Works the way it should. Love line locks

Input and output are in line making it easy to install

Work just as expected

I have never used a solenoid so reliable. Works great. The way I use is. Come to the water box hold the button. Pump the breaks. Do the burnout and let off the button.

Put these on a first generation 4runner as a parking brake while using the winch. That way all four tires are locked with the engine running to keep batteries charged. Turn on my lockers and it's a 3500 pound anchor nothing turns. It's also nice that I can turn it on before I stop, and once I hit the brakes to stop I'm parked, pressure goes through and holds. I installed using Swagelock fittings, just cut the brake line, and install the swagelocks. Then loosen the swagelock install the line lock and tighten the swagelocks back up. I was skeptical about the swagelocks at first but after using them once I love them. LCE has them in 3/16 for a reasonable price.

I just recently installed and tested on Jack stands, holds front brakes like it should. Will have to see how it performs in the burn out box but as of now I am happy with this product. No leaks, unlike the Hurst solenoid that is twice the price and leaked from the bottom plug right out of the box.

Works fine but I was misled by some other reviews that it can lock out pressure being sent to brakes. Untrue. I put it on my rear brakes thinking I could activate it at zero pressure no brakes and then that would make the pedal control only the fronts but that is wrong. It acts like a check valve. On at zero and then braked will let pressure though but then will hold that pressure on the brake side when pedal released.

Seal inside swelled before I was even able to use it for intended purpose locking front brakes. Had to crack bleeder screw on caliper to release pressure to get vehicle home
