63 Nova Disc front all new Drum rear all new Dual Master cylinder, looks fresh but I'm not 100% positive if its for a Drum/Drum or Disc/Disc All new brake lines, but currently have no residual check valves in the system. All of the lines were new and pre-bent when I purchased the car, from reading residual valves are recommended by some and not by others. Currently have the Basic summit proportioning valve Stops decent but would like to maximize all the new stuff to the full potential ! Chevy2 has this version http://www.parts123.com/parts123/yb.dll?parta~dyndetail~Z5Z5Z50000132a~Z5Z5Z53383~P149.95~~~~S3K704G3FI99121816214a~Z5Z5Z5~Z5Z5Z50000132A# ^ Would this setup improve braking ^ Any other questions you need to know just ask... Thank You !
When I added the front discs on my 55' Stude I talked to SSBC. they were very helpful, which master cylinder bore, prop valve, etc. I set my car up how they suggested and it stops like it has power brakes. It has a front disc/drum rear, a 1" bore mc (69 non power chev truck disc/drum) and one of the prop valves that both lines off the mc plumb into.
A picture or description of your master would help determine if it's correct. All drum brakes made before the mid '70s should use a residual valve, but later production drum brakes can also benefit from a residual. The company shown above, like many, sell brake components they know little about. That "prop valve wire", for instance, is for the pressure differential switch, which is part of the combo valve that includes the proportioning and hold-off or metering valve. Short answer, you do not need or want that combo valve on a vehicle it was not designed for, period. All you need is the adjustable prop you have and an additional residual to the rears.
converting a '63 nova to disc/drum: '69-74 Nova's had disc/drum available. Use a master cylinder and metering block as found on a '69-74 Nova. Done. No need for the extra ****.
if you're trying to figure out if it's a drum/drum or disk/drum disk/disk mc, look at the size of the reservoirs. Drums use small reservoirs, disks have large ones. The reason is that disk brake calipers "take up" fluid as the pad wear, so they need extra fluid capacity.
I've never found a need for streetrod brake parts like this. I've used several kits to adapt calipers to different spindles but I've never needed any streetrod parts to make them work properly. No aftermarket proportional valve or adjustable distribution valves. I prefer to use factory GM parts. I did my first 34 P/U prior to all the aftermarket hype using everything from a donor 71 Camaro. Only the location and brake lines were changed. I did get a new M/cyl and rebuilt my calipers and w/cyls so everything was new. I think it's still running the streets.
My Cast # 5468309 Google : 67-69 Nova/Camaro's and so on, looks to be Disc/Drum I think I'm just find
