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 Hoses and Tubes
- 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 tube fittings must be correctly double flared to provide strong, leakproof connections. When bending tubing to fit underbody or rear axle contours, be careful not to kink or crack the tube.
If a section of brake tube is damaged, the entire section must be installed new with a tube of the same type, size, shape and length.
When installing the hydraulic brake tubing, hoses, or connectors, tighten all connections to specifications. After installation, bleed the brake system. See BRAKE SYSTEM BLEEDING - CONVENTIONAL BRAKE SYSTEM .
Install a new flexible brake hose if the hose shows signs of softening, cracking or other damage.
When installing a new brake hose, position the hose to avoid contact with other vehicle components.
