Title: Brakes
Post by: BillyWillicker on April 13, 2011, 11:11:23 pm

Hi!  I have a 1990 Audi 90 quattro that I am putting a 1.6TD into and am also uprating the brakes on.

I have wilwood superlite II calipers in the front and wilwood dynalite billets in the rear and will be running a dual master/bias setup.  There is no power assist and I am wondering what size master cylinders to run for the front and rear.

I can use 1", 7/8", 3/4".  I have to measure the piston diameters on the calipers yet, I know that is a big thing to know but I am looking for suggestions.  Thanks guys.

Might want to contact Wilwood tech support and see what they recommend:

I have some Wilwood 4 piston calipers on the front of my 4x4 (plus some single piston Celica calipers on the rear) and will be upgrading to the 1" bore m/c.  Currently running a smaller m/c and I do bottom out the pedal to just barely get the tires to lock up.  With the large m/c, will also be installing a dual diaphram booster to cut down the increased pedal pressure.
