TM 10-3930-671-24 Table 2-2.  Unit Troubleshooting Procedures - CONT: MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION INCHING BRAKE SYSTEM (CONT.) 26. INCHING BRAKE PEDAL SPONGY - CONT. Step 2. Check for air in brake system (Appendix F, Brakes, Section 8.0). If air is in brake system, bleed brake system (Appendix F, Brake Bleeding, Section 8.5). If no air is in brake system, go to step 3. Step 3. Cap inching cylinder exit port and check inching brake pedal firmness. If inching brake pedal is not firm, replace brake master cylinder (Para 3-29). If inching brake pedal is firm, notify DS/GS maintenance. STEERING SYSTEM 27. NO STEERING. Step 1. Check power steering system for faulty hoses (Para 3-30). If one or more hoses is faulty, replace hoses (Para 3-30). If hoses are not faulty, go to step 2. Step 2. Check hydraulic pump output pressure (Appendix F, Hydraulic Sump - Fluid and Filter Change, Section 10.1). If hydraulic pump pressure is below 2500 psi (17237 kPa), replace hydraulic pump. Notify DS/GS maintenance. If hydraulic pump pressure is 2500 psi (17237 kPa), go to step 3. Step 3. Check hydraulic fluid system for air leaks (Appendix F, Hydraulic System Relief Pressure Check & Adjustment, Section 10.2). If air leaks are present, secure connections. If air leaks are not present, faulty steering valve.  Notify DS/GS maintenance. 2-17
