How to Change Rotors on a Toyota 4Runnerthumbnail
Change the rotors on your Toyota 4Runner.

The brake rotors on your Toyota 4Runner become thinner and wear out after years of service, developing imperfections such as cracks on their friction surface. A worn out rotor affects the proper operation of the brake system on your 4Runner and has to be replaced as soon as possible. You can do this job following these steps.

Difficulty:
Moderately Easy

Instructions

things you'll need:

  • Lug wrench
  • Floor jack
  • Jack stand
  • Hand siphon pump
  • C-clamp
  • Wrench set
  • Ratchet and socket set
  • Brake parts cleaner
  • Shop rag
  • Denatured alcohol
  • Clean cloth
  1. Removing the Rotor

    • 1

      Remove half the fluid from the brake master cylinder using a hand siphon pump. The master cylinder is mounted on the brake booster, a drum like unit on the firewall, driver side of the engine compartment.

    • 2

      Loosen the lugs, using a lug wrench, on the wheel assembly with the rotor you need to change.

    • 3

      Raise the wheel and tire assembly using a floor jack, and safely support it on a jack stand.

    • 4

      Remove the tire.

    • 5

      Set a C-clamp over the brake caliper with the clamp screw facing the front brake pad.

    • 6

      Tighten the C-clamp screw to push the caliper cylinder into its bore.

    • 7

      Unscrew the two brake-caliper mounting bolts using a wrench or ratchet and socket.

    • 8

      Secure the brake caliper to the vehicle's body using a wire to avoid damage to the brake hose attached to the brake caliper.

    • 9

      Remove the two mounting screws from the caliper-mounting bracket using a wrench or ratchet and socket, if you are replacing one of the rear rotors.

    • 10

      Remove the brake rotor by hand.

    Installing the Rotor

    • 1

      Remove the protective film from the friction surface of the new brake rotor using denatured alcohol and a clean cloth.

    • 2

      Clean the wheel/hub assembly with brake parts cleaner and a shop rag.

    • 3

      Set the new rotor in place on the wheel/hub assembly.

    • 4

      Install the brake caliper-mounting bracket using a wrench or ratchet and socket, if you are replacing one of the rear rotors.

    • 5

      Mount the brake caliper using a wrench or ratchet and socket.

    • 6

      Set the tire on the wheel/hub assembly and install the wheel lugs using the lug wrench.

    • 7

      Lower the vehicle.

    • 8

      Finish tightening the wheel lugs.

    • 9

      Refill the brake master cylinder with brake fluid until the level is between the Low and Full marks.

    • 10

      Depress the brake pedal several times to adjust the brake pads onto the new brake rotor.
