Okay guys needs some brake help

[king-918]

My 86 SWB has never had brakes since I owned it now I need a good aftermarket adjustable proportioning valve and hopefully a link on brake lines, thanks in advance

Inline Tube for the lines, buy the stainless, NAPA for hoses, Raybestos or AC from FLPA or Rock Auto for calipers etc. Why do you need an adjustable valve? Did you go disc on the rear? Otherwise look at a stock set up.

4wheel disc conversions don't need an adjustable combination valve. Several options exist for drop-in fixed combination valves that are properly balanced for disc/disc systems.
Here's one of them from Right Stuff.

I assume you are installing a Master Cylinder/Power Assist biased for Disc/Disc systems... If you aren't changing at least the Master Cylinder to a Disc/Disc unit stick with the Disc/Drum combination valve.

Thanks for the reply. I do still have the stock booster and master but they can be replaced too. the truck and been converted to rear disk and the bed will constantly hold Atleast 300 lbs of extra weight.

Do you know what the lines are called by any chance or part#

If you don't want to convert the MC & Booster keep the factory combination valve & install an adjustable bias valve in the rear brake line.

Wilwood, Tilton, Baer, etc make an inline rotary "Proportioning" valve to adjust the rear brake bias. I'd stay away from the adjustable combination valves.

I will say this... Some of the bias is controlled by the piston sizes in the MC and rear calipers.
I've converted two 1970's German Water Cooled A1 VW's to 4wheel disc brakes using late 1990's A3 VW rear disc components. I didn't change anything but the rear brake and stub axles. They didn't lock the rear wheels even in simulated panic stops. They did cut my braking distance down significantly.

You may want to assemble the system, bleed it, and test drive very late at night in a large empty mall type parking lot or long dead-end commercial street. Bring a couple friends to help, take some tape measurements, put out some cheap cones, and write a bunch of stuff down. If your local LEO are not complete asshats and you are obviously serious they won't bother you.

If your truck's tires are the same size front & rear, and you are using stock calipers and discs, with drums on the rear, then go ahead and use the factory type proportioning valve.

If your rear tires are taller than the fronts, or if you have larger rotors, then use an adjustable valve for optimal balance.
