Replace the brake pipe using J 45405 (J 45405) Pipe Flaring Tool Kit and practice brake fluid safety measures while working with double-walled steel brake pipes to avoid system failure. First check the damaged brake pipe section and unlatch it from its retainers. To replace the brake pipe use its length plus 6.35 mm (0.250 in) of additional flare length, which requires 0.250 inches (6.35 millimeters) of flare space to terminate 3/16 inch (4.76 millimeter) diameter pipe. Use the J 45405 pipe cutter to produce a precise cut exactly at the measured length on the brake pipe. Apply proper brake pipe sizes and tube nuts before using the J 45405 coating stripping tool to remove nylon coating from flare points. Use built-in kit tools to chamfer both pipe diameters for smooth connections. Begin by setting up the tube nuts then cleaning all particles from the pipe and die tool J 45405 before using tools to flare the pipe. Put the prepared pipe end into the dies then fasten the clamping screw and create the flare through the forming mandrel. Examine the flare after forming to confirm that its dimensions match industry standards for 4.76 mm (3/16 inch) pipes. The flare should maintain a diameter range from 7.10 to 7.28 mm (0.279 to 0.283 inches). Flare the pipe according to specifications then install it with unions while keeping space of 19mm (3/4in). Secure both ends to retaining hardware before bleding the brakes and checking for leaks during engine run.

Before starting work raise your vehicle and place supports under it. After removing the tire from the rear wheel you can begin replacing the brake hose. Put a rubber cover on the brake pipe fitting and cleanse it after removing any dust that collects on both components. Hold the hose fitting with an additional wrench to remove the brake pipe connection from the brake hose without harming the brake pipe components. Take out the brake hose from the bracket by removing its retaining clip from the mounting bracket. Take off the brake hose to caliper bolt from the brake caliper before detaching the brake hose from the brake caliper. Then remove both the brake hose and discard its attached copper brake hose gaskets. Place the brake hose into the vehicle before adding new copper gaskets and bolt the brake hose to its position. Grasp the brake caliper during installation of the brake hose to caliper bolt and tighten it to 54 nm (40 ft. Lbs.). Mount the brake hose on the bracket under vehicle weight while keeping bends out of the line to match the bracket notch. Put the retainer in place on the hose fitting at the bracket. Then disconnect the rubber cap or plug from end of brake pipe fitting and join it with brake hose by supporting with a back up wrench before tightening to 18 nm (13 ft. Lbs). Put back the rear tire and wheel parts while keeping the hose away from suspension components; adjust if the hose touches any parts. The last step is to drain the hydraulic brake lines and lower the vehicle.

Inspect the flare for correct shape and diameter.

Follow safety precautions regarding brake fluid irritants and use double-walled steel brake pipes to prevent system failure.

Bleed the hydraulic brake system and lower the vehicle.

Remove the rubber cap or plug from the exposed brake pipe fitting end.
