How do you disengage the caliper when changing the brakes and rotors on a 94 Ford Explorer?
First remove the cover from the master cylinder resevoir. Then place a chisel or punch on the corner of the outside end of one pin and strike it with a hammer, moving the notch of the pin inside the groove of the caliper and knuckle. Repeat this on the opposite corner of the same pin (still on the outside), and then you should be able to slide the pin all the way out the other side. Repeat this procedure on the other pin and then you should be able to remove the caliper. Compress it with big channel lock pliers or a c clamp so that it will fit over the new pads and rotors. You may see fluid coming from the master cylinder while compressing the pistons. This is OK but try to clean it up so that it does not damage any of the parts that it touches. It is a good idea to replace the pins with new ones because sometimes they are damaged during removal or just get worn and sloppy. You don’t want to take a chance of having them slide out while driving! Make sure to reinstall the master cylinde
