Brake Lines and Hoses

CAUTION: Never use copper tubing. It is subject to fatigue, cracking, and corrosion, which could result in brake tube failure.

Double wall steel tubing is used throughout the brake hydraulic system. All brake line fittings must be correctly double flared to provide strong leakproof connections. When bending tubes to fit the underbody or rear axle contours, be careful not to kink or crack the tube.

If a section of brake line is damaged, an entire new section must be installed with a tube of the same type, size, shape and length.

When installing new hydraulic brake tubing, hoses, or connectors, tighten all connections securely. After installation, bleed the brake system. For additional information, refer to BRAKE SYSTEM-GENERAL INFORMATION .

The wet appearance on the outer cover of rubber brake hoses is called "sweating." This is a normal condition for neoprene rayon braid hose and is not a sign of leakage or cause for the installation of a new hose.
