Mounted on Jeep CJ-7 with 4 Speed Hill Climbing Handle. Only sticks to the front brakes but holds very well in almost vertical situations at 4 depths. I don't feel the need to install it on the rear brakes as previously planned. I chose the bundled install kit, sold separately, as I live 20 miles from the nearest parts store. If you're working alone you can also order some bleed valves (another great product - look for that), although it's not necessary.
