Approximately, every half a year, with the vehicle off the ground and supported on jackstands, check the flexible rubber hoses which connect steel brake lines to the front and the rear brake assemblies as they are the vital part of the braking system of a vehicle and may be damaged due to the cracks, chafing, leaks, blisters, and others. A light and mirror should be used for this purpose and any damaged hoses should be replaced with new ones. Before replacing a brake hose, one is required to remove the wheel by loosing the wheel lug nuts, lifting the vehicle. And using the flare-nut wrench to unscrew the brake line fitting from the hose without rounding the corner. One has to unscrew the female fitting at the bracket by using the pair of pliers and immerse the hose through it. At the caliper end, unbolt the banjo bolt and disconnect the hose from the caliper; in this process, be sure to slot in the two sealing washers before reconnecting. For front brake hose replacement, disconnect the hose from the strut bracket, and push the caliper hose end through the new hole in the strut bracket, and tighten the banjo bolt coupled with a new sealing washer in the caliper hose while making sure not to twist the new hose. Push the hose into the frame bracket, use only hand to screw the brake line fitting in place, then put the U-clip on it and tighten the hose line fitting. Then, bleed the caliper, fit the wheel back on and screw the lug nuts on, then lift the car, and torque the lug nuts to the required tightness. Specifically for replacement of brake lines, correct steel parts should be used and copper tubing should not be used. Flared brake tube with inserted fittings can be bought in auto part stores with brake lines matched ready to be installed. Guarantee the new line has good mechanical support on the brackets and is sufficiently guarded from hot or moving parts. If you installed your brake system recently then after installation you should check master cylinder fluid level and if it is low then add fluid in the master cylinder; then release the brake system's air before a test drive in traffic.
