Wilwood is always good
I needed a proportioning valve and the stock one for my truck is not made anymore and this one works great with the added benefit of being adjustable

This works
Had to replace my old one that came with my disc brake set up around 7 yrs ago. Started to leak out the stem. This bolts in the same, lines fit the same and works the same with no leaks. Also carrys a well known brand name. 65 mustang stops again.

Doesn't fit Toyota applications
This seems like a great proportional brake valve, but beware if you are trying to install on a Toyota (and possible also Suzuki) application. Toyotas have metric M10x1.0 brake line fittings that do not mate with either port option provided with this valve. The threads in the stock brake lines are deep and even if you purchase a 1/8-27 NPT male to M10x1.0 adaptor with inverted flare (which is nearly impossible to find), it STILL will not work because the vehicle brake line fitting threads are too deep and the adaptor fitting is too shallow. Wilwood does sell a separate metric proportional brake valve for metric applications, but it's unclear whether its female ports include an inverted flare. Proceed with caution:)

Worked For Me
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.
