Hi guys i just helped my buddy convert over his 62 Chevy Bubbletop over to 4 wheel disc brakes. the car originally had 4 wheel drums and stopped fairy good. We installed a Wilwood Dynalite kit with a 15/16 tandem manual master cylinder. We installed a new Classic tube stainless hardline kit for the dual circuit as well. Wilwood combination prop valve as well was installed. the car stops OK, not as impressive as we expected and not as aggressive as the drums we removed. We pressure bled the system 3 times using the Motive Power bleeder and my Phoenix bleeder, def no air. the pedal seems to have a bit more travel before it engages as compared to the 4 wheel drums we removed. pedal also feels a tad spongy but it might be from the master cylinder bore and caliper pistons When we went out back and opened the lines after a few test drives fluid does pour out evenly, when we go up front and pull one of the front wheels and remove the braided brake hose at the caliper fluid does not pour out at the same rate, almost get 1 drip and thats it, seems like something is weird. this had us thinking last night if maybe we should install 2lb residual valves on the front circuit or not? I have never used a residual valve on any car and was always under the impression this was for guys with drum brakes or masters mounted under the floor on hot rods. any suggestions here guys? Why would this lack or pressure occur only on the front circuit with a firewall mounted master? would we need 2 residual valves up front?
