  2.  
  3. If necessary, remove the wheel for easier access to the hose.
  4.  
  5. Disconnect the hose from the wheel cylinder or caliper and plug the opening to avoid excessive fluid loss or contamination.

To install:
  1. Connect the brake hose to the brake line and tighten to 14 ft. lbs. (19 Nm) for rear brakes or 18 ft. lbs. (24 Nm) for front brakes.
  2.  
  3. If installing a front brake hose, make sure the hose is routed as shown in the graphic, with the loop to the rear of the vehicle.
  4.

Brake Line

There are 2 options available when replacing a brake line. The first, and probably most preferable, is to replace the entire line using a line of similar length which is already equipped with machined flared ends. Such lines are usually available from auto parts stores and usually require only a minimum of bending in order to properly fit then to the vehicle. The second option is to bend and flare the entire replacement line (or a repair section of line) using the appropriate tools.

Buying a line with machined flares is usually preferable because of the time and effort saved, not to mention the cost of special tools if they are not readily available. Also, machined flares are usually of a much higher quality than those produced by hand flaring tools or kits.

  1. Raise the end of the vehicle which contains the hose to be repaired, then support the vehicle safely using jackstands.
  2.  
  3. Remove the components necessary for access to the brake line which is being replaced.
  4.  
  5. Disconnect the fittings at each end of the line, then plug the openings to prevent excessive fluid loss or contamination.
  6.  
  7. Trace the line from one end to the other and disconnect the line from any retaining clips, then remove the line from the vehicle.
  8.  

To install:
  1. Try to obtain a replacement line that is the same length as the line that was removed. If the line is longer, you will have to cut it and flare the end, or if you have decided to repair a portion of the line, see the procedure on brake line flaring, later in this section.
  2.  
  3. Use a suitable tubing bender to make the necessary bends in the line. Work slowly and carefully; try to make the bends look as close as possible to those on the line being replaced.
  4.  

When bending the brake line, be careful not to kink or crack the line. If the brake line becomes kinked or cracked, it must be replaced.

  1. Before installing the brake line, flush it with brake cleaner to remove any dirt or foreign material.
  2.  
  3. Install the line into the vehicle. Be sure to attach the line to the retaining clips, as necessary. Make sure the replacement brake line does not contact any com
