The caliper slide bolt, or pin bolt, is the lowermost bolt on a brake caliper. The slide bolt holds the caliper to the caliper mounting bracket. When you remove this bolt, the caliper will swing open from the bottom, giving you easy access to the brake pads. On some vehicles, this is the only way to remove the pads, so it's necessary to know how to remove it.

Find the correct-size socket for the pin bolt. All vehicles have different sizes for the caliper slide bolt. Locate the correct one for your vehicle. The size should be listed in your vehicle's service manual. Your other option is to use trial and error to fit the socket.

Turn the slide bolt counterclockwise to remove it. It may take a little effort, but these bolts are typically not torqued to more than 25 lbs-ft, so you should be able to remove them fairly easily.
