Figure 7:

The subject vehicles utilize brake tubes with ISO flares (Figure 6) and metric tube nut(s) at the master cylinder. These brake tubes are installed from the brake master cylinder to the left and right front brake hoses. The fittings at the master cylinder are either M10 or M12 metric 3/16 tube nuts, whereas the fittings at the front brake hoses are standard 3/8-24 3/16" tube nuts, used with a double flare (Figure 7).

If a brake tube replacement is required from the brake master cylinder to the left or right front brake hose, the following procedure must be used:

1. Obtain the recommended bulk 3/16" steel tubing and the correct standard 3/8-24 3/16" tube nut.

NOTE:
The M10-M12 metric nut(s) will be reused.

2. Cut tubing to the length required. Clean burrs after cutting. The correct length may be obtained by measuring the removed tube using a string and adding 1.2 mm (1/8") for each flare.
3. ISO flare one end of the tube using Special Service Brake Line Flaring Tool Part Number D81L-2269-A or equivalent.
4. Place the removed metric tube nut on the tube.
5. On the opposite end of the replacement tube, install a standard 3/8-24 3/16" tube nut and double flare the tube end.

NOTE:
Follow flaring instructions included in the D81L-2269-A Special Service tool kit or equivalent.
6. Bend the replacement brake tube to match the removed tube using a tubing bender. When the replacement brake tube is installed, maintain adequate clearance to all moving or vibrating parts.
