If not cleaned, dirt The fluid fill level is indicated on the side of the master cylinder reservoir (Fig. 9). The correct fluid level is to the FULL indicator on the side of the reservoir. If necessary, add fluid to the MASTER CYLINDER BLEEDING A new master cylinder should be bled before instal- lation on the vehicle. Required bleeding tools include BLEEDING PROCEDURE (1) Mount master cylinder in vise. Then position each tube end into the reservoir (Fig. (3) Fill reservoir with fresh brake fluid. (4) Press cylinder pistons inward with wood dowel. Then release pistons and allow them to return under BASE BRAKE BLEEDING Use Mopar brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards Do not pump the brake pedal at any time while bleeding. Air in the system will be compressed into Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow Bleed only one brake component at a time in the following sequence: • Master Cylinder • Combination Valve • Rear Antilock Valve • Right Rear Wheel • Left Rear Wheel • Right Front Wheel • Left Front Wheel MANUAL BLEEDING (1) Remove reservoir filler caps and fill reservoir. open all caliper and wheel cylinder bleed screws.
