  Q: How to inspect and replace rubber hoses connecting steel brake lines to front and rear brake assemblies?

  A: Inspect rubber hoses every six months with the vehicle raised and supported on jack stands. Look for cracks, chafing, leaks, blisters, or damage. Use light and a mirror for a thorough check. Replace the hose if any issues are found. To replace the front brake hose, loosen lug nuts, raise the vehicle, support on jack stands, and remove the wheel. Unscrew the brake line fitting from a hose at the frame bracket using a flare-nut wrench. Remove the U-clip from the female fitting at a bracket and pass the hose through the bracket. Remove the banjo fitting bolt at the caliper end and separate hose from the Brake Caliper. Check copper sealing washers and replace them if needed. Remove the U-clip from the strut bracket and feed the hose through the bracket. To install the hose, pass the caliper fitting end through the strut bracket, and connect to the caliper using a banjo bolt and copper washers. Ensure locating lug is engaged with a hole in the caliper, and tighten the bolt to the specified torque. Push metal support into strut bracket, install U-clip, ensuring hose is not twisted. Route hose into frame bracket, ensuring it is not twisted, and connect brake line fitting. Install clip and E-ring if provided, and tighten fitting securely. Bleed caliper, install wheel and lug nuts, lowered vehicle, and tighten lug nuts to proper torque. When replacing the rear brake hose, ensure the wheel cylinder is bled properly. Use correct parts for metal brake lines, and avoid copper tubing. Purchase genuine steel brake lines with prefabricated ends and fittings. Securely support new line in brackets, and ensure clearance from moving or hot components. Check the master cylinder fluid level, add fluid if necessary. Bleed brake system and test brakes carefully before driving in traffic.
