Flex Hose

Begin by lifting the vehicle for inspection of the retaining clip before starting your work. Replace this component immediately when you find it flattened or damaged. Detach the retaining clip from the mounting bracket while you use a back up wrench to disconnect the Brake Line from the brake hose. Reduce fluid loss and minimize contamination by putting on a rubber cap or plug at the exposed brake pipe fitting. You need to unhook both Wheel Cylinder brake lines before capping them off. Extract the brake mounting bolt and then extract the rear brake hose from its location. One should install the rear brake hose retaining clip after tightening the Brake Line mounting bolt to 17 nm (13 lb ft). Install the rear brake hose onto the mounting bracket and start the mounting bolt installation while remembering to rotate the bolt by hand first before completing the full tightening. Tighten the connection of the left brake hose to its Brake Line fitting while using a torque wrench to reach 19 nm (14 lb ft). Close off the right Brake Line and top off the master cylinder reservoir (if needed). Bleed the brake system as the final step while simultaneously lowering the vehicle.

You should inspect the rear brake hose retaining clip when raising the vehicle to see if it needs replacement due to flattening or damage. Using a back up wrench securely detach the Brake Line from the brake hose while simultaneously capping the exposed brake pipe fitting with rubber plug or cap to minimize fluid-loss and protect against contamination. Begin replacement by covering the Brake Line followed by disconnecting the left and right Wheel Cylinder lines then removing the mounting bolt for the brake hose to remove the rear brake hose. First tighten the mounting bolt to the brake hose or brake lines by hand until specification before securing it at 17 nm (13 lb ft). Then install the Brake Line onto the brake hose before proceeding with the mounting bolt tightening process. Fasten the newly installed retaining clip on the rear brake hose mount while also attaching the mount bolt for assembly. Open the rubber plug from the left Brake Line and join it to the brake hose and torque up the fitting to 19 nm (14 lb ft). Bleed the brake system after filling the master cylinder reservoir if needed and repeat the process for the right Brake Line. After that complete the brake system bleed procedure and lower the vehicle.

Inspect the brake pipe flares for leaks while the engine is running and brakes are applied.

Inspect the flare for correct shape and diameter.

Tighten it to 17 Nm (13 lb ft).

Remove the copper gaskets from the brake hose bolt, as these may stick to the brake caliper or bolt.
