What is the primary purpose of caster camber gauges?

The primary purpose of caster camber gauges is to measure and adjust the angles of camber and caster in wheel alignment. This is critical for ensuring that the vehicle's wheels are correctly aligned, which directly affects handling, tire wear, and overall vehicle stability.

Camber refers to the angle of the wheel relative to the vertical axis when viewed from the front of the vehicle. Proper camber can help enhance tire grip and reduce uneven tire wear. Caster, on the other hand, relates to the angle of the steering axis and can impact the stability of the steering as well as the vehicle’s tracking characteristics.

Using caster camber gauges allows technicians to accurately assess these angles and make necessary adjustments to bring them within manufacturer specifications. This ensures that the vehicle operates effectively, providing safe handling and extending the life of the tires.

The other choices are less relevant to the function of caster camber gauges, as they do not specifically relate to measuring wheel alignment angles. For instance, measuring tire pressure is unrelated, adjusting steering wheel position focuses more on steering components rather than alignment angles, and evaluating brake performance involves a completely different set of tools and measurements.
