Hey I have some question mostly about rear calipers on my 87 shelby z. Three years ago I changed disk and pads, on the inner side of the rear calipers there's a hole with a screw for adjustements (first time i saw that Oo). I tried to be logical about that; i used the screw the same way we torque wheel bearings. I tightened it till the disk gets locked, loosened it and tightened again by hand. Some days later the rear left wheel got stuck and heated and untill then, i have no handbrakes on the left (the cable probably broke). I neglected it but now i want to repair everything that has to be done. I may have done it wrong and never found any good information about that (haynes manuals and mitchell shopkey doesn't know there was rear calipers it seems). Any of you guys have good hints about that? Thanks!
PS: Sorry for my english im french
