Well i'm still working out the bugs and brakes are one of them, I have Willwood 6 piston fronts and 4 piston rears with a Wilwood 1" master cylinder, the pedal is rather hard and feels like it just isnt stopping the car, like theres just not enough pressure, i vacumm bled the brakes and cant remember if i bled the MC, any suggestions on what i should try or look for, i also have there praportioning valve but its screwed all the way in for an open circuit. I guess the first thing i should do is bleed the master due to i cant remember if i ever have.

Hey Jody,
yes brakes are manual, and ignorance steps in, what do you mean bed them? are you talking about a stop and go type procedure to brake them in, if so no i havnt done anything other then try to stop and its a little scary.

yes thats bedding them in... and if you dont recall bench bleeding the master then just do it to be safe... maybe check with wilwood on the proper bedding procedures ie:speeds/wait times for the pads you have i would bed them first before you attempt to bench bleed the MC cause either way the pads need to be beded and if thats the problem it saves you from haveing to pull the mc. have fun!

if you hadn't bled the mc, the pedal would be soft and spongy or just go right to the floor. It wouldn't be hard. It sounds like either your pedal ratio is off or the master cylinder has too large of a bore size for the calipers you are using.

What is the bore for your master? 1" for manual brakes and 1.125 for power brakes. Sounds like your bore is too big. Bedding the pads has nothing to do with the feel of the pedal. It helps the pads contact the rotor, but has nothing to do with the hydraulics.
