944 Turbo Caliper Problems

[T151]

Mike,

Do you have any of these spacers?

[Michael Ghia]

Sorry mate, no. I think they're only 2mm thick or very close to that.
You could just use some M10 washer to make up the thickness until it clears. They're not going to go anywhere. Up to you if you want to buy the proper Porsche items.

The spacers are just washers and you need to get the caliper centered on the disc.

There are no Porsche part numbers on the calipers but, what I believe, is a Brembo part numbers that I know nothing about.

One thing to consider, that I've seen in the past, is that the front and rear calipers can get mixed up. Their mounts are slightly different and if you bolt them up it will catch the disc as you described.

I thought that I might've havd the front and rear calipers mixed up at first, but looking at the caliper the 'front' calipers have a wider provision for the disc (rotor). When I tried them on the back the same thing happned!

I'll get some spacers then!

Is 2mm the confirmed thickness?

i believe so, but just get whatever centers them on the rotor. btw, the fronts have much bigger pistons than the rear. that is the easiest way to tell the difference.
