Front & Rear Split Hydraulic Brake Systems

When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective independent hydraulic systems. The fluid displacement of the two master cylinders is proportioned to fulfill the requirements of each of the two independent hydraulic brake systems, Fig. .

If a failure of a rear (secondary) brake system should occur, initial brake pedal movement causes the unrestricted secondary piston to bottom in the master cyl...

Brake System Bleed

The BENDIX ABX-4 anti-lock brake system must be bled as two independent braking systems. The non ABS portion of the brake system should be bled the same as any non ABS system. The ABS portion of the system requires the use of a DRB or equivalent scan tool.

• To bleed the non ABS portion of the system using a pressure bleeder, proceed as follows:
• Connect pressure bleeder tool No. C-3496-B, or equivalent, and adapter BB400-9A or equivalent to pressurize brake system. Follow manufactures instructions, for use of pressure bleeding equipment.
• Attach clear hose to bleeder ...

Type 2 Master Cylinder

Brake Booster Pushrod-To-Primary Piston Clearance

• With master cylinder removed from vehicle, as described under "Component Replacement," proceed as follows:
• Measure distance between master cylinder end face and the piston, Fig. . Position a square (straight scale) against edge of master cylinder, then measure and subtract thickness of the square to determine dimension B.
• Find dimension C by measuring distance between brake booster mounting surface and the end face, Fig. .
• Measure distance between master cylinder mounting surface and the pushrod end, Fig. . Find dimen...

Decreasing Brake Pedal Travel

If a decreasing brake pedal is encountered, the power brake unit may be binding internally. To test the power brake unit for this condition proceed as follows:

• Place transmission shift lever into Neutral and start engine.
• Increase engine speed to approximately 1500 RPM, close throttle and completely depress brake pedal.
• Slowly release brake pedal and stop engine.
• Remove vacuum check valve and hose from power brake unit. Observe for backward movement of brake pedal.
• If brake pedal moves backward, power brake unit has internal binding. Replace power brake u...

Accessing Diagnostic Trouble Codes

A DRB or equivalent scan tool is necessary to access the ABS diagnostic trouble codes. Connect the scan tool to the Data Link Connector (DLC) located under the lefthand side of the instrument panel, Figs. and . The diagnostic cycle begins when the ignition key is turned to the ON position. Refer to "Test 1A" for DRB readout and appropriate test number.

Diagnostic Trouble Code Interpretation

There are two types of diagnostic trouble codes that can be set: "Latching" and "Non-Latching." A latching code will turn on the ABS warning lamp and disable th...

Bleeding the hydraulic brake system is necessary if air has entered the system. A few causes for this condition are low fluid level, a hydraulic fluid leak, a hydraulic line is opened, or replacement of a hydraulic system component. Symptoms can be noted by an improper or loss of brake operation, and/or a low or spongy brake pedal.

Flushing the hydraulic brake system is necessary if contaminants are found in the hydraulic system. A few causes for hydraulic system contamination are moisture, age of hydraulic system parts and fluid, or improper fluid used in the system. Symptoms...
