Piston diameters of 944T/951 caliupers are 2 x 40 mm + 2 x 36 mm. The piston area of one caliper is 4550 mm2. The piston diameter of the original SC caliper is 48 mm and the piston area of one caliper is 3620 mm2. That means, that when you press your SC caliper pistons out 1 mm, the pistons come out from 944T/951 caliper only 0.8 mm.
But, if we study the caliper piston area / master cylinder piston area, we will see that SC caliper piston area / 19 MC => 2 x 3620 mm2 / 280 mm2 = about 25,5 944T/951 piston area / 23 MC => 2 x 4550 mm2 / 380 mm2 = about 26,7 So, the pedal will be firmer with 23mm MC than it used to be with 19 MC and original calipers. If you want the same ratio, you should use 22 mm MC. I am here only speculating, not saying anything. |
