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 Knowledge Hub

Compatibility: This kit is intended for compatible trailer disc brake caliper applications that use the 32307U 7/16-20 x 1" banjo bolt, 32275U brass fitting block, and 32230U copper washers.

Vehicle / System Fit: Used at the hydraulic brake line to disc brake caliper connection on matching trailer brake systems.

Installation Notes: Confirm the brake line fitting, caliper banjo port, bolt thread, and washer placement before tightening. Brake systems should be bled and checked for leaks after service.

Performance Insight: The banjo bolt routes brake fluid through the fitting while the copper washers create the sealing surfaces on each side of the banjo block.

Brand & Fitment Note

Selling Brand: R&P Carriages curated hydraulic brake hardware kit using the listed component part numbers.

Application Reference: Dexter and UFP references are used for fitment guidance only where the brake caliper setup, thread size, and fitting style match.

What This Means: This listing is for a complete banjo connection hardware kit, not a guaranteed OEM-branded assembly unless specifically stated on packaging or order documentation.

Before Ordering: Verify bolt thread, bolt length, washer size, fitting style, brake line connection, caliper type, and included components before installation.

R&P Repair Insight

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.
