Front Passenger Brake Tube Inspection


  1. Open the hood and place a protective cover over the RH fender.


  1. Locate the ABS actuator on the passenger side of the vehicle.


  1. Using a mirror, inspect the entire length of the under-hood portion of the front passenger brake tube for pinches, gouges, scrapes, or abrasions around the entire circumference of the brake tube.
  • If NO pinches, gouges, scrapes, or abrasions are found on the brake tube, no further action is needed. Skip to CLAIMS INFORMATION on last page.
  • If the brake tube has any pinches, gouges, scrapes, or abrasions, continue to step 4 for front passenger brake tube replacement.


  1. Place the vehicle on a suitable lift.


Front Passenger Brake Tube Replacement


To avoid the risk of death or severe personal injury:


  • Do not allow the reservoir tank to empty, as this may cause damage to the master cylinder internal components or the brake system.


  • Do not allow foreign matter (e.g. dust and oils other than brake fluid) to enter the ABS Actuator or Master Cylinder reservoir tank.



To avoid damage to the vehicle:


  • Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface.




  • All hoses and piping (tubes) must be free from excessive bending, twisting, and pulling.


  • Make sure there is no interference with other parts when turning steering both clockwise and counterclockwise.


  1. Disengage the upper brake tube retainer.


  1. Disengage the lower brake tube retainer.


  1. Using a flare nut wrench, loosen and separate the front passenger brake tube flare nut from the ABS actuator.


  1. Lift the vehicle to a suitable height, and then remove the front passenger wheel and tire assembly.


  1. Using a flare nut wrench, loosen and separate the brake tube flare nut from the brake hose.


  1. Carefully disengage the front passenger brake tube from the brake tube retainer.


  1. Lower the brake tube down, toward the rear of the front passenger drive shaft assembly, as shown in Figure 8.


  1. Lower the vehicle down enough to allow access to both ends of the front passenger brake tube.


  1. Move the under hood end of the front passenger brake tube away from the ABS actuator and route under the A/C line.


  1. Remove the front passenger brake tube from the vehicle wheel well, as shown in Figure 10.
