Pair of weld-on brake backing plates (brake flanges) designed for 5,200 lb, 6,000 lb, and 7,000 lb B-Type trailer axles.These flanges provide the mounting surface required to install electric or hydraulic drum brake assemblies.
This listing includes two (2) brake flanges — enough for one complete axle.
| Component | Quantity |
| 5-Hole Brake Backing Plate / Flange | 2 |
| Specification | Detail |
| Mounting Holes | 5 Bolt Pattern |
| Pilot Hole Diameter | 2.56" |
| Axle Compatibility | 5,200 lb / 6,000 lb / 7,000 lb B Type Axles |
| Installation Type | Weld-On |
Brake flanges (backing plates) are welded to the axle tube to provide a secure mounting surface for trailer brake assemblies.The 2.56" pilot hole centers the brake assembly and ensures proper alignment with the hub and drum.
When adding brakes to an idler axle or replacing damaged flanges, confirm axle rating, brake size (typically 12" x 2" for 5.2K–7K B-Type),bolt pattern, and pilot diameter before installation.Professional welding and proper alignment are critical for safe brake operation.
IMPORTANT: Flanges must be professionally welded to compatible axle tubing.Verify pilot diameter, bolt pattern, and axle rating before installation.
