The metal call inside the caliper, the caliper piston, should be pried expanded To admit for the thicker brake pads.
The brake pads on the 1999 Chevy Silverado 4x4 hold built-in wear indicators. The indicators are metal clips that assemble contact with the Silverado's disc-brake rotors when the brake pads accept reached a calm of wear that warrants pad replacement. Prolonged apply of worn brake pads can bob to expressing and irreparable damage to the rotors. Transform the Chevy Silverado brake pads every 50,000 miles (as recommended by Habitual Motors), or as soon as you hear the scraping of the indicators on the rotors, whichever occurs elementary.
Instructions
1. Loosen with a lug wrench the lug nuts on the wheels on which you thirst for to modify the brake pads. Levy the jack under the frame near the spin hardy and lift the tires at least three inches off the ground. Lower the Silverado onto at least two jack stands. Remove the lug nuts and accept the wheels off.
Place the caliper over the pads in the caliper bridge and screw in the slide bolts with the socket and ratchet.7. Replace the wheel on the wheel bolts. Suspend the caliper above the trundle hub with a bungee cord.
3. Pry the brake pads from the caliper bridge with a flat-head screwdriver. Test the rotor for damage and momentous wear. Warped rotors should be replaced now.
4. Put the 10-mm socket wrench over the brake bleed valve bolt. The bolt is located halfway between the two caliper slide bolts. Place a drip pan under the caliper to capture the brake fluid. Turn the bolt 1/4 turn to open the valve.
5. Place the locking pliers over the caliper piston and the back side of the caliper from which the piston extends. Squeeze the piston into the side of the caliper. Remove the pliers after the piston has been fully opened, that is, depressed within the caliper. Close the valve.
6. Place the new brake pads into the caliper bridge. The pads fit into the slots on either side of the brake rotor.2. Remove the caliper slide bolts with a 13-mm socket and ratchet. The bolts are located on the back side of the caliper, which straddles the brake rotor. Lift the caliper from the rotor and brake pads resting inside the slots of the caliper bridge.
Screw on the lug nuts by hand. Lift the truck with the jack and move the jack stands from beneath the axles. Lower the Silverado's tires to the ground and tighten the lugs with the lug wrench. Repeat the process for each additional set of brake pads you need to replace.
8. Start the engine. Press the brake pedal slowly to the floor, release it, and depress the pedal again. Pull the hood release lever under the dashboard on the driver's side of the truck and move to the front of the vehicle.
9. Lift the hood and prop it open. Remove the master cylinder cap, which is located in the back of the engine compartment to the right of the engine. Place a funnel inside the reservoir and fill the container with brake fluid. Replace the master cylinder cap and close the hood.
