Perhaps I'm just not getting it, but I looked on the FAQ section of the home page here and I dont understand how to go about fixing the actuator screw problem on my rear claipers. The e-brake is virtually non-functional and Pat from "Gosse's Garage" on WJFK says that the only way is to replace the calipers. Well, they want 75.00 for the core charge, and 70.00 for the calipers themselves. Any suggestions??
