Cofirm 993 C2 master cylinder size
 

Can someone confirm, or set me straight, on the 993 C2 master cylinder size? I show 23.81mm?

TIA.

Hey Bill,

According to the excellent brake system information that Bill Verburg has made available (search on his name, click the link in his signature, and then find the brake page), the master cylinder size is in fact 23.81 mm for a 94 - 95 C2 and C2S. I wouldn't have thought the MC would have changed, but if you are working with a later MY then you may want to verify with another source.

Regards and happy holidays!

Bill, Doing the upgrade today? I'm out in the garage doing the oil fan balast resistor on the 993(grrr) and had to come in to get the directions. Let me know if I can check something or help based on my upgrade. I don't have the PET at home but do have both 964 and 993 manuals.

After the 993 resistor I get to install my new transponder in the 964 and look at how I'm going to do the cool suit install. :)

Bill greetings from Fla. I don't have the spec books here but to the best of my knowledge the specs on my brake page are correct.

964 vac 20.64mm
993 vac 23.81mm
964 hyd 23.81mm
993 hyd 25.41mm
964 RS hyd 25.4mm
