1973 C10 Rear Disk Brake Conversion Proportioning Valve
« on: February 14, 2018, 09:04:49 PM »
I fitted my 73 C10 with after market rear disks and an adjustable proportioning valve?  I gutted the existing proportioning valve and will continue to use it for a brake line distribution manifold.  The driver side end needs to be plugged after the valve is gutted.  This can be accomplished with an 18.5mm drill bit and a 20mm tap and plug, easily available on the internet.

I understand what you are talking about. I am thinking of doing the same thing. I plan on installing hydro boost with an adjustable proportion valve at the master cylinder. Can you go into more detail on how you gutted the proportioning valve and made it a manifold?
