I am going to do the brakes on my 2000 4.0 HSE Bosch truck. The brakes are too far gone, will need rotors (discs) and pads for sure. The rubber seals that protect the caliper pistons are in sad shape, I am considering buying caliper rebuild kits and bleeding the brakes. Looks like the brakes were neglected, so fluid is likely overdue for replacement anyway.
Has anybody here had good/bad luck with caliper rebuild? I am going to buy the rebuild kit from Atlantic British, I don't trust the britpart kits. Any feedback on caliper rebuild kits is welcome. The calipers aren't all that expensive ($150 new, $70-ish rebuilt), the rebuild kit is $30. Should I just get the caliper? The brakes worked, but seemed sticky. The truck sat for a long time. The pistons don't appear to be rusty where it matters (on the working surfaces).
The dust shields ("disc shields") are both rusted and damaged, where can I get new ones? I can't seem to find them.
I am planning to bleed the brakes using a either conventional one-man method or using a vacuum pump (I got a mityvac). Some cars with fancy ABS require a scan tool to operate (open/close) the valves of the ABS system during bleeding. Factory manual for P38 does not seem to suggest that this is necessary. Are there any P38-specific gotchas that I need to be aware of? The Wabco is a rather unconventional hydroboost type off-road ABS system, so I would not be surprised if it had some unusual quirks.
Back when I used to own Discos I seem to remember needing a diagnostic tool for the brakes, but it was more than a few years ago and I forgot why I needed it.
