As needed when the vehicle is up on jackstands every six months, check the rubber parts connecting steel brake tubing to your front and rear brake parts for breaks, scuffs, leaks, bumps, and other harm. If any hose shows these conditions, replace it. When changing flexible front brake lines, first loosen the wheel lug nuts, lift the car off the ground, and take off its wheel. Use a flare-nut wrench to loosen the brake hose bracket's connection from the frame fitting. Then take out the brake hose bracket from its position on the steering knuckle. Take off the U-clip from the female fitting on the bracket, and insert the hose through. Take off the bolt from the caliper end that holds the inlet fitting, disconnect the hose from the caliper, and throw away the copper sealing washers. Hold the new caliper inlet fitting to the caliper securely, add its bolt with new sealing washers, then tighten it correctly. Insert the hose into the bracket on the frame, keep it straight,matches the fittings together, and attach the U-clip, then tighten all connections. First, take care of the bleeding in the caliper; put the wheel and nuts on, put the vehicle in a lowered position, and finish by tightening all lug nuts to their proper torque level. To fix a rear brake hose, lift your car, block its front wheels, take off the brake line fitting from the hose by unscrewing it with a flare-nut wrench where it meets the chassis bracket, then remove the U-clip from the female fitting on the bracket. When dealing with the Armada brake setup, unwind the inlet fitting bolt and pull the fitting off the caliper, keeping the sealing washers. Always use correct steel brake parts and never use copper to refresh your brake lines. You can buy prefabricated brake lines that come with flared ends and installed fittings, but you need to use a lubing bender to shape them into the right angles. Keep the new tube anchored tightly in the brackets so it stays away from moving or hot parts. First check and fill up the master cylinder fluid, and then pressurize the brake system to remove air (bleed), before taking your vehicle out for a test run.
