Buick Encore: 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.
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 hydraulic 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 recommended brake fluids. DO NOT use silicone brake fluids in
an ABS equipped vehicle.
When installing transmission 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 ºF/85ºC for 2 hours is
generally considered a maximum limit).
