Master cylinders for larger brakes
 
Does anybody have any experience with alternatives to the stock 3rd gen master cylinder when using upgraded front calipers with stock rear calipers? I have Wilwood Superlites on the front of my car, and the pedal is way to soft and has too much travel. Its nearly impossible to modulate. I definitely need a M.C. with a larger bore, and the only "bolt on" option I've heard of is the 929 M.C. Are there any others that will work with the stock booster? Any opinions on the pedal feel with the 929 master cylinder?

Check this out: http://www.crookedwillow.com/mastercyl.htm

Duane says that he's putting together another run for production in 4-6 weeks, and the price might be a little better (sit down anyways, though)

Seperates the front and rear with their own master cylinders.
Looks pretty trick, and eliminates the power assist and supposedly still provides a rock hard pedal feel. If he can keep it low $1000+, I'm interested. Anything to help clean up the clutter under the hood...:D

That master cylinder setup is a total ripoff. You can buy a pair of Wilwood master cylinders, a balance bar, and a proportioning valve for around $300. Make a little metal bracket to mount it up, and have the same thing as what you're buying from crooked willow. I really don't know how they can possibly justify that price. It would be interesting to hear from someone there as to what's so special about it.

There's no justification that I can find for the cost. Even with a reasonable mark-up, the kit should still only cost $600-650. I was charged $1,600 but Mark talked me out of it, and I heard that some people paid even more.

I would like a similar setup to eliminate the power brake booster, since I won't be making enough vacuum without an electric vacuum pump to make the brakes function properly on my car, but I'd much rather get a 929 master cylinder and the pump for an additional $300, than pay $1,500 or more for a manual setup.

Just go here and learn everything you need to know to do the same setup yourself for 1/4 the price - http://www.wilwood.com/products/techtiplocator.html

I think a master cylinder off of a same year 929 can work.
