12" x 2" Trailer Brake Drum – 8 on 6.5" Bolt Pattern
Part Number: 92865-1
Heavy-duty trailer brake drum designed for standard 12" x 2" electric brake assemblies with 8-lug wheels on a 6.5" bolt circle. Ideal for replacement on 5,200–7,000 lb axle setups requiring consistent braking performance.
R&P Knowledge Hub
Compatibility: Matches 12" x 2" electric brake assemblies commonly found on 5.2K–7K trailer axles.
Bolt Pattern: 8 on 6.5" is standard for heavy-duty trailer hubs—verify before ordering.
Important: This is a drum only. Bearings, races, seals, and caps must be sourced separately or reused if serviceable.
Performance Insight: Drum wear or heat scoring reduces braking efficiency—replacement restores proper contact and stopping power.
R&P Service Insight
Brake drums typically wear gradually through heat cycles and friction. Most failures are not sudden—but reduced braking performance is a clear indicator of replacement need.
- Heat Wear: Repeated braking creates glazing and internal scoring
- Surface Deformation: Out-of-round drums reduce braking efficiency
- Corrosion: Moisture exposure leads to internal rust and uneven braking
