A: Inspect rubber brake hoses every six months for damage. For faulty hoses, replacement is necessary. For the front brake hose: disconnect the brake line from the hose fitting, remove the U-clip and hose from the bracket. At the caliper end, remove the bolt and hose. When installing, use new copper washers and lubricate bolt threads. Attach hose to caliper without twisting and secure with U-clip. For the rear brake hose: disconnect at the frame bracket, remove the U-clip, disconnect hydraulic lines, and remove the hose. Install the new hose, secure junction block, and use U-clips. Attach steel line fittings carefully. After replacements, refill and bleed the system. For metal brake lines, use proper steel brake lines, not copper. If replacing, use prefabricated lines or the recommended tubing and fittings, flare ends, and shape as needed.
