Very hard brake pedal marginal stopping

[Dennis Mosley]

Hi guys,

I purchased a 13 year old cobra that had some pedal issues. I replaced the brake pedal with a Tilton unit, replaced the master cylinders with new .75 Wilwood units that have remote reservoirs. The front calipers are 4 piston Wilwood Superlites and the rear are Jag.

The problem is that once hooked up filled and bled, the pedal is super hard. Doesn't feel like it moves more than 1/2 an inch. Also if I'm gong greater than 10 miles an hr, I can't lock of the brakes.

There is no power booster so that can't be bad.

I've adjusted the push rod out to pretty much the very end. I've adjusted the balance bar so that it is bias to the front brakes to try to get better stopping.

Before the lines were attached, the pedal had free travel so I know there is nothing in the way of the pedal moving.

Any tips on what I should check and why the brake pedal is so hard?

Thanks
