Brake Tubing

 WARNING: COPPER TUBING SHOULD NOT BE USED IN THE HYDRAULIC SYSTEM. USE ONLY SAE J526 OR J527 STEEL TUBING, OR EQUIVALENT.

NOTE: If a section of the brake tube is damaged, replace the entire section with tubing of the same type, size, shape, and length. Be careful not to kink or crack the tubing when bending it to fit the frame or rear axle forms.

NOTE: Always clean the inside of a new brake tube with clean isopropyl alcohol.

Steel tubing is used in the hydraulic lines between the brake master cylinder (2140) and the front brake tube connector and between the rear brake tube connector and the rear wheel cylinders (2261). Steel tubing is also used to connect the brake master cylinder to the rear brake hose (2282) at the rear axle (4001). Flexible hoses connect the brake tube to the disc brake calipers (2B120) and to the rear brake tube connector.

When replacing hydraulic brake tubing, hoses or connectors, tighten all connections securely. After replacement, bleed the brake system. Refer to Section 06-06.
