  1. Step 1: Removing the Wheels (1:10)
    • Use a 19mm socket to remove the lug nut covers.
    • Loosen the lug nuts.
    • Raise the vehicle.
    • Remove the lug nuts and the wheel.
  2. Step 2: Removing the Brakes (1:39)
    • Spray them with penetrating oil.
    • Remove the locking tabs around the bolts.
    • Hit the brake on the front with a hammer to loosen it. Pry with a screwdriver once loosened.
    • Use vise-grips to lock on to the spring. Pull the spring out and down and remember what spring goes where.
    • Remove the other spring the same way as the last.
    • Pull the lever down and pull the lever across from it off.
    • Hold the back of the pin that holds on the shoes. Using the vise-grips push and twist the other side. Do the same with the other pin.
    • Take the brake shoes off.
    • Make sure there is not a leak near the wheel cylinder.
  3. Step 3: Taking the Brakes Apart (6:56)
    • Separate the shoes
    • Pull the adjuster from the shoes.
    • Clean the threads on the adjuster and coat with anti-seize.
    • Make sure it spins easily.
  4. Step 4: Preparing the New Brakes (8:07)
    • Match up the old springs with the news springs.
    • The larger shoe is the rear shoe.
    • Attach the shoes with the spring and adjuster.
    • Put anti-seize on all the places the shoes contact.
  5. Step 5: Installing New Brakes (9:16)
    • Put the emergency brake bracket into the triangle slot on the brake shoes.
    • Put the shoes on to the wheel
    • Put the pins in through the back of the shoes.
