Paportioning valve

What would you recommend for rear disks.

Using 3/4 brake setup.already have one ton master cylinder from a K30 mounted to stock V6 brake booster, rear D70 using K20 rotors and 3/4 ton front calipers.

Just buy an adjustable one. That way you can get the brakes the way you want them. Either more or less rear brakeing.

That's what I would do too... Some say you can just leave out the prop valve on a rear disk setup, but I think an adjustable one would be great to have to fine-tune things.

Yep, adjustable. Stock ones don't do anything useful for a wheeler, and they just make for a brake line routing nightmare.

They're only like $40 from Summit - why waste your time with a non-adjustable one??

They only sell 2 I think and the house brand is 1/2 the price of the name brand. I bought one local to me from a sandrail shop. If you can buy it local go for it always nice to support your local guy

Summit sells more than 2. They sell alot. also im looking for the brakelines that come off the calipers, where would i find those.

I bought the $40 wilwood knob model. It's probably exactly the same as the $35 summit one, but for a few bucks I'll stick with a name brand.

I have no idea which calipers you're talking about...

Paulie · May 22, 2006

Wilwood was my choice as well. im looking for the rubber brakeline that runs off the caliper to a hardline which routes up to your main brakeline. Heres a pic of what im talking about. where would i find there brakelines.

I think those are generally application-dependant. You could probably just go to NAPA and look through their books to find one that works if you know what you need, like Banjo fitting or flared? How long? fitting size at the axle end?

I just got done putting rear disks on and used Monte Carlo calipers, so I just ordered the lines and banjo bolts to go with them. I had to cut and reflare the hardlines with the right nuts to get everything to match up, but no problems.

Bobbo3234 · May 22, 2006

yeah i got mine from NAPA. You might have options for lengths too

Toyoda1 · May 22, 2006

do what me and my local buds did. go to your local hydraulic supply shop with the rubber brake line and they can custom make you the lines while you wait. Its about the same price as the ones you buy at a store but this way you can get custom lengths. I prefer this way over a store bought. We even compared the custom ones to some goodridge lines and i think the custom ones were higher quality. Just an idea.
