Brake Parts & Hydraulic Brake Components
Build, service, or fine-tune your braking system with performance brake components for off-road, race, and custom vehicle applications. Shop Wilwood master cylinders, brake calipers, pads, rotors, residual pressure valves, balance bars, pedal components, mounting hardware, and replacement brake parts.
Brake performance depends on more than the caliper at the wheel. Master cylinder bore size, pedal ratio, hydraulic pressure, brake bias, caliper piston area, rotor size, and pad compound all work together to determine pedal effort and braking control. Whether you're building a manual brake system from scratch or servicing an existing setup, choosing components that work together is critical to predictable braking performance.
| Component | What It Does | Why It Matters |
|---|---|---|
| Master Cylinder | Converts pedal movement into hydraulic pressure | Bore size affects pedal travel, effort, and pressure |
| Brake Caliper | Uses hydraulic pressure to clamp the rotor | Piston area affects clamping force and fluid requirements |
| Brake Rotor | Provides the friction surface for the pads | Diameter, thickness, and mass affect braking torque and heat capacity |
| Brake Pads | Create friction against the rotor | Compound affects bite, temperature range, modulation, and wear |
| Balance Bar | Adjusts pressure distribution between two master cylinders | Allows front-to-rear brake bias adjustment |
| Residual Pressure Valve | Maintains low pressure in the brake circuit | Helps maintain consistent pedal response in certain system layouts |
| Brake Pedal Assembly | Transfers driver input to the master cylinder | Pedal ratio directly affects hydraulic leverage and pedal effort |
