2009 Chevrolet Suburban 1500 Brake Caliper

You can not use any air tools to remove or tighten the guide pin bolts. Use hand tools only. You should install an open-end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the caliper guide pin bolt. You can not allow the open-end wrench to come in contact with the brake caliper. Allowing the open-end wrench to come in contact with the brake caliper will cause a pulsation when the brake is applied.

You can not place fingers in front of the caliper piston(s) in an attempt to catch or protect it when applying compressed air. The piston(s) can fly out with force and could result in serious bodily injury. The brake calipers use phenolic pistons that have stainless steel caps that contact the brake pads. Use compressed air to remove the piston from the brake caliper. When applying the clean brake fluid to the piston bores, piston seals, and pistons, only apply the brake fluid to one bore at a time. This is done to ensure that the brake caliper, seals, and pistons DO NOT become contaminated with dirt or other foreign material.

You can not use any air tools to remove or install the brake caliper bolts. Use hand tools ONLY, and install an open-end wrench to hold the caliper guide pin in line with the brake caliper while removing or installing the brake caliper bolt, can not allow the open-end wrench to come in contact with the brake caliper. Allowing the open-end wrench to come in contact with the brake caliper will cause a pulsation when the brakes are applied.

If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding. If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove the brake fluid to the midway point before proceeding. You should ensure that the copper gaskets are not attached to the brake caliper or the brake hose and can not re-use the copper gaskets, replace them with NEW.

Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected.
