I must have got lucky, mine will hold my truck and trailer on a slight incline. How does this system work, does it push on one side of the brake pads on the axles or does it have an additional rotor someplace (like big military trucks)?
Thanks for telling me where to adjust it. If the time comes I can do it myself.
your not suppose to adjust the cables. there is an adjustment star that you turn on the inside parking brake shoe (just like on a car with rear drums). you have to remove the rear tires and you will see a rubber plug on the rotor. remove it and with a flashlight look in the hole and turn the rotor until you see the adjustment star. its either on top or bottom. with a screw driver crank it up or down until it stops and the rotors is locked. back of about 2 cranks and make sure the rotors turn and your done. the cable adjustment is only if the cable gets stretch after using it alot.
