Quick Guide to Common Brake Parts

Brake Discs, Pads & Calipers

In a disc brake system, the caliper squeezes the brake pads against the spinning rotor to slow the vehicle.

When to Replace: high-pitched squealing, grinding noises, pedal vibration, or reduced stopping power. A faulty caliper may cause the vehicle to pull to one side when braking, uneven pad wear, fluid leaks, or a dragging sensation with a burning smell.

Brake Master Cylinder

This is the heart of your hydraulic brake system. It converts the force from your foot on the pedal into hydraulic pressure, sending fluid through the lines to activate the calipers.

When to Replace: The brake pedal feels soft, "spongy," or slowly sinks to the floor when you hold it down. This indicates the system can't hold pressure, and it's often time to replace it.

Brake Shoe

In a drum brake system, a wheel cylinder pushes the brake shoe outward, pressing its friction lining against the inside surface of a spinning drum to slow the vehicle.

When to Replace: You hear a scraping sound from the wheels, the parking brake fails to hold the vehicle securely, or you feel a pulsation in the brake pedal when pressing it.
