944 Turbo Caliper Problems

Got brembos on my '03,

But when I bolt up the rear calipers, they lock against the disc therefore the wheel cannot turn.

Using late aluminium arms with late 4 pot calipers.


Anyone got any ideas?

There are some type of washer/spacer that should go between the caliper and the mounting area on the arms so the calipers are pushed inward(toward the transmision) so the rotor get centered on the caliper.

Need more info here; what discs, hubs, pads, etc. Give all the details, including the year of the Porsche parts.

Spacers for rear calipers

As far as I have seen (please correct me if I'm wrong), all 4-pot calipers fitted to the rear of any 944 or 968 came with spacers between the caliper and the caliper mount to centralise the caliper over the disc.
Here is the part number 999.025.131.02

More details,

Calipers - I think they are 1990 calipers, from a 944 Turbo with ABS. The caliper itself has a pad wear sensor built in. Where is the part number?

Discs - to match the calipers, late 944 turbo discs (I think they are 11.8")

Trailing arms - Late (post 87) aluminium with ABS sensors built in.

Hubs - late (late aluminium arm style) hubs,

Pads - ?? Match calipers

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.
