Wrong master. You need a 7/8" master, not 1". Makes all the difference in the world. The part number you need is a 260-9439, add a (P) if you want polished.

I called the Wilwood tech and realized a major issue on my brake lines to the front brakes, i made the dumb mistake of using the 2 front ports to plumb the lines when i should of ran one to a tee, I will make this change this weekend and try again.

We do 100s of Wilwood systems. It will still be the wrong master Rick. Go ahead and change it while you fixing the plumbing.

Frank,
Thanks for the suggestion I will do just that, I have a call into Michael Hamrick at Wilwood to try and swap it out.

I wish you guys were on the west coast!

Yes, the 7/8" bore Wilwood MC will make a considerable difference in place of the 1" bore unit. If you find that you are still not happy, Frank is also a Hydratech dealer and can set you up with one of our systems.

If I run the hydraboost can i keep the 1" master?

Yes, you can retain the 260-8555 1" bore Wilwood MC. We typically spec a 260-8556 1 1/8" version for a slightly firmer pedal, though your existing 1" version will run appropriately. Frank can set you up with either system # 3021 or # 3023. The new design Wilwood MC is a GM early / deep MC pushrod interface as you pull it out of its box, and this can plug n play with our # 3023 assist unit with the long MC rod. Or? Alternately, these new design Wilwood MC's come with an aluminum spacer plug or bullet that inserts into the deep MC pushrod hole for use on the 2nd Gen Camaro / later short MC rod spec - will interace with our # 3021 model when run with the spacer bullet.

Alright. Here come some dumb questions: I am having the exact same problem. Have not even looked into yet as I've had other fixes I've been working on.
I have wilwood MC with Baer brakes. Whats the easiest way to know what bore I have on MC? I will go start to investigate as that is the project I am tackling starting tomorrow.

EDIT: Ok, couldn't wait til tomorrow. So I just looked. I assume the "1" on bottom-side signifies mines a 1" bore?

So RSK68, what solution did you ever come up with? I think I have exact same problem!

Add power or better yet Hydratechs hydroboost system. I've never had manual brakes that worked well enough to make me happy.
