Brake balance

[Patrick]

Vince's car at Willow Springs on Friday 12/2/2011.

It has a 7/8" master cylinder for the front brakes, 3/4" cylinder for the rear. No proportioning valve. When we set the balance bar all the way in the direction favoring front brake brake bias, the car still locks up the rear brakes when testing at low speed (10-15 MPH) in the paddock area. I'm concerned that changing the rear cylinder to a smaller, or front cylinder to a larger may result in the balance bar contacting the outer tubular housing of the balancer assembly. It is possible that the cure for the compromise is to install an adjustable proportioning valve in the line going to the rear.

I found this Tech Tip cheat sheet online from Wilwood. It offers a few band aids to adjust around concerns, but it doesn't really address the problem.

Here are a few graphics of the assembly.

An old acquaintance, Steve Ruiz wrote this up and it's worth the read for those who need help and direction.

I would contact Todd over at TCE in Tempe, AZ. He's good, but so is Jack Hadley at M&M.
