1997 Toyota 4Runner Replace Brake Pads
The 1997 Toyota 4Runner is equipped with disc front brakes that use hydraulic pistons to press two pads against a circular rotor. This action creates friction, which slows the front wheels to stop the vehicle. This friction also causes the pads to eventually wear away, however. If you hear a squealing sound when you press the brake pedal, your vehicle's brake pads have worn down and you need to replace them. Replacing the brake pads on your 4Runner is a simple procedure that should take one hour or less.
Replace Brake Pads
- Loosen the lug nuts of the wheel where the brake pads need replacement. Use a jack to raise the front of the vehicle. Support both sides of the raised vehicle with jack stands.
- Remove the lug nuts, and take off the wheels.
- Place a drip pan under the brake assembly. Spray the entire brake assembly with brake cleaner to clean off dangerous brake dust. Allow the assembly to dry.
- Remove the wire pin retainer clip from the holes in both pads. Use a pair of pliers or your fingers to pull out the lower pad retaining pin. Remove the anti-rattle spring. This is the flat piece of metal covering the opening in the caliper. Remove the upper pad retaining pin, and pull out the outer brake pad.
- Use a large screwdriver or similar tool to push the piston back into the bore.
- Coat the back of the new outer pad with anti-squeal compound. This should come with the new pads. Install the shim on the pad, and coat the back of the shim with grease. Insert the new outer pad into caliper.
- Remove the inner pad, and push back the piston with a screwdriver. Repeat Step 6 for the inner pad.
- Replace the upper pad retaining pin. Replace the anti-rattle spring. Insert the lower pad retaining pin. Insert the wire pin retainer clip into the holes on the retaining pins.
- Replace the wheel and lug nuts. Lower the vehicle, and tighten the lug nuts. Repeat the procedure on the opposite side.
Tips & Warnings
- Inspect the rotors for wear and damage while you have the wheel off. It's usually a good idea to have the rotors machined when you replace the brake pads. If you see grooves in the rotors, you should definitely have them serviced.
