I like to hear everybody's experience with which m/c to use with the various tyoe of breaks.

I have had a 1303 with which I used original front discs and 944 discs (old slider type, appr. 1983/84) at the rear with original VW m/c. This works great! IMO because the rear 944 piston caliper is larger than the original rear drum cylinder of the 1303 and thus giving more brake pressure. Since the weight of the bug engine is behind the rear axle, it braked even better without locking up the rear first.

I now have 944 turbo Cup brakes front and rear and still use the bug m/c. This works not well at all. Front locks up very quickly and the rear hardly gives any brake result.

IMO everything has to do with the combination of the caliper piston sizes, brake pad sizes in relation to the piston diameters (front/rear) of the master cylinder used.

Could anybody inform me about the piston diameters of the brake master cylinders of the bug/1303 and 944 (turbo)/911 ?

I think from a weigth distibution point of view, the 911 m/c should be closest to a bug with discs front and rear. And it has no servo (pre 3,0 ltr?)to find room for. Can you bold it right on?

I' am interested in the opinions from you all on this.
