole system with alcohol.

Good point.
No corrosion inside, but it's like the fluid slightly melted the rubber components.
I'm pleased w/ the design 'Zuki used on the calipers. Polished stainless steel, instead of rough cut aluminum (ala GM). 80K before it hit the rub bars... wonder how long it'd lasted if they weren't dragging.
