ANTI-LOCK BRAKE SAFETY PRECAUTIONS 1991 Mitsubishi Montero GENERAL INFORMATION Anti-Lock Brake Safety Precautions * PLEASE READ THIS FIRST * This article is intended for general information purposes only. This information may not apply to all makes and models. If vehicle is equipped with Anti-Lock Brake System (ABS), refer to appropriate ANTI-LOCK BRAKE SYSTEM article in the BRAKES section for description, operation, depressurizing, testing, system bleeding, trouble shooting and servicing of specific system. WARNING: Failure to depressurize ABS could lead to physical injury. ANTI-LOCK BRAKE SAFETY PRECAUTIONS WARNING: Failure to depressurize ABS could lead to physical injury. * NEVER open a bleeder valve or loosen a hydraulic line while ABS is pressurized. * NEVER disconnect or reconnect any electrical connectors while ignition is on. Damage to ABS control unit may result. * DO NOT attempt to bleed hyudarulic system without first referring to the appropriate ANTI-LOCK BRAKE SYSTEM article in the BRAKES section. * Only use specially designed brake hoses/lines on ABS equipped vehicles. * DO NOT tap on speed sensor components (sensor, sensor rings). Sensor rings must be pressed into hubs, NOT hammered into hubs. Striking these components can cause demagnetization or a loss of polarization, affecting the accuracy of the speed signal returning to the ABS control unit. * DO NOT mix tire sizes. Increasing the width, as long as tires remain close to the original diameter, is acceptable. Rolling diameter must be identical for all 4 tires. Some manufacturers recommend tires of the same brand, style and type. Failure to follow this precaution may cause inaccurate wheel speed readings. * DO NOT contaminate speed sensor components with grease. Only use recommended coating, when system calls for an anti-corrosion coating. * When speed sensor components have been removed, ALWAYS check sensor-to-ring air gaps when applicable. These specifications can be found in each appropriate article. * ONLY use rocommended brake fluids. DO NOT use silicone brake fluids in an ABS equipped vehicle. * When instlling transmittion devices (CB’s, telephones, etc.) on ABS equipped vehicles, DO NOT locate the antenna near the ABS control unit (or any control unit). * Disconnect all on-board computers, when using electric welding equipment. * DO NOT expose the ABS control unit to prolonged periods of high heat (185 F/85 C for 2 hours is generally considered a maximum limit). |
