All parts from an '88 4runner, should work on trucks also. I'm located in eastern PA but travel alot so I might be able to deliver, or PM me your zip and I'll get a shipping quote (I'll only add actual shipping cost)
Master cylinder worked fine when removed a few months ago, was only a year old
NAPA new = $75 - get it for $30 + shipping
Brake calipers - both worked fine when removed a few months ago, 1 is only a year old, pistons push in nicely on both (not seized), come with nearly new semi-metallic brake pads (2,000 highway miles on them) Should work on 84-88 4runner/pickup and 75-90 landcruiser according to my source - check the 2nd pic to verify what is on your rig
NAPA reman w/ pads = $100/both - get them for $50 + shipping
not sure if this is what's on your truck? Look for this "S12-8" casting mark on the outside face of the caliper
Brake rotors - 1 newer than the other, neither are warped, both are above minimum thickness and neither have much of a lip around the outer edge
NAPA new = $30/ea - get them both for $20 + shipping
I also have a rear proportioning valve that I think if fine, I'll toss that in for free (minus teh long rod that comes out of it) on any of the above.
