Flex Hose, Rear

To repair the rear brake hose start with lifting the vehicle and placing supports under it. Then take off the wheel and tire unit. Clear the brake hose and brake pipe connectors of soil before placing rubber covers over the open pipe ends to stop fluid leakage and contamination. You should use a back up wrench at the hose end to detach the brake pipe from the hose assembly and put a cap on the fitting. Detach the brake hose retaining clip from its bracket to take out the brake hose from its position. Take out the brake caliper bolt from the caliper to remove it. Then disconnect the brake hose from the unit and dispose of the 2 copper brake hose gaskets. Secure 2 fresh copper gaskets to the brake hose and fasten it with the brake hose bolt. Affix the brake hose to the caliper bolt along with its 2 new washers while working the bolt to 40nm tension (30ftlbs torque). Place the brake hose correctly into the bracket and fasten it with the retaining clip. Connect the brake hose fitting end to the brake pipe fitting nut using a back up wrench and tighten it to 25 nm torque without bending the bracket or pipe. Drain hydraulic brake fluid and place the tire wheels on then verify suspension parts do not hit the hose during vehicle descent. If contact exists remove the hose after solving the problem.

Ensure a clearance of 19 mm (3/4 inch) from all moving or vibrating components.

Bleed the hydraulic brake system, reinstall the tire and wheel assembly, check that the hose does not contact any suspension or wheel parts during extreme turns, and lower the vehicle.

Remove the brake hose retaining clip and the brake hose from the mounting bracket, followed by the brake hose to caliper bolt from the brake caliper, and then remove the brake hose from the caliper.

Clean all dirt and foreign material from them.

Tighten the fitting to 25 Nm (18 ft. lbs.).

Bend the new brake pipe for a proper fit, then install it while ensuring a clearance of 19 mm (3/4 inch) from all moving or vibrating components.

Always use double-walled steel brake pipe to prevent brake system failure.

Use a backup wrench on the hose fitting to disconnect the brake pipe fitting from the brake hose, then cap or plug the brake pipe fitting end.

Bleed the hydraulic brake system and inspect the brake pipe flares for leaks while the engine is running and brakes are applied.

First raise and support the vehicle, then remove the tire and wheel assembly.

Ensure a clearance of 19 mm (3/4 inch) from all moving or vibrating components.

Use a backup wrench on the hose fitting to disconnect the brake pipe fitting from the brake hose, then cap the fitting end.

Ensure the hose is not twisted and does not contact any suspension component, then install the brake hose into the bracket with the vehicle's weight on the suspension.

First, raise and support the vehicle, then remove the tire and wheel assembly.

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