This page explains how Brake Caliper is classified within Motor Vehicle Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A hydraulic or mechanical device that applies clamping force to brake pads against a rotor to slow or stop a vehicle.
Technical details and manufacturing context for Brake Caliper
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Bore Diameter | 30–60 mm | Determines clamping force; larger bore for heavier vehicles. |
| Piston Area | 700–2800 mm² | Affects brake torque and pedal feel. |
| Maximum Operating Pressure | 12–20 MPa | Exceeding may cause seal failure. |
| Clamping Force | 15–60 kN | Critical for braking performance. |
| Operating Temperature Range | -40–150 °C | Beyond range may degrade seals and fluid. |
| Piston Stroke | 2–5 mm | Affects pad wear compensation. |
| Weight | 1.5–4.5 kg | Unsprung mass affects ride and handling. |
| Material Grade | A356–A380 | Aluminum alloy for strength and heat dissipation.ASTM B85 |
| Surface Treatment | 20–30 μm | Zinc coating thickness for corrosion resistance.ISO 1461 |
| Leakage Rate | ≤0.5 cm³/min | Excessive leakage indicates seal damage. |
| Bolt Hole Pattern | 4×100–5×120 mm | Must match vehicle hub mounting. |
| IP Rating | IP54–IP65 | Protects against dust and water ingress.IEC 60529 |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The brake caliper houses the brake pads and pistons. When hydraulic pressure is applied, it forces the pads against the rotor to create friction, slowing or stopping the vehicle.
Common materials include cast iron and aluminum alloy. Aluminum alloy is often used for weight reduction and heat dissipation, while cast iron offers durability.
Selection depends on vehicle weight, braking requirements, rotor size, and mounting interface. Key parameters like bore diameter, piston area, and clamping force must match the vehicle's hydraulic system. Always verify with the manufacturer.
Signs include brake fluid leakage, uneven pad wear, reduced braking performance, or a pulling sensation during braking. Excessive leakage or seal damage indicates the need for inspection or replacement.
