Study Notes
Tire Traction
- Maximum tire traction occurs when slipping is between 10 to 20 percent.
Antilock Brake Systems (ABS)
- ABS cannot overcome physics in the following situations:
- Entering a corner too fast.
- Brakes applied too late to prevent impact.
- Ineffective in stopping quickly under all conditions.
- ABS may not provide shorter stopping distances compared to traditional brakes.
- Pulsating brake pedal during normal braking is common in ABS-equipped vehicles.
ABS Types and Sensors
- The antilock brake system requiring four wheel speed sensors is a four-channel system.
- Some ABS setups utilize a rear axle pinion gear area sensor, while not all systems have a sensor at each wheel.
Technician Insights on ABS
- Most ABS units are classified as non-integral systems.
- ABS functionality is typically disabled below about 5 mph.
Steering and Indicators
- ABS allows steering control during heavy braking.
- The ABS dashboard warning light is amber in color.
Wheel Speed Sensors
- A passive wheel speed sensor is also known as a variable reluctance sensor.
- Active wheel speed sensors can be classified as either Hall effect or magneto resistive types.
Tire Pressure Monitoring
- Wheel speed sensors play a key role in tire pressure monitoring within an antilock brake system.
