# Preparation For Brake Pad Replacement # Remove the Wheel # Unbolt the Caliper # Remove the Old Brake Pads # Compress the Brake Piston # Re-Install the Brake Caliper
Remove the wheel, and brake assembly (4 bolts on back of calipers) be sure to hang the brake piston so that it does not hang by the brake line, remove the rotor, clean and inspect all parts including brake pads. Open the brake fluid resivoir, get a c-clamp or a piston depressor to push the brake piston back in. This should take about 15 seconds to SLOWLY push the piston in. Re-assemble brakes and repeat on other side.
You will need a jack to lift the truck, and jack stands to support the truck while it is being worked on. A lug wrench to remove the wheel. A 3/8" hex key wrench, or a 3/8" hex key socket. A pry to back the pads off a little for easier removal. If removing totally from the truck a wrench to remove the banjo bolt to disconnect the brake hose which has a copper washer gaskets on each side. If just replacing pads do not remove hoes, you will need a 8" c clamp to compress the caliper piston, using the old pad as a backer for the c clamp. You may have to remove some brake fluid from the reservoir as it will fill as you compress the piston. Once both calipers are re padded and mounted on truck push brake pedal two or three times to readjust calipers. Check and refill brake fluid level.
Buy a rear brake cylinder re-winder $60. However, you can also struggle with a C-clamp and needle nose pliers, pressure - turn, pressure-turn, pressure - turn. The rear pistons rotate as brake pressure is applied which allow them to lock with the parking brake.
General guidelines: Remove tire. Right side first. Do one at a time. Remove caliper Remove rotor. Re-surface or replace Compress piston in caliper Remove old brake pads Install new brake pads Replace rotor Re-install tire Gently pump up brake pedal until you get full pedal You are done
It helps re-fit to slide it back a fraction.

The rear brake calipers on the Freestyle contain an internal spiral mechanical advance, part of the emergency brake system. The pistons cannot be compressed in the usual way using a C-clamp or piston compression tool. DO NOT ATTEMPT TO FORCE THEM! You may damage the internal parts. The pistons must be rotated to retract the spiral mechanism. The driver's side is rotated clockwise and the passenger side is rotated counterclockwise. Look for the arrow near the piston bore on the caliper forging. Rotation is best accomplished with a spanner wrench tool available at good auto parts stores. It is a 3/8" square drive (standard socket ratchet) cube, Lisle Tool Corp. part #28600. Open the bleed port before turning the piston to relieve hydraulic pressure. A length of Ø1/4" ID clear tubing on the bleed barb is useful for directing the fluid into a receptacle. After the piston is fully retracted, make sure the piston spanner grooves are vertically aligned, as the top groove is clearance for a small pin on the brake pad plate. NOTE: If your pads are extremely worn, the spriral may become disengaged internally. In this case, you must apply significant inward force AS YOU TURN THE PISTON to make it re-engage. This is virtually impossible to do without removing the caliper from the car and mounting it in a vise. You will have to bleed the brake lines after reassembly, but it is still less work than fighting a flopping caliper still tethered to the car.
