GM 3487476 Caliper Assembly Pkg, Lh

Before removing the brake caliper, unscrew the lid of the brake fluid container and pump out about 2/3 of the brake fluid and then, discard it. You should still not remove this nut but simply slacken the nut on the front wheel, after that set down the car and support the front part of it using the jack stands. To have guidance, work on one side at a time Remove the front wheel. Apply pressure to the piston to the bore with the assistance of the C-clamp so that there is forced the fluid back into the master cylinder but also to ensure that it does not spill all over; for lack of the C-clamp, one may be forced to use the screwdriver after having removed the caliper. If altering or removing the caliper, unbolt the brake caliper inlet hose nipple but do not disconnect it if not necessary. Now it is necessary to remove the two mounting bolts of the caliper with the sleeves and bushings; it is suggested to keep the mounting bolts and reject the others since they should be new to be used during the assembling. If having the pads changed then suspend the caliper to the upper A-arm with wire so that the brake hose does not get damaged. If no C-clamp was applied earlier, push down the piston with screwdrivers or pry bar. For fit up, lubricate the new sleeves and bushings with the silicone grease, fit the caliper and mounting bolts to the correct torque value while the gap between the caliper housing and bracket should be within limits so that there can be free movement. Tighten the caliper mounting bolts to the torque mentioned above, if the brake inlet hose was disconnected, connect it back and bleed the brake system. Last, mount the wheels and drop the vehicle, as well as properly torque the lugs nuts in that required amount.

Remove the piston, balance spring, and actuator screw, then take out the seal and thrust washer, noting their orientation for reassembly.
