i'm looking at my master cylinder.. instead of having a Front and Rear i have a P and an S going to my ABS box.

the P is closest to the big brake booster (chamber 1) and the S is at the very end of the master cylinder (chamber 2)

does anybody know which is front and which is rear? p/s?

 

bump for a good question..

 

There is no front and rear, it's side to side with a criss-crosses from front and rear.

For example, right front and left rear or left front and right rear.
