I've got an 86 944 Turbo that I'm resorting. I'm in the process of replacing the pads, rotors, rebuilding the calipers, draining the brake fluid, etc. Since I'm going to this much trouble what's a little more work to remove the calipers and get them powder coated.

Are there any rubber seals inside the calipers? It looks like the fluid transfers from one side to the other via hardline at the bottom of the caliper and not through the caliper. I've seen some youtube videos on brembo calipers that are off newer cars that have a some what different design that have rubber seals on the inside but they don't have an external hardline.

I'm going with a "yes" on rubber seals in the caliper. You can track down a rebuild kit and rebuild them after powerdercoating.

It will have a internal seal the piston rides in and then a outer dust boot seal...4 of each for each caliper so 8 seals to replace on each caliper. You can pop them out with an air compressor (careful!) and replace.

DON'T PC THE CALIPERS.....

Paint them if you DIY, or hard-bake finish them if you can, if you need our help we can do them for you as well....

You do some great work and I like the way you sign your art

When I did mine I separated the two halfs of the caliper, replaced all the rubber parts and the two ss plates and bolts holding them on. Then I painted with a caliper kit I bought from Por-15.

Note: getting the bolts out that hold those ss plates is a pain and you will likely need to use heat and lock-jaw plyers. Separating the halves helps in getting the whole caliper painted and when the ss plates are back on the calipers look stock again. I notice WD ^^ simply paint over the plates, connecting piece and caliper bolts, I'm not keen on that. The Por-15 caliper paint is very good stuff, I'm happy with the results

Wheel dymanic.. What do you charge to repaint Front and rear calipers?

Rubber seals. they're made to take a LOT of heat.UV cure powder coat is cool.

I should have been more clear in my question. I knew that there was rubber seals in the pistons but wasn't sure if there was anything inside between the two halves. I realized after the fact that the videos I watched on this were on calipers where the fluid went from one side to the other through the frame of the caliper and not with the hard line that runs between the two sides on the 944.

I'm doing the powder coating because it's not going to cost me anymore than the cost of the powder coat. I have a friend that does a lot of small part powder coating.

Breaking the two halves a part has proven to be quite a difficult task. I have another friend who says he has done this task several times so I'm going to take the calipers over to his shop and then to my buddy that powder coats.

Magk944, Did you torque the bolts connecting the halves to a specific Ft Lbs?

Wheel Dynamics

We currently charge $160 ea., strip, paint decal, clear coat and hard bake finish. We do not offer any sort of rebuilding services right now.

If you want to have us remove the old script (grind and smooth) then it will be $25 more per each.

We also shoot other colors as well.

Price seems very reasonable - can you do Ultraviolet?

Standard torque values for the new grade 12.9 bolts I used. There are two sizes of bolts on each caliper M8x1.50x80mm 33lbft and M10x1.50x85mm 63lbft, both partial threaded. At least that is correct for my 86T calipers, cannot vouch for others. Factory manual and technical bulletins are not very helpful, this is all they have:

The 4 small allen screws in the middle of the caliper are the biggest pain in the *** I have ever had to remove...even after blasting and tons of penetrating products. Only got one out and I am going to have to dremel off one screw head on the other side to split the caliper. Anyone else have this much trouble?

MAGK944

Yes those 4 allen bolts holding the stainless steel guide plates are known to be a pain to remove. They are angled in a way that doesn't allow much leverage on any tool to get them out. Percervere, definitely worth it to get the calipers painted correctly and those guide plates clean up really well once removed. You will need new allen bolts (McMaster) in most cases, I had to use lock-jaw plyers to get them out and that chewed them up really badly.

Have you tried a heat gun and then sticking a cube of ice on the bolt head before attempting to remove it? Apply the heat and ice method after OCD cleaning the calipers and spraying penetration oil to the bolt then tapping on it for hours. Sometimes it works.
