Brake Opinion
This caliper is off of the front drivers side, I though one of them was leaking. This is my first time I have ever worked on brakes so let me tell you what I think I see and I would like to hear from you guys with what you see.
The caliper has been sleeved and the sleeves are in decent shape, It looks like they dimpled the caliper in order to hold the sleeve in and these dimples are causing the lip seal to leak in fact one of them is really bad another one looks like it was squared off a little.
If I grind the lip seal edge on the caliper down to make the seat round is that going to cause me other problems? Should I so a little polishing of the caliper sleeves?
Another question I thought when the caliper's are sleeved you can use an o-ring instead of the half ring that I am seeing.
Any input would be appreciated.

Use a Dremel with a small grinding (round) tool to smooth those stake marks in the bores. The sleeves should have been press-fit and/or held in with Loctite, so they shouldn't ever be loose. If you smooth/remove those stake marks and the sleeves are loose, replace the calipers as they were sleeved improperly.
Otherwise, smooth the stake marks out and rebuild as you had planned. The small loss of retention area for those dust seals is a minor issue.

Ordered the new seals from Wilcox (Thanks guys) and I am going to use the dremel to work the dust seal and re-install, I am going to re-due the other front caliper just to make sure they are both done correctly.

If you had a leaker do all 4 and clean the master cylinder...You must avoid water forming rust in the brake fluid...That's basically what tears the seal up [the rust}
Brake fluid attracts water and then turns to rust cutting the seals...These cars today set too much. When used every day the rust issue was minor...
vicious cycle, and your better off using OE type replacement parts...ie Wagner, Eis, ect.
