Installation Notes and Tips

Confirm drum diameter, shoe width, and FMSI match before installation. Inspect the parking brake drum for scoring, heat spots, or excessive wear, since drum condition affects shoe contact and braking performance. Clean the backing plate and verify all contact points are in good condition before assembling the rear parking brake shoes. For best results, compare the removed shoe to the Z852 and verify vehicle-specific fitment for your Ford E-150, Ford Econoline, Dodge Durango, or Dodge Ram 1500 application.
