318iS Brake Master Cylinder

[dude8383]

Hey peeps!

I'm tired of dealing with my braking issues...
(read here)

I decided to switch back to the stock master cylinder setup however the part number for the 318iS is 34 31 1 161 866 vs the 325i's 34 31 1 157 206.

Both are 22/17 as far as I'm concerned. What the heck is the difference between the two? They're both for ABS systems but the former is nearly $300 whereas the 206 is about $200.

Anyone run into this issue when purchasing a new master?

Interesting, I had no idea they were different or what the difference would be.

Wanted to let you guys know that the 325i master works 100%.

Installed it just a few days ago

As far as I've ever been concerned there isnt much of a difference, glad to know it worked!
