• Trailer Brake Backing Plate Flange: This backing plate flange is designed for use on 5,200#, 6,000#, and 7,000# axle trailers with 3-1/8" inner hole diameter and 5 bolt mounting pattern. It measures 4-1/4" width, 4-1/2" height, 5" corner to corner, and 1/4" thick. The 3-1/8" inner hole diameter is compatible with 3/8" bolts, and the 2-1/8" spacing between mounting holes is standard for most trailer brakes.
• Round 5 Bolt Flange: The round 5 bolt flange is commonly used on 5200#, 6000#, and 7000# axles with 12"x 2" drum brakes. It features a 5 bolt mounting pattern and a round shape that provides a secure connection for the brake shoes.
• 7" and 10" Electric Drum Brakes: The 7" and 10" electric drum brakes used on modern trailers typically use the same standard 4 bolt square flange as the round 5 bolt flange. This flange provides a reliable and durable connection for the brake shoes and is compatible with various trailer brake systems.
• Mounting Brackets: It's important to use the appropriate mounting brackets when installing trailer brake backing plates and flanges. The mounting brackets should be designed to fit the specific trailer brake system and should be properly secured to the trailer frame.
• Safety: Trailer brakes are essential for the safety of towing and braking. It's important to ensure that the trailer brake system is properly installed, maintained, and operated according to the manufacturer's instructions to prevent accidents and injuries.
