Flex Hose, Rear

To change the rear brake hose open your vehicle and first remove its left front wheel assembly. Cleaning both brake hose and pipe components removes debris and foreign objects before capping the outlet with a rubber plug. Hook a flat tool under the brake hose retainer and remove it from the brake hose crossover pipe connection. Eject the brake hose from its frame placement and the caliper bolt from the brake caliper before taking the brake hose out of the vehicle. Strike the threaded brake hose end onto a towel to remove the gasket and discard the 2 stuck copper gaskets from the brake caliper or brake hose end. Insert a rubber plug into the brake caliper bolt hole of the brake caliper. Install new copper gaskets when joining the brake hose to caliper bolt socket. Connect the brake hose, new copper brake hose gaskets, and brake hose bolt together on the brake hose before installing the brake hose to caliper bolt on the brake caliper. Tighten the bolt to 50 n.m (37 lb ft) without twisting or kinking the brake hose. Fit the brake hose on the frame structure before placing the brake hose retainer on the brake hose and taking off the rubber cover from the crossover pipe end. Then insert and tighten the brake pipe fitting onto the brake hose to 18 n.m torque. To complete the process drain the brake fluid from the system then put back the rear wheel parts and lower the car.

Connect them to the intermediate brake hose assembly.

Cut the brake pipe squarely using the pipe cutter included in the J 45405.

Bleed the clutch hydraulic system and reposition the coolant surge tank, securing it with the surge tank bolts.

14 Nm (124 inch lbs.).

Install a rubber cap or plug on the exposed brake pipe fitting end.

Secure the brake pipe to the retainers if previously released, bleed the hydraulic brake system, and inspect for leaks while applying the brakes.

Ensure that the coolant does not need to be drained or the coolant lines disconnected from the coolant surge tank; instead, remove the surge tank bolts and position the tank out of the way.

For installation, attach the clutch hydraulic hose retaining clip to the clutch slave cylinder, ensuring the hose is routed upward above the clutch slave cylinder without sharp bends, kinks, or downward loops, and that it does not contact any sharp or hot surfaces.

Remove the surge tank bolts and position the coolant surge tank out of the way without draining the coolant or disconnecting the coolant lines.

Remove the clutch hydraulic hose retaining clip from the clutch master cylinder and install a cap or plug to the exposed hose and clutch master cylinder fittings to prevent fluid loss and contamination.

Tighten to 50 Nm (37 ft. lbs.).

Connect them to the intermediate brake hose assembly.

Tighten it to 50 Nm (37 ft. lbs.) and ensure the brake hose is not twisted or kinked.

Clean any dirt from the brake hose and brake pipe fittings.

Remove the retainers from the brake hose bracket.

Cut the brake pipe squarely using the pipe cutter included in the J 45405.

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

Insert the prepared end of the pipe into the dies, tighten the clamping screw, and use the forming mandrel to create the flare.

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

Reattach the wheel speed sensor wiring harness retainers, bleed the hydraulic brake system, reinstall the tire and wheel assembly, and lower the vehicle.

Discard the 2 copper brake hose gaskets that may be stuck to the brake caliper or the brake hose end.

Double-walled steel brake pipe.

Remove the brake hose to caliper bolt from the brake caliper and take the brake hose out of the vehicle.
