Hi everyone,

My FC's Brake Master Cylinder is failing, and I can't seem to find the exact replacement for the one that came with my car...

Mine is a NA FC, 4pot Front Brakes, ABS, AAS, and vented discs.

Here you have a couple of pics of the unit itself









I already got two different new ones, but they don't match this one... got one from a S4 T2, and one from a S5 NA... no luck

Can any of you guys help me identify the one pictured?


Thanks in advance!

Try RockAuto.com; looks like they may have 4 to chose from: Wagner, A-1 Cardone, Cardone, and Raybestos.

Good luck.

It does look like a S5 Turbo one... right?

Your car has an interesting array of features, being N/A but still having ABS. It sure does look like an S5 Turbo master cylinder to me. The outlets are in the correct location, and there are only two of them.

Interesting? Don't even get me started...

S5 NA body
S5 Turbo brakes w/ABS
AAS
S4 6-PI Engine
Butterfly-valve style Aux Ports, actuated by a solenoid
S3 Electronic Distributor
Thermal Reactor

and the list goes ooon...

I thought ABS master cylinders had an opening on the bottom for the ABS pressure switch. I've never seen an FC with that shaped reservoir before...?

I thought all FC master cylinders were cast iron, that looks like aluminum.

What does the booster it came off of look like? You have a pic of that too?
Is there a stamp on the bottom of the cylinder like 15/16?

A pic of the brake booster would deffinity help, I'm thinking the PO might have done a booster / mc swap.
