brake calipers

[The '91 beast]

This is a simple on guys. In in an auto shop at my school and we got this 91 ranger in there that has been rubin metal on metal fur 3 days. He has grinded some major groves into his rotors. All i need to kno is how to get the calipers off. Ive never seen caliper bolts like that before i dont even think they r bolts. but anyway if anyone can just tell me reall quick how to get em off that would be great. Thanks.

They are slides/pins. Rubber sandwiched between two pieces of steel. They make a special tool for the job, but a flat point punch works good.

There are two of these pins on each caliper. The book tells you to replace these pins when repairing the brakes,but I have reused many of them.They cost about $6 each.

Drive them out by driving them toward the center of the truck. Likewise, reinstall them by driving them in from the outside towards the center of the truck.

There is a right way and wrong way to put them in. Notice that there is a taper (slight V) shape to them. If you look closely, you'll see the difference.
