Video tutorial on how to remove and lubricate the sliding pins on a disc brake assembly. Sliding pins, also known as guide pins allow your caliper to float, so when your brake pedal is applied, the braking surface on both sides of the rotor can be used. When the piston is pushed out, this basically creates a pinching against the rotor using the brake pads. Every time maintenance is done on the disc brake assembly, these pins should be cleaned and lubricated otherwise you can risk having them stick or seize. Sticking or seized pins can cause the brakes to stick on, prevent the brakes from functioning fully, and uneven wear on the pads.

Tools/Supplies Needed:
-ratchet with socket set
-wire brush
-file
-abrasive pad
-sandpaper
-small round object
-degreaser
-rag
-new slide pins
-new rubber boots
-torch
-slide hammer
-hammer
-adjustable wrench
-brake pin lubricant (used in the video is Permatex Synthetic Brake Lubricant #09125)

Procedure:
-the carrier can be removed or left in place when cleaning the pins and adding lubricant
-simply pull the pin out and give it a slight rotate which will help assist the rubber boot off
-remove the boot completely, then wipe away the old grease
-use a degreaser to clean off any residue if needed
-using a file, clean up around the boot’s sealing surface if there is a light build up of rust
-use an abrasive pad if needed to clean any dirt build up or rust on the pins
-if your pins are too far gone, then I would recommend purchasing new replacements from either the dealer, local auto parts store, or online
-using a rag and something which is able fit in the hole of the carrier, clean the old lubricant or any dirt inside
-once you are done, now apply a brake specific lubricant to the pins
-reinstall the rubber boots if they are in good condition, then push the pins back into place
-for stuck or seized, they can be removed either by the use of an adjustable wrench to rotate them, using a slide hammer, or applying heat with a propane or acetylene torch set
