Flex Hose, Rear

To replace the rear brake hose, first include raising of the vehicle and removal of the tire and wheel assembly. Clean the brake hose and the brake pipe fittings of all the dirt and foriegn material. With the help of back up wrench, the rear brake hose should be disconnected from the brake pipe hinge to ensure the installation of a rubber plug or a cap on the exposed end of the brake pipe fitting hoses to prevent the chances of losing brake fluids or contamination. Then pull out the Brake Line retainer bolt with the frame, and brake hose bolt from the brake caliper being careful to pull out any metal gaskets bonded to brake caliper or brake hose end and dispose of the copper gaskets. For installing, ensure that it is done with new copper gaskets at the rear brakes' caliper bolt and install the rear brake hose at the rear brakes' caliper and tighten the rear brakes bolt with 44 nm (23ft. Lbs). Unfit the rubber plug or cap of the rear brake pipe fitting, secure the brake pipe to the brake hose, and immobilize the rear brake pipe fitting with the back ups with a torque of 220nm (180ft.lbs.). Mount the brake pipe retaining bolt at the frame and torque it to the value of 20 nm (18 ft. Lbs). Finally, perform a bleed on the hydraulic brake system, install the tire and wheel assembly and bring down the vehicle.

Use a backup wrench to remove the rear brake hose from the brake pipe, and install a rubber plug or cap on the exposed brake pipe fitting ends to prevent brake fluid loss and contamination.

Attach it and tighten the rear brake bolt to 44 N.m (23 lb ft).

Connect the brake pipe to the brake hose, tightening the fitting to 20 Nm (18 ft. lbs.), fill the brake master cylinder reservoir, and bleed the hydraulic brake system.

Fill the brake master cylinder reservoir, bleed the hydraulic brake system, install the front tires and wheels assembly, and finally lower the vehicle.

Remove the rubber cap or plug from the brake pipe fitting and connect the brake pipe to the brake hose, tightening the fitting to 20 Nm (18 ft. lbs.).

Use the pipe cutter included in the J 45405 to cut the brake pipe to the measured length.

Remove the line clip and the hydraulic line from the master cylinder.

Fill the master cylinder with fluid and bleed the hydraulic system.

Use only NEW copper gaskets on the brake hose and bolt.

Tighten the rear brake bolt to 44 Nm (23 ft. lbs.).

Clean all dirt and foreign material from them.

Bleed the hydraulic brake system, reinstall the tire and wheel assembly, and lower the vehicle.

Inspect the shape and diameter of the flare to ensure it meets specifications.

The de-burring tool included in the J 45405.

Tighten the fitting to 17 Nm (13 lb ft).

Proceed to bleed the hydraulic brake system.

Ensure that the metal gaskets are removed from both the brake hose end and the brake caliper, discarding the copper gaskets.

New copper gaskets.

Remove the brake hose bolt from the brake caliper assembly and take out the brake hose from the vehicle, ensuring to remove any metal gaskets stuck to the brake caliper or brake hose end, and discard the copper gaskets.

Clean all dirt and foreign material from them.

Remove the plug or cap from the exposed brake pipe fitting, install the brake hose to the brake pipe, ensuring the hose is not twisted and does not contact any suspension components.

20 Nm (15 ft. lbs.) for the BPMV or wheel jounce hoses, 30 Nm (22 ft. lbs.) for the master cylinder, and 20 Nm (20 ft. lbs.) for the brake hose fitting.

Repeat the process for the right brake line, ensuring to tighten it to the same specification.

Tighten the brake hose bolt to the frame to 20 Nm (15 lb ft).
