I just installed a stock spindle upgrade to front disks. It came with the master, prop valve, calipers and the brackets were from another company.

They look great. But, the pedal goes to the floor. They seem to work...but how good?

I have bench bled the master twice. bled the entire system at least 6 times.

If i block the master off, the pedal is hard. With just the prop valve and the front line connected is it still soft. Should it not be hard? Can air be in the prop valve or it be defective?

Can I just run the lines off the master and try it? Maybe put an adjustable valve on the rear if this fixes the pedal.

What size connectors are on the master?

'51 Chevy Car
Manual brakes
Dual master / prop valve on the firewall
Disk front / drum rear
Hanging pedal from walton fabrication

Thanks for any help.
