1999 Toyota 4Runner Brake Pad Installation
The 1999 Toyota 4Runner comes standard with front-wheel, anti-lock disc brakes. The braking system comprises brake pads, which are squeezed against the front rotors to slow, and eventually stop, the 4Runner, during braking. The brake pad material wears thin after miles of stress and heat and should be replaced, as recommended by Toyota, every 40,000 miles. You can have the pads replaced by a professional brake mechanic, or you can save money by performing the maintenance yourself.
Brake Pad Installation
- Park the 4Runner on a flat surface. Place tire blocks behind the front wheels. Loosen the lug nuts with the lug wrench. Place the jack under the frame of the vehicle, and lift the front tires off the ground, at least three inches. Place jack stands under the axles, and lower the Toyota onto the stands.
- Remove the lug nuts, and take off the wheels. Place the C-clamp onto the right brake caliper. The caliper houses the brake pads and fits around the rotor. Place the clamp on the outside of the caliper and against the inner-most brake pad. Crank the clamp handle, to squeeze the pad against the side of the caliper. The caliper piston will be depressed into the side of the caliper, to allow you to remove the brake pads and provide room for the thicker, new brake pads.
- Remove the C-clamp. Remove the two caliper slide bolts on the back side of the caliper, with a 14-mm wrench. Lift the caliper and brake pads from the rotor.
- Slide the two brake pads from the caliper. Inspect the caliper and rotor for wear or damage. Heavily scored rotors should be replaced.
- Apply brake grease to the back sides of the new brake pads. Slide the pads into the caliper. The greased sides should face outward. Replace the caliper over the rotor, and screw in the caliper bolts. Replace the wheel onto the wheel bolts, and screw on the lug nuts, by hand.
- Move to the left brake, and repeat Steps 2 through 5, to replace the brake pads. Replace the right wheel, and screw on the lug nuts. Lift the 4Runner, with the jack, and remove the jack stands. Lower the tires to the ground, and tighten the lugs with the lug wrench.
- Start the engine. Press the brake pedal, repeatedly, until the pedal response returns to normal. Pull the hood release lever under the dashboard on the driver's side, and move to the front of the vehicle.
- Lift the hood. Remove the master cylinder cap, located on the right side of the Toyota engine. Place a funnel into the container, and fill the reservoir with brake fluid, as needed. Remove the funnel, and replace the cap. Close the 4Runner hood.
