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:)
