I plumbed this proportioning valve in between the master cylinder and the rear brake line. Great little safety upgrade because the factory distribution block has no metering or pressure limitation so every time you step or the brakes you’re sending full pressure to all 4 brakes. I have power discs on all 4 wheels and without this valve my rear discs would lock up first. Not good.. so now I can adjust the amount of braking power that goes to the rear!

I replaced the bed load actuated proportioning valve on my 27 year old Toyota pick-up. Front brakes were locking up and I skidded dangerously, especially on wet roads. This was a tough install with a custom modification to the bracket and custom line attachments. I bought a line that matched this then cut the metric ones off my brake lines and flared the new fittings onto the existing lines. Had to plug the return line at the front brakes “T” but everything fit and worked well. Adjustment takes time with trial and readjustment, but if you mount this unit where it is reasonably accessible, it is easy. For heavy loads, I can either drive more carefully or readjust. I brake much more safely now. Good product.

Good quality. I installed and I am currently adjusting my system. I had to cut and flare my current brake lines to fit into the valve.The build quality looks great

works very well…just what I needed to adjust the stopping pressure from front to back.
