When performing a brake inspection, what should be checked for corrosion?

The inspection of brake components for corrosion is critical for maintaining effective braking performance and safety. The brake lines, calipers, and the brake master cylinder are significant areas to check because they are vital components of the braking system.

Brake lines are often made of metal and can be susceptible to rust and corrosion, which may cause leaks, potentially leading to brake failure. Calipers, which house the pistons that clamp down on the brake pads, can also corrode, affecting their functionality and leading to uneven brake wear or reduced braking power. The brake master cylinder, responsible for generating hydraulic pressure, can deteriorate if corrosion occurs, leading to inadequate brake response.

In contrast, while brake fluid, tires, and pads are integral to the braking system, corrosion is not typically a concern for them. Brake fluid can absorb moisture, which is a different issue. The tires and pads are wear components that do not corrode in the same way that metallic parts do. Similarly, checking rotors, wheels, and chassis has its importance, but corrosion inspection specifically focuses on the components directly involved in brake operation. Brake sensors, light indicators, and drums are relevant for their functionality but do not face the same corrosion risks as the primary hydraulic components.
