Hello, While rebuilding my rear brake calipers i accidently broke the one parking brake pad. So, i have to replace all the pads. I picked up a set of beck/arnley pads and changed the two on the outside. Then i ran into a problem, how do you loosen the nuts on the back side so you can change the pad out. Because the handle is so close i can't get a wrench, or any type of socket in on it. - Shain #10140
