Brake Hose/Line: Description and Operation
BRAKE LINES
DESCRIPTION
The brake tubes are steel with a corrosion-resistant nylon coating applied to the external surfaces.
The flex hoses used at each wheel brake are made of reinforced rubber with fittings at each end. The fitting at each brake caliper is the banjo-type and
requires a special banjo bolt and copper washers.
OPERATION - BRAKE TUBES AND HOSES
The purpose of the chassis brake tubes and flex hoses is to transfer the pressurized brake fluid developed by the master cylinder to the wheel brakes of
the vehicle. The flex hoses are made of rubber to allow for the movement of the vehicle's suspension.
INSPECTION
Brake tubing should be inspected periodically for evidence of physical damage or contact with moving or hot components.
Flexible rubber hose is used at both the front and rear wheel brakes. Inspection of the flexible brake hoses should be performed whenever the brake
system is serviced and every 7,500 miles or 12 months, whichever comes first. Inspect hydraulic brake hoses for surface cracking, scuffing, or worn
spots. If the fabric casing of the hose becomes exposed due to cracks or abrasions in the hose cover, the hose should be replaced immediately.
Eventual deterioration of the hose can take place with possible burst failure. Faulty installation can cause twisting, resulting in wheel, tire, or chassis
interference.
