Brake pads are a crucial component of a vehicle’s braking system, responsible for converting the kinetic energy of the vehicle into heat energy, thereby slowing or stopping the vehicle. The brake pads are attached to the brake caliper, which is a metal housing that contains the brake pads and other components. In this blog post, we will delve into the details of what brake pads are attached to, exploring the various components and systems involved in the braking process.

Brake Calipers: The Attachment Point of Brake Pads
The brake caliper is a critical component of the braking system, and it serves as the attachment point for the brake pads. The caliper is typically mounted to the wheel hub or the steering knuckle, and it contains the brake pads, pistons, and other components. The caliper is designed to apply pressure to the brake pads, which in turn press against the brake rotor to slow or stop the vehicle.
Types of Brake Calipers
There are several types of brake calipers, each with its own unique characteristics and applications. Some of the most common types of brake calipers include:
- Fixed Calipers: These calipers are attached to the wheel hub or steering knuckle and are typically used on high-performance vehicles.
- Sliding Calipers: These calipers are designed to slide back and forth on the rotor, allowing for more precise control over the braking process.
- Floating Calipers: These calipers are designed to float on the rotor, allowing for more even pressure distribution and improved braking performance.
- Disc Brake Calipers: These calipers are designed specifically for disc brake systems and are typically used on high-performance vehicles.
Brake Caliper Components
The brake caliper contains several key components, including:
- Brake Pads: These are the components that press against the brake rotor to slow or stop the vehicle.
- Pistons: These are the components that apply pressure to the brake pads, causing them to press against the brake rotor.
- Caliper Housing: This is the metal housing that contains the brake pads, pistons, and other components.
- Caliper Bolts: These are the bolts that secure the caliper to the wheel hub or steering knuckle.
Brake Rotor: The Surface that Brake Pads Press Against
The brake rotor is a critical component of the braking system, and it serves as the surface that the brake pads press against to slow or stop the vehicle. The brake rotor is typically made of cast iron or aluminum and is designed to withstand the high temperatures and stresses generated during the braking process.
Types of Brake Rotors

- Drilled Rotors: These rotors have holes drilled into them to improve cooling and reduce brake fade.
- Slotted Rotors: These rotors have slots cut into them to improve cooling and reduce brake fade.
Brake Hoses and Lines: The Connection between the Brake Caliper and the Master Cylinder
The brake hoses and lines are critical components of the braking system, and they serve as the connection between the brake caliper and the master cylinder. The brake hoses and lines are designed to withstand the high pressures and temperatures generated during the braking process. (See Also: When to Get New Brake Pads? Signs Of Wear And Tear)
Types of Brake Hoses and Lines

Brake Fluid: The Hydraulic Fluid that Powers the Braking System
Brake fluid is a critical component of the braking system, and it serves as the hydraulic fluid that powers the braking system. Brake fluid is designed to withstand the high pressures and temperatures generated during the braking process.
Master Cylinder: The Component that Converts Non-Hydraulic Brake Pedal Pressure into Hydraulic Pressure
The master cylinder is a critical component of the braking system, and it serves as the component that converts non-hydraulic brake pedal pressure into hydraulic pressure. The master cylinder is typically mounted to the brake pedal and contains the brake fluid reservoir.
Types of Master Cylinders
There are several types of master cylinders, each with its own unique characteristics and applications. Some of the most common types of master cylinders include:
- Single-Piston Master Cylinders: These master cylinders use a single piston to convert brake pedal pressure into hydraulic pressure.
- Double-Piston Master Cylinders: These master cylinders use two pistons to convert brake pedal pressure into hydraulic pressure.
- Power Brake Master Cylinders: These master cylinders use a power brake booster to amplify the brake pedal pressure.
Brake Pedal: The Component that Transfers Pressure to the Master Cylinder
The brake pedal is a critical component of the braking system, and it serves as the component that transfers pressure to the master cylinder. The brake pedal is typically mounted to the brake pedal assembly and contains the brake pedal linkage.
Wheel Hub and Steering Knuckle: The Components that Mount the Brake Caliper
The wheel hub and steering knuckle are critical components of the braking system, and they serve as the components that mount the brake caliper. The wheel hub and steering knuckle are typically made of steel or aluminum and are designed to withstand the high stresses and temperatures generated during the braking process.
