944 Turbo Caliper Problems

[T151]

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.

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

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.
