Can I use the Truck Iron to block the brake pedal, if I want to do an applied brake measure?
Yes you can, by just placing the hammer head against the front of the drivers seat and the claws against the brake pedal. Then useing the fore/aft adjustment on the seat you can block the brake pedal to whatever position you want. If you have an application air gauge you can pretty well set whatever pressure you want to test at, just by moving the seat forward or back.
