Overview

This banjo bolt and washer kit is used at compatible hydraulic disc brake caliper connections where brake fluid passes through the banjo bolt and seals against copper washers. The kit includes one UFP 32307U 7/16-20 x 1" banjo bolt and two UFP 32230U copper sealing washers.

Best used when the existing brake caliper connection matches the 7/16-20 thread size, 1" bolt length, and copper washer sealing arrangement.

R&P Service Insight

Banjo connections depend on clean sealing surfaces, correct washer placement, and proper installation. Reusing old crushed or damaged copper washers can lead to brake fluid seepage.

Washer Placement: Banjo-style connections typically use one copper washer on each side of the banjo fitting or block.
Leak Prevention: Inspect sealing faces for debris, grooves, corrosion, or damage before tightening.
Brake Safety: After service, bleed the brake system and check carefully for leaks before towing.

R&P Knowledge Hub

Compatibility: Use this kit only where a 7/16-20 x 1" banjo bolt and 32230U-style copper washers match the brake caliper connection.

Vehicle / System Fit: Trailer hydraulic disc brake caliper banjo connection hardware.

Installation Notes: Confirm the existing bolt size, thread pitch, fitting style, and washer count before installation. This kit does not include the banjo block.

Performance Insight: The banjo bolt allows brake fluid to pass through the fastener while the copper washers compress against the sealing surfaces to help prevent hydraulic leaks.
