Can someone confirm I'm understanding correctly that the entire 14362008 kit will work on the 88 rear caliper EXCEPT the large external accordion dust seal that covers the outside of the piston immediately adjacent to the brake pads?

In other words, if the huge outside seal that moves and stretches in and out with the piston movement, is in good shape, can I buy just the 14362008 kit and use all of the included seals except that one biggest one? And I would only need the 88 specific kit (14362031) if that external piston accordion seal is torn?



You should definitely get both kits and replace everything while you're in there, after all, the kits are cheap! You definitely don't want to have to do this twice. The first time I inspected those accordion dust seals I thought they looked good, but by the second caliper I realized they were actually cracked so I had to replace both. It can be very difficult to tell if they're bad or not so I'd highly recommend replacing them. IIRC, the main seal between the OD of the piston and the ID of the caliper housing is different as well.

Another useful guide with pics that are 404d... Any chance of re uploading them?




Any recommendations for a reliable image hosting site that I can upload them to as an alternative? I can leave the PIP ones in place too, but it wouldn't be a bad idea to have an alternative link for each one for instances like this.

Most other sites have worse problems.
1 is many Links to them expires after a few week to months.
Others are sold/bankrupt or X co thinks cost to much money and servers go down permanently and with little warning.
these are why many archive treads had dead img tags and Cliff make PIP

Posting for a bump and a reminder to order seal kit this weekend.

Bumping this one back up again since I had some people recently asking for the link.

Hey...I am doing one of these right now....But the problem is, the thrust-washer that goes on the inside of the caliper on the parking brake shaft is worn pretty badly....Would there be a possible replacement source...?

Any info would be appreciated!

Had someone else recently asking for the link to this thread so I figured I'd bump it back to the top.

After 4 car seasons and about 10k miles, my calipers are still fully functional and leak free.

Done this repair a few times on the original '87 calipers and had to do it with a remanufactured (ie "new") Seville caliper.
As Ogre point out, this is delicate work that doesn't always pay…
Got to be ultra clean and I would suggest to use silicon rubber grease for the reassembly - it helps with the self adjusting system allowing the inner piston to turn more easilly on the backstroke, thus taking up the play. Otherwise you end up with a resealed caliper thats works more or less fine under hydraulic pressure, but doesn't do handbrake adjustment anymore. Terribly frustrating!!

I could not find any up to date info on the inner piston umbrella seal. Does anyone know about this potential Pontiac 6000 o ring seal that works for the inner piston seal on an 88 Fiero?

If a Google search is any guide, this appears to be a solution that went out of stock long ago ...
