Pair -12-1/4"x3-3/8 Genuine Dexter Electric Brake Backing Plate 10K GD Trailer (K23-450-00 + K23-451-00)

Features:
- This brake is rated to a maximum capacity of 10,000 lbs. per pair and is typically found on 9,000# to 10,000# trailer axles (Yellow Wire Magnet)

7 Bolt Mounting

- SELF ADJUSTING FEATURE: Forward Self Adjusting (FSA) feature adjusts the brakes on both forward and reverse stops. Brake adjustment occurs when lining wear results in enough gap between the shoes and the brake drum surface. This added clearance will allow the adjuster mechanism to rotate the screw assembly at the bottom of the brake. That action expands the distance between the shoes and thus closes the gap to the drum surface.

and ONE K23-451-00  (023-450-00 or 23-450)
