Why use double banjo bolts on motorcycles?
Double banjo bolts are particularly useful for motorcycles where two full-length brake lines are run from the master cylinder to each front brake caliper. This improves braking performance and simplifies the brake line setup.
-
What is the difference between a standard double banjo bolt and a double banjo bolt with a bleeder?
- Standard double banjo bolts are used to connect two fluid lines in hydraulic systems.
- Double banjo bolt bleeders have an integrated bleed valve, making it easier to remove air from the brake system without needing to bleed from the caliper.

What materials are double banjo bolts made from?
Most double banjo bolts are made from high-quality stainless steel to ensure durability, corrosion resistance, and reliability in high-pressure brake and hydraulic systems.
