Flex Hose

Before replacing the front brake hose you need to drain brake fluid from the master cylinder reservoir. Lift the car and take off its front tire and wheel unit. Before disconnecting the front brake hose from the pipe environment you must clean up dirt buildup at both ends. First disconnect the top and bottom hose clips then the front brake hose from the front strut before removing the brake caliper hose bolt and seal washers together with the brake hose. Insert the brake hose through the brake caliper alongside both seal washers and bolt them tightly with a 23 nm torque (17 ft. Lbs.). Fit the brake lines into their positions on the front strut and hang both hose clips in place before linking the front brake hose with the front brake pipe. Begin bleeding the brake system before you put back the front tire wheel set and lower the vehicle.

First install the hydraulic pipe, ensuring to follow the Fastener Notice in Service Precautions.

Use the two wrenches (3, 4) to install the flare nuts, tightening them to 16 Nm (12 ft. lbs.).

Install the E-clip that connects the hoses and pipes.

Raise and support the vehicle, ensuring it is secure.

Take out the hydraulic hose and inspect it for any dents, kinks, cracks, dirt, or dust, and replace it if necessary.

Inspect the hoses for any dents, kinks, cracks, or dirt, and replace if necessary.
