Brake Caliper Banjo Bolt
The Disc Brake Caliper Banjo Bolt 7/16"-20 x 1" 290-032783 is a replacement hydraulic brake fitting bolt used on compatible EZ Loader trailer disc brake caliper setups. This EZ Loader brake caliper banjo bolt helps secure the banjo block or brake line fitting at the caliper connection point.
This banjo bolt is used with compatible 10" and 12" trailer disc brake calipers where the brake line connection uses a banjo-style block or fitting. A damaged, missing, corroded, or incorrect banjo bolt can cause brake fluid leaks, poor brake pressure, or trouble sealing the brake line connection properly.
Although this is a small part, it is important to the hydraulic brake system. The banjo bolt must match the caliper, banjo block, brake line fitting, thread size, sealing washers, and original EZ Loader brake configuration.
This is not a brake caliper, rotor, pad, or actuator. It is a hydraulic brake connection bolt used at the caliper fitting area.

Typical EZ Loader Trailer Applications
This banjo bolt is commonly used on compatible EZ Loader boat trailers equipped with hydraulic disc brake calipers. It may apply where the brake line connection at the caliper uses a banjo block or banjo-style fitting.
Always compare the part number, thread size, bolt length, caliper style, brake line fitting, banjo block, sealing washers, and trailer VIN before ordering.
Why This Small Brake Part Matters
The banjo bolt helps secure the hydraulic brake fitting at the caliper. If the bolt is damaged, incorrect, missing, or does not seal properly with the correct washers, the trailer may lose brake fluid or fail to build proper hydraulic brake pressure at that caliper.
Installation Considerations
- Confirm the caliper uses a compatible banjo bolt and banjo block setup before ordering.
- Inspect the banjo block, brake line, sealing washers, and caliper port during service.
- Use the correct sealing washers when required by the brake fitting setup.
- Replace damaged or contaminated brake fluid as needed.
- Make sure all hydraulic brake fittings seal correctly before towing.
- Bleed the brake system after opening the hydraulic brake line.
- After service, test the trailer brakes in a safe area before normal road use.
Fitment Guidance
This is not a universal hydraulic brake bolt. Correct fitment depends on the trailer model, VIN, caliper style, brake line fitting, banjo block setup, sealing washers, thread size, bolt length, and existing brake hardware.
- Confirm part number 290-032783 when possible.
- Confirm the thread size is 7/16"-20.
- Confirm the bolt length is 1".
- Compare the old banjo bolt to the new part before ordering.
- Check the caliper port, banjo block, and sealing washer setup.
- Send photos if you are unsure about fitment.

Real-World Insight
Brake fluid leaks at the caliper connection are often caused by the wrong bolt, damaged sealing washers, a damaged banjo block, stripped threads, or a fitting that is not seated correctly. When servicing this area, inspect the full hydraulic connection and bleed the brake system before returning the trailer to service.
