The bore on the M/C is to small.. Need to go with a 1.00 bore M/C.. If the bores on calipers are 1.75 & 1.375 in rear, this the m/c bore size I would recommend.. another thing you want to look @ is the clevis mounting hole on the pedal.. OE levers have to points to mount clevis on pedal.. The highest hole on pedal is for manual brakes to attain more leverage out of the pedal.. the lowest clevis hole is for power brakes, the booster will aid in leverage from the pedal

The stopping power is just not there. I tried a few simulated panic stops from 50 mph and could not even achieve lockup. So maybe the next step is to add the power assist of a 7" or 8" dual diaphragm booster to the system for some more pressure.
My engine is a ZZ4 350 with the H.O.T. cam, so vacuum is not a problem. I also have a Wilwood proportioning valve that can be added as well. I'm just not feeling the love with a Hydroboost system, I have a couple friends that have them and love them but it just seems like the majority of folks pass up this choice. The majority of my driving is just cruising, but I plan on attending the Motor State Challenge next June, so occasional track time too.
Any recommendations??
