Durable Construction and Precise Fitment

Both ends of the hose feature treated steel fittings—banjo type on one end and female on the other—ensuring a secure and leak-free connection. The hose’s flexible design accommodates vehicle movement while maintaining brake fluid integrity. Included gaskets help achieve a tight seal during installation.

Common Applications and Problem Resolution

• Replaces worn or cracked brake hydraulic hoses causing fluid leaks

Installation Notes and Tips

When installing the Dorman H622321 brake hydraulic hose, ensure all old hose components and seals are fully removed. Use the included gaskets to secure leak-free connections at both ends. The banjo fitting end requires a pinch bolt attachment with a 10 mm thread diameter, while the female fitting end uses an inverted flare connection with an M10 x 1.0 inside diameter. Verify hose routing matches the original to avoid kinks or interference. Bleed the brake system thoroughly after installation to remove air and restore proper brake function.
