Explain how a suspension supports the vehicle, provides a smooth ride, promotes rapid economy, keeps tires firmly on the ground, prevents excessive body movement, and enables turning freely.

Compare the McPherson strut, a compact, low-cost suspension used in most vehicles. Explain how the double wishbone offers better control with two arms and a separate damper and spring.

Explore the four components of a suspension system—the wheel assembly, linkages, springs, and dampers—and how they maintain directionality, return the wheel assembly to its natural condition, and dampen oscillations.

Learn caster angle relative to the vertical, positive caster tilting rearward and negative toward the front, camber tilt top inward versus outward, and toe alignment affecting the contact patch.

Explain camber gain during wheel motion, from negative camber to positive camber in corners, and its effect on the tyre contact patch and grip; discuss the cornering–braking tradeoff.

Explore anti dive and anti squat by locating the instantaneous center relative to the vehicle’s center of gravity. See how suspension geometry controls vertical loads and weight transfer.

Explore how brake rotors are ventilated and drilled to evacuate water vapor between pads and discs, preventing latent frost and sustaining braking performance across straight, pillar-type, and turntable designs.

The air compressor pumps air into a storage tank, with the air dryer removing moisture; the brake pedal uses a triple valve to transfer pad-drum friction to stop the vehicle.

Learn how the combination valve, housing metering and proportioning valves, delays front brake activation in rear-drum systems and uses a warning switch and shuttle valve to manage pressure loss.

Discover how residual valves maintain brake line pressure after pedal release, keeping brake fluid pressure in the brake cylinders and preventing air from entering the system.

Demonstrates line lock operation as a physical valve controlling front brake pressure while allowing rear brakes to release, heating tires for increased grip before a race.

Explore how tire performance hinges on rubber chemistry and reinforced construction, balancing natural and synthetic rubbers, carbon black fillers, and nylon or kevlar to deliver grip, durability, and load handling.

Explore tyre construction, from the primary layer to rubber-coated steel, fiberglass, and rayon reinforcements, and how tread grooves drain water to boost traction on various surfaces.

Explore tyre force tests to understand how the tyre carcass deforms under loads and inflation pressures, measure slip, and determine the maximum cornering force the tyre can provide.

Learn to service an anti-lock braking system by purging and replacing brake fluid in the abs module, using a manual bleed sequence: left rear, right rear, left front, right front.

Learn how abs dependent systems work with traction control, dynamic stability control, and electronic brake force distribution to maintain control, prevent skidding, and optimize braking on various surfaces.
