The brake warning light indicates a potential issue with the brake system, such as low fluid level or brake pad wear.

The ABS modulates brake pressure to prevent wheel lockup, improving steering control and stopping distance.

Machining rotors removes imperfections, restores a smooth surface, and ensures parallelism, reducing brake noise and vibration.

Brake fade occurs when brake fluid overheats, leading to reduced braking efficiency and increased stopping distances.

The type of brake typically used in emergency or parking situations is the hand brake, also known as the parking brake or emergency brake. It is a separate braking system from the primary hydraulic braking system (which may include disc brakes or drum brakes). The hand brake is manually operated and is primarily used to secure the vehicle in a stationary position, especially when parking on slopes or during emergency situations.

system is the master cylinder. The master cylinder is a critical part of the hydraulic braking system. When you press the brake pedal, it creates hydraulic pressure in the master cylinder, which is then transmitted through the brake lines to the brake calipers (in disc brake systems) or wheel cylinders (in drum brake systems).

The purpose of a brake caliper is to engage brake pads. Brake calipers are a crucial component of the braking system in many vehicles. They house the brake pads and, when activated, apply pressure to the brake pads, causing them to make contact with the brake rotor (in disc brake systems) or the brake drum (in drum brake systems).

The brake rotor, when clamped by the brake pads, generates friction that converts kinetic energy into heat, slowing down the vehicle.

DOT-4 brake fluid is commonly used in modern vehicles due to its higher boiling point and compatibility with various brake systems.

The brake fluid reservoir collects excess brake fluid and compensates for fluid displacement as the brake pads wear down.
