Title: Front brake master cylinders
Post by: kenray on June 06, 2015, 10:36:58 AM

What is the difference between a k75/100 non abs front brake cylinder vs an abs front brake master cylinder.  Thanks for any info. Ken in Katry Tx.

I think the piston in the ABS version is a little bigger.

The ABS master have a adjustement screw at the lever, and a harder material at the lever end of the piston.

I think I'm wrong. I just checked the fiche and it appears all the rear pistons are 12mm and all the front pistons are 13mm.

Rear master did change from 13mm to 12mm during -88.
