R&P Service Insight
Banjo connections depend on the correct bolt thread, correct fitting style, and properly compressed sealing washers. Reusing old copper washers can increase the chance of seepage or a weak seal.
- Confirm Thread Size: Match the 7/16-20 bolt thread to the caliper before installation.
- Use Fresh Washers: Copper washers are intended to crush and seal at the fitting faces.
- Check for Leaks: After installation and bleeding, inspect the connection carefully under brake pressure.

R&P Repair Insight
If a caliper banjo connection is seeping fluid, inspect the bolt, block, washers, and caliper sealing surfaces. A damaged sealing surface, incorrect washer placement, or mismatched bolt can prevent a safe hydraulic seal.
- Washer Placement: A copper washer is typically used on each side of the banjo fitting block.
- Surface Check: Clean and inspect the caliper face and banjo fitting face before assembly.
- System Check: Bleed the hydraulic brake system and verify proper brake operation after service.
