Question about master cylinders and brake boosters
 

Is there a difference between NA and Turbo S5 master cyls and brake boosters? Im having a fluid leak issue and am looking to get used ones until I have money for new units. I just need to know what to look for. Thanks.

the only difference is between base models with single piston front brakes, and ABS models and everything else.

So there are three types of master cyls (+ differences in series).
