Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brake Tubes and Hoses
Double wall steel tubing is used throughout the brake hydraulic system. All brake tube fittings must be correctly flared to provide strong leakproof connections. When bending tubing to fit the underbody or rear axle contours, be careful not to kink or crack the tube.
If a section of brake tube 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.
