Cracked piston boots? Popped out a piston? Run lots of track days? Then this rebuild kit is for you! Contains parts to rebuild the seals on one set of non-Brembo 4 pot calipers- 8 piston seals, 8 piston rings, 8 piston seal retainers, and a packet of grease.

Price:$25.00

This is the complete kit I used to rebuild both calipers.
Great- that's the one I got

Fair enough, thanks for the great write-up.

Thought I would bump this up right before winter strikes IL, seeing that I need to rebuild my OEM '02 WRX front calipers (used on my '00 Impreza L Sedan) due to a seized drivers side piston.

Purchased the rebuild kit from my local Subaru dealership, cost $30.00 and it includes outer dust boots, inner seals, and lube for rebuilding both front calipers.

Here we go again

don't split them- no need to- the only thing to check is the seals/boots/pistons- that can be done w/o splitting them- these is a step by step tutorial on rebuilding the calipers floating aorund

What bolts are missing on your calipers? Can you provide us a pic of your calipers?

There should be no need to split the 2 caliper halves apart unless one side was damaged and your replacing it with a new half. I believe if you do split them apart there are seals connecting the inner passages which may then need to be replaced...and I don't know of any vendor that sells those.

This how-to is retarded. You do not put grease on piston or the inner seal - this contaminates the brake fluid with grease. The OP could have added some to brake master cylinder for a good measure as well

The grease is just to be used on the lip surface of boot where it contacts the piston. A coat of brake fluid should be applied to the seal, piston and the cylinder surface before the assembly.

Thanks for chiming in 4 years later...
At the time there was little info on rebuilding 4-pots and mis-information out there as well. This was the best I could do since no one else stepped forward to assist.

EDITED Thanks to unclemat

This is a great thread, sorry to take this O/T but would this method work for calipers that are nearly 100% seized or is that when you would need to split the halves?

I have 2-pot Version 1 WRX calipers that need replacing or rebuild. If anyone has any leads on a kit for that I would be greatful

Awesome tutorial jaygold

Yeah, scary that in four years noone pointed this out to you.

C'mon, anyone who does ANY brake job should know that grease - or for that matter anything else that could be contaminant - is not to be put into the brake fluid. Otherwise it's best to leave the job tthe car to a pro. If you're unusre about what you're doing don't post how-tos. It does more harm than good.

I agree, rather enlightening...and this why I placed the write-up on here; to share and learn since it was the first real 'brake job' other than swapping pads/rotors I completed so give me some credit.
It's been edited with your input and the only folks rebuilding the 4-pots at this point would be those with older JDM versions and '06 TR's-on which probably don't require rebuilds just yet unless tracked hard....so let's move past the criticism already.

I would be hard pressed to find out the pistons are sized drastically different than later models, but ya never know with Subaru. Apparently Nissan 300ZX 4-pots are similar and those go back to 1989 models. I'd hit up a Subaru specialist on older gen JDM models to find out the info your looking for just to be certain. Maybe the folks over at RS25.com have some info on those calipers and rebuild parts/part#'s.

I found the posting helpful for rebuilding my RacingBrake 4 pots though they have no boot. I didn't use and grease, just some brake fluid as I knew better
