Note: To bleed hydraulic circuits of the Bendix Antilock 4 Brake System modulator assembly, the aid of a second mechanic or helper will be
required to pump the brake pedal.

container partially filled with fresh clean brake fluid (Fig. 1).
2. Pump brake pedal several times, then apply and hold a constant medium to heavy force on brake pedal.
3. Open primary check valve circuit bleed screw (Fig. 1) at least 1 full turn to ensure an adequate flow of brake fluid. Continue bleeding
primary check valve circuit until brake pedal bottoms.
4. After brake pedal bottoms, close and tighten bleed screw. Then release brake pedal. Do not release brake pedal prior to closing and
tightening bleed screw.
5. Continue bleeding modulator assembly, repeating steps 2 through 4 until a clear, bubble free flow of brake fluid is evident.
6. When all air is bled from primary check valve circuit, tighten bleed screw and remove bleed hose from bleed screw. Do not remove
bleed hose before tightening bleed screw, air may re-enter modulator.
