    Wheel assembly
     
    Brake drum detent (retaining) screw
     
    Drum from the axle
     

  4.  
  5. If difficulty is encountered in removing the drum, perform the following:
    1. Verify the parking brake is released.
    2.  
    3. Loosen the parking brake cable.
    4.  
    5. Remove the access hole plug from the backing plate and move the parking brake lever until the lever stop rests on the brake shoe.
    6.  
    7. If necessary, turn the adjuster so that it draws in to allow more clearance between the shoe and drum.
    8.  

  6.  

To install:

  1. Inspect all parts. Check the drum for cracks or excessive wear.
  2.  
  3. Turn the adjuster until it is drawn all the way in to the stop. Check that the adjuster turns freely. The nut must NOT lock at the end of the adjuster. Check that the parking brake lever stops are against the edge of the shoe web.
  4.  
  5. Install or connect the following:

    Brake drum and detent screw
     
    Wheel assembly
     

  6.  
  7. Apply the foot brake at least 10 times until clicking of the adjustment actuator can no longer be heard. This procedure will automatically adjust the clearance between the shoe and drum.
  8.  

All vehicles except Sebring Convertible, are equipped with rear wheel, 2-shoe leading/trailing, internal expanding type of drum brakes with automatic self-adjuster mechanisms. The automatic self-adjuster mechanisms used on these vehicles are new designs and function differently than the screw type adjusters used in the past. These new self-adjusters are still actuated each time the vehicle's service brakes are applied. The new adjusters are located directly below the wheel cylinders.

The Sebring Convertible's rear wheel drum brake is a 2-shoe leading/trailing internal expanding type with an automatic self-adjuster mechanism. The automatic self-adjuster mechanism used on this vehicle is the screw type adjuster. The self-adjuster mechanism is actuated each time the vehicle service brakes are applied. Although, in the event that the brake shoes are replaced, it is advisable to make the initial adjustment manually to speed up the initial adjustment time. The initial adjustment procedure must be done prior to driving the vehicle.

  1. Remove the rear wheel assembly.
  2.  
  3. For all vehicles, except Sebring Convertible, use the following procedure:
    1. Locate and remove the rubber plug from the brake support plate (backing plate).
    2.  
    3. Insert a brake adjuster tool or similarly shaped pry tool through the automatic adjuster access hole and engage the teeth on the adjuster wheel. Rotate the adjuster wheel so it is moved toward the front of the vehicle. Continue moving the adjuster until it stops; this will back off the adjustment of the rear brake shoes.

  5. For the Sebring Convertible, use the following procedure for releasing the self-adjusting mechanism:
    1. Locate and remove the rubber plug from the brake support plate (backing plate).
    2.  
    3. Insert a brake adjuster tool or similarly shaped pry tool through the automatic adjuster access hole and carefully push the adjuster actuating lever out of engagement with the adjuster starwheel. While holding the lever away from the starwheel, insert a second pry tool through the access hole and engage the teeth on the adjuster wheel. Rotate the adjuster wheel upward away from the ground; this will back off the adjustment of the rear brake shoes.

Inspect the brake drums for cracks or signs of overheating. Measure the drum run-out and diameter. If not to specification, resurface the drum. Run-out should not exceed 0.006 inch (0.15mm). The diameter variation (oval shape) of the drum braking surface must not exceed either 0.0025 inch (0.064mm) in 30 degrees rotation, or 0.0035 inch (0.089mm) in 360 degrees rotation. All brake drums are marked with the maximum allowable brake drum diameter on the face of the drum.

  1. Install the rear brake drum onto the hub assembly.
  2.  
  3. Reinstall the wheel and tire. Torque the lug nuts in a star pattern sequence to about 45 ft. lbs. (61 Nm); then, repeat the pattern and final torque to 95-100 ft. lbs. (129-135 Nm).
  4.  
  5. Properly adjust the rear brakes.
  6.  
  7. Road test vehicle to check for proper brake operation.
