2009 Chevrolet Suburban 1500 Brake Pad Set

You should use an open-end wrench to hold the caliper guide pin while tightening the guide pin bolt to 38 Nm(28 lb-ft).

You can not use any air tools to remove the guide pin bolts. You should 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 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 should 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.

You should install 2 large C-clamps over the top of the caliper housing and against the back of the outboard pad, slowly tighten the C-clamp until the pistons are pushed completely into the caliper bores, and remove the C-clamp from the caliper.

You should select a smooth road with little or no traffic, accelerate the vehicle to 48 km/h (30 mph), use moderate to firm pressure and apply the brakes to bring the vehicle to a stop. Do not allow the brakes to lock and repeat steps 2 and 3 until approximately 20 stops have been completed. Allow sufficient cooling periods between stops to properly burnish the brake pads and rotors.
