How to Change the Brakes on a Toyota Avalon
Replacing the Brakes on a Toyota Avalon (brake calipers image by Tom Oliveira from Fotolia.com)

The braking system on the Toyota Avalon includes the brake booster, master cylinder, brake caliper, disc brake pads and the brake rotor. The Avalon comes equipped with disc brakes on all four wheels. When the brake pedal is pushed in, the brake booster pressurises the brake fluid inside of the master cylinder. The brake fluid then flows through the brake lines to the brake calipers. The calipers then compress the brake pads to the brake rotors to stop the car. Change the brake pads at least every 50,000 miles as recommended by Toyota.

Instructions

  1. 1

    Park the Toyota Avalon on a level surface and apply the parking brake.

  2. 2

    Loosen each of the lug nuts from the front wheels with a tire tool.

  3. 3

    Jack the front of the Toyota Avalon up and slide the jack stands under the proper front jacking points. Lower the jack so that the Avalon cones to a safe and secure stop on top of the stands.

  4. 4

    Remove all of the lug nuts from the front wheels. Pull the front wheels off and place them flat down near each side of the car.

  5. 5

    Locate the two upper and lower 13mm slide bolts on the back of the front driver side brake caliper. Loosen and remove the two slide bolts with a ratchet and a 13-mm socket.

  6. 6

    Slide the brake caliper off of the caliper bracket and hang it to one of the steering components behind the wheel hub assembly with a small piece of rope. Never allow the caliper to hang by the brake line.

  7. 7

    Pry the inner brake pad out of the caliper with a flat head screwdriver. Position the c-clamp around the outer brake pad and the back side of the brake caliper. Compress the outer brake pad until the caliper piston is completely inside of the caliper. Remove the c-clamp and the outer brake pad from the caliper.

  8. 8

    Insert the new brake pads into the metal retaining clips of the brake caliper. Inspect the brake rotor for wear. If the wear is excessive, replace the rotor with a new rotor. If the wear is minimal, have the rotor turned by a machine shop or auto repair shop.

  9. 9

    Remove the rope from the caliper. Lower the caliper back over the rotor onto the caliper bracket. Screw the two slide bolts back through the back of the caliper. Tighten the bolts with the ratchet and the 13-mm socket.

  10. 10

    Slide the wheel back on and screw the lug nuts back onto the studs. Tighten the lug nuts until the wheel begins to turn. Move to the other four wheels and follow the same steps as outlined above for replacing the brake pads. Once the pads have been replaced, make sure that all of the wheels are secured to each wheel hub with the lug nuts. Jack the Toyota Avalon back up and remove the stands. Lower the car to the ground and remove the jack.

  11. 11

    Crank the engine and push the brake pedal in and out five or six times to seat the new brake pads to the proper distance from the sides of the brake rotors. Turn the engine off.

Tips and warnings

  • Never install new brake pads to worn brake rotors. This can cause dangerous uneven braking.
  • Use caution when working under a vehicle that is on jack stands.
