Ok, so I cleaned up the front calipers this morning a bit, they look almost good (still have the factory coating Im after). Im thinking Im going to want to get them blasted and recoated though. My question is do I leave the calipers complete (with everything still attached) then have them blasted and coated, OR do I take everything apart then do it?
I need to figure out a place in town that will Zinc coat the calipers and carriers, but i wanted to ask before I did anything.

Lastly, how do the pistons come out of the front calipers? I know the rears unscrew, but Ive never taken apart a caliper in my life. I was gonna post pictures but the camera batteries are dead

Put a block of wood in the caliper to protect the piston and then use compressed air through the hole where the hose attaches and blow the piston out.

For the cost/effort etc of blasting, coating and re-sealing it may be almost as cheap to buy new or rebuilt calipers. I recently got new ones for my '86 Coupe for $75 CAN each.

Talked with a few people about new calipers, getting prices on Tuesday for those.

We'll see what the cost/benefit is going to be and if its "worth it" IMHO to get new ones.

..if you buy new or rebuild, should replace the slider pin boots while you have the calipers off...cheap insurance.

I actually had a tough time getting the new boots on today, but after I figured it out with the first one the other was cake.

The person who told me about the calipers said he could get OEM ones for a super price (including carriers), so we'll see.
