I apologize ahead of time for any typos or errors, I'm doing this on my phone, and it has not been easy to do.
I have searched and didn't find any direct threads for a write up on rebuilding the front calipers. I did mine for 4 bucks a side I have searched and didn't find any direct threads for a write up on rebuilding the front calipers. I did mine for 4 bucks a side, have a friend discount at Napa.
I'm skipping straight to the caliper, as removal should be pretty ovbious for anyone that has worked on their brakes before, and if not its covered extensively under searching. The only thing I recommend is leaving the pad bracket attached to the car and just remove the caliper itself.
Here's the basic caliper.
First step is to get the piston out of the bore. Easiest way is with an air compressor. You can do it using the cars brake system, but its gonna make a mess, fair warning. Use a rag on the other side of the caliper, as when they come out, they fly. I got my finger between the piston and the caliper on my first caliper.
Piston out.
Then remove this seal. Just grab and pull.
And remove the inner seal, using a small flat head gently so you don't score the metal
On the new seal, this is the lip that seats on the piston, worry about that last
Next clean out the bore and clean off the piston. Use a small wire brush to remove any rust from around the seal lip on both the bore and piston. Once clean, using brake fluid as lubricant, put the square seal in the bore, and lubricate the piston.
Once that's done, push the piston through the seal, and have the bore end hanging off the back end of the piston.
Time to seat the seal in the bore. I did most of it by finger, but you can use a small flat head BETWEEN the bore and seal to help push it in places its not fully seated. Don't push on the seal itself cause you can puncture it.
Now you may get lucky when pushing the piston back in. On the drivers caliper I had to use a c clamp and small flat bar to push it in, and the other side went in by hand. Either way you do it, make sure it goes in square, or it will bind up and you'll have to blow it back out.
As it goes in, the piston seal will seat itself.
And the finished product. The seal should not stick out past the flat lip of the caliper. If it does, blow it out, and try again. If any side is sticking out, even a little, the seal didn't seat and it will either leak or fail under braking. That's why I recommend using the small screwdriver to go around the lip.
When putting things back together, make sure you have the washer between the brake line fitting and caliper. Also, clean the slide pins and give them a really good coating of high temp grease.
If someone can shed some light on which slide pin belongs where, I would greatly appreciate it. Both sides were in different locations, but considering the way they look, they must be location specific.
When its all put back together, bleed the front brakes. Before you bleed them, slide the calipers back and forth to make sure your slide pins move freely and aren't bent. I had a dragging issue, coating my wheels in dust in just a few days, this took about 25 minutes a side from start to finish, and fixed my issue completely.
got an update for everyone on the 2 slide pins. one is marked "G" on both sides, then the others are "L" and "R" respectively for each side. just match the "G" stamped bolt with the "G" stamped hole on the calipers. and remember, grease them up every time you take them out.

Your calipers look to be in great condition too. mine were pitted on the piston a little and in the back of the bore, I cleaned the bore up good with brake cleaner and got all the sludge and crap out, took out the bleeder screw and cleaned/reamed out the passage thru it and the hole with little drill bits and greased the threads, and polished the piston with mothers polish, which broke up the varnish crap and brought it back to a mirror finish then cleaned it and the caliper with denatured alcohol to get rid of any petroleum residues, and flushed the system with D.A.. all the boots and o-rings were slathered in synthetic brake grease;wire wheeled the notch where the boot seats etc etc. Feels good knowing you did that shit yourself and your car stops eh
