With ABS

1. Clamp the master cylinder in a vise.






2. Attach Master Cylinder Bleed Tube, Special Tool 8358-1, to the primary port of the master cylinder and tighten in place. Attach Master Cylinder Bleed Tube, Special Tool 8358-2, to the secondary port of the master cylinder and tighten in place. Position the other end of the tubes into the master cylinder reservoir so their outlets are below the surface of the brake fluid in the reservoir when filled.
3. Fill the brake fluid reservoir with Mopar brake fluid, or an equivalent conforming to DOT 3 specifications.
4. Using a wooden dowel as a pushrod , press the pistons inward slowly applying brake pressure, then release the pressure, allowing the pistons to return to the released position. Repeat this several times until all air bubbles are expelled out of the tubes and master cylinder bore.
5. Remove the bleed tubes from the master cylinder and plug the outlet ports.
6. Install the fill cap on the reservoir.
7. Remove the master cylinder from the vise.

NOTE: It is not necessary to bleed the entire hydraulic system after replacing just the master cylinder unless the brake system has been open to air for an excessive amount of time or air is present in the lines. Only the master cylinder must be bled and filled.
