Flex Hose, Rear Driver Side

To replace rear (Caliper) brake hose, raise and support vehicle and tire and wheel assembly. Clean all dirt and foreign matter from brake hose end and brake pipe fitting, and attach a rubber cover or plug on brake fitting end to the exposed brake pipe to prevent brake fluid from losing and contaminating there. Use a back up wrench on the brake hose end to remove the brake pipe end from brake hose and cap/plug the brake pipe end. Take out the brake hose from the bracket, remove brake hose retaining clip from the mounting bracket. Next will be the unpicking of the brake hose caliper bolt from the brake caliper and discarding the 2 copper brake hose gaskets which could be stuck to the brake caliper housing or the brake hose end. For installation, also install 2 new copper brake hose gaskets and the brake hose bolt to the brake hose, then install the brake hose to caliper bolt and 2 new washers to the brake caliper, tightening the bolt to 40 nm (30 ft. Lbs.) and make sure brake hose is not twisted or in contact with any suspension component. Mount the brake hose into the mounting bracket and secure with brake hose retaining clip. Take off the rubber cap or plug from the exposed brake pipe fitting end and join the brake pipe fitting end with the brake hose end using a back up wrench in the brake hose part end without bending the mounting bracket or the brake pipe while tightening the brake hose fitting end end at 25 nm (18 ft. Lbs.). Bleed the hydraulic brake system and reinstall the tire and wheel assembly getting the brake house free from touching parts of the suspension and the tire/wheel assembly. If it does so, then it is necessary to remove the brake hose and fix the condition before lowering the vehicle.

During the process of replacing the rear jounce brake hose, first, lift and support the vehicle. Clean all dirt, grease or foreign material from the hose fittings, and then detach the jounce hose from the brake pipe to the frame. Unscrew the jounce hose retaining clip and proceed to remove the jounce hose from the bracket. Next, remove the left and right brake pipes from the junction block of the jounce hose, and then remove the junction block mounting bolt from axle until the jounce hose comes out completely. For installation, place the jounce hose without twisting it, fasten to the axle the jounce hose junction block mounting bolt, tightening to 12 nm (106 in. Lbs.). Connect the brake pipes from both sides to the jounce hose junction block, with fitting done tight at 25 nm (18 ft. Lbs.). You must reinstall the jounce hose onto the bracket and secure it to the bracket with retaining clip and connect it at the frame into the brake pipe by locking the fitting to 25 nm(18 ft. Lbs.). Lastly, bleed the brake system, and take off the safety stands and put the vehicle down.

Assemble 2 new copper brake hose gaskets and the brake hose bolt to the brake hose, then install the brake hose to caliper bolt and 2 new washers to the brake caliper, tightening the bolt to 40 N.m (30 lb ft) while ensuring the brake hose is not twisted or in contact with any suspension component.

The pipe cutter from the J 45405.

Bleed the hydraulic brake system, then install the tire and wheel assembly, ensuring the brake hose does not contact any part of the suspension or tire/wheel assembly, and inspect the brake hose during extreme right and left turns.

Remove the brake hose retaining clip from the brake hose mounting bracket, the brake hose bracket bolt from the upper control arm and steering knuckle, and the brake hose to caliper bolt from the brake caliper.

Bleed the hydraulic brake system.

Remove the caps or plugs from the rear brake pipes and connect them to the junction block on the axle, tightening the fitting to 25 Nm (18 ft. lbs.).

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

Shape the new pipe if necessary, install it to the vehicle with the appropriate unions, secure it to the retainers, bleed the hydraulic brake system, and inspect the brake pipe flares for leaks while the engine is running and brakes are applied.

Discard the 2 copper brake hose gaskets when removing the brake hose.

Remove the brake hose mounting bolt and compression washers, then take out the brake hose, discarding the washers.

Install the jounce hose retaining clip.

Remove the rubber cap or plug from the brake pipe fitting end and connect it to the brake hose using a backup wrench, ensuring not to bend the mounting bracket or brake pipe, and tighten the brake pipe fitting end to 25 Nm (18 ft. lbs.).

Disconnect the jounce hose from the brake pipe at the frame, remove the jounce hose retaining clip, and take the jounce hose out of the bracket.

Disconnect the brake pipe fittings and remove the brake pipe fasteners from the vehicle.

Remove the caps or plugs from the rear brake pipes and connect them to the jounce hoses, tightening the brake pipe fittings to 25 Nm (18 ft. lbs.).

Remove the brake hose retaining clip, the brake hose bolt from the axle, and the brake hose mounting bolt along with the compression washers at the caliper.

Remove the brake hose retaining clip from the mounting bracket, the brake hose bracket bolts from the upper control arm and steering knuckle, and the brake hose to caliper bolt from the brake caliper.

Maintain a clearance of 6 mm (0.25 inch) between brake pipes that run parallel to each other.

Install the rear brake hose and then attach the junction block retaining bolt to the axle, tightening it to 12 Nm (106 inch lbs.).

Install the brake hose bolt and bracket to the steering knuckle and upper control arm, tightening both bolts to 9 Nm (80 inch lbs.), and then install the brake hose retaining clip.

Clean all dirt from the brake hose and brake pipe fittings, and install a rubber cap or plug on the exposed brake pipe fitting ends to prevent fluid loss and contamination.

Cap or plug the brake pipe fitting end.

Bend the new brake pipe for a proper fit.

Raise and support the vehicle, then remove the tire and wheel assembly.
