  1. Raise the rear of the vehicle and support safely using jackstands.

  12.  

On easy method of separating the retainer fingers is to slip a suitably sized box wrench (usually 1 / 2 in. is suitable as it is just small than the retainer) over the cable end and down the cable until it rests on top of the retainer. Tap wrench and cable retainer backwards, as the wrench is tapped over the retainer it will depress the tabs and the retainer will begin to move back through the backing plate.

To install:

  1. Attach the cable to the brake shoe operating lever and make sure the retainer is properly seated on the backing plate.
  2.  
  3. Engage the rear cable at the connector.
