    I may have what you need, but Wilwood needs to tell you whet bore size is required.

    Money you enjoy wasting is NOT wasted money... unless your wife finds out.

    Re: 4 wheel power disc brake master cyl recomendation

    Had a reply back from wilwood tech staff


    Thank you for the inquiry and use of Wilwood Disc Brakes. Are you running manual or power brakes? For power brakes, how much vacuum are you running to the booster at idle?
     
    For manual brakes (no booster), a 6:1 pedal ratio is the minimum we recommend.  Please confirm your pedal ratio.
     
    http://www.wilwood.com/TechTip/TechPedalTip.aspx
     
    You have two options for master cylinders that may work for you. If you like good pedal modulation and the car is mostly street, the 7/8" bore Aluminum tandem master cylinder will be a good choice.  This will provide you with about 1000 psi of pressure at the calipers with 100 pounds of leg effort. The pedal will travel about 1/3 before it firms up.

    A 1 inch bore is also usable.  This will stiffen up the pedal, making about 800 psi under the same leg effort. This option is popular with drag race customers.

    I really try to not use this forum as a sales tool, but if you want a good mc meeting those specs for $75 just email me.

    Bob, no offense taken.  Here is the way I figure it... The users of this forum voluntarily donate their hard-earned dollars to support this forum and keep it pop-up-ad free.  I just don't think I need to try and make money from the forum and expect somebody else to pay for the advertising.  My purpose for having this forum is to HELP others who need it, not to push my products.  But, every once in a while, if someone is asking about a specific part, I will tell them what I have, but politely ask to be contacted off the forum.

    That's just the way I look at it.  I tolerate others getting a plug for their stuff once in a while, but I draw the line at anyone who is in direct competition with my products.  I would welcome input from others on this subject if you guys want to express your opinions.

    This is MS's web site, he makes the rules, plain and simple!
    Donations are solicited to keep this place add free, which I am sure everyone appreciates.
    His offer to help in most instances is done for the benefit of the poster  by relying on Steves extensive research on what works and what does not.
    Happy Holidays all!
