I picked up some 944 turbo calipers at the swap meet at the Ventura show, I was told that with slight adjustment of the mounting holes they will fit on my 911 front end. They are aluminum black and say "PORSCHE" in raised lettering and it says BREMBO on the back , they are 4 pistons the top pistons are slightly smaller than the bottom ones . They said it was origionaly from a 89 944 Turbo. Have any of you guys seen this done ? Would it work with my 15inch rims ?

Yes they will fit on 15" rims, And they will fit the 3.5" struts if they are machined slightly inward. Big reds need 16" rims.

Are these front 944 calipers? What are the piston sizes?
I picked up a set of rears (I think) that have 28mm pistons in all bores.

Looking at the calipers Aaron had, they mounted differently. As I remember the bolts ran 90 degrees to the 911(914) frontend. Could be wrong, happened before.

I have a set (both front and rear) on my 914.

It was not easy to do on the rear. I had to cut off the mounting tabs for the calipers and weld on new ones with the proper bolt pattern for the 944 calipers.

I would not do it again.

Boxster brakes are a bolt on and they work even better.

Can anyone be more specific as to the pistons used in each of the available calipers. Are all the pads the same size? If not, how many varieties of pad sizes are there?

As said, front '86 944 turbo caliper has piston sets with different size, one set is quite a bit larger than the other. Rear caliper has 2 same-size piston sets. Don't know the exact size of the pistons though.
For pads you could consult the following catalog. It will show which calipers use the same pad. Second half of this catalog also shows the different disc sizes (diameter and thickness).

The pad size is the same for 944 front and rears. Forgot the piston sizes as I sold my fronts.

Thanks to all of you !!! When I order Pads would it be for an 89 944 Turbo ? Would that be the correct year ? Also I don't want to sound to dumb but does the Maltese shaped brake pad retaining wire just pop out with pliers or do you have to unscrew it's latch ? It does not want to come out easily and I don't want to break or bend it.

Clay, I am just doing the front brakes would that be very difficult ?

Depends on what struts you have up front. Later struts with the 3.5" spacing will be OK. You'll need to get to a 3.75" spacing. I believe most have the ears on the calipers machined to the 3.5" spacing.

You should be able to pinch the retainer and thus unlock it.

If you go on the Pelican 911 Technical list and do a search you will find lots of excellent info. Follow the advice of Bill Verberg and Grady Clay. I think the best advice is to mill off the existing caliper mounts and bolt on a set of adapters. However, I don't see why welding up (plugging) the existing holes and drilling new ones will not work well. Perhaps welding causes more problems than milling and drilling.

The holes have to be drilled slightly offset, both closer together and inward. I don't know the exact measurements. I had Wes Hildreth do it. He has done a bunch of them.

I've got a set, but good luck finding rebuild kits. You can't get them through Brembo last time I contacted them, and Porsche wanted $170/kit.. for Orings and Pistons????
