| 1 | Integrated Mechanical Parking-Brake Caliper | Compact and midsize passenger cars with rear disc brakes | Single piston; commonly 30–42 mm piston diameter range | Cast iron or aluminum, depending on vehicle weight and corrosion requirements | Mechanical lever integrated into the caliper | Solid or ventilated rear rotors, generally about 9–12 inches in diameter | Broad replacement coverage Simple service parts and widely understood adjustment procedures | Confirm lever orientation, cable attachment, piston rewind direction, and mounting-hole spacing |
| 2 | Electronic Parking-Brake Caliper | Modern passenger cars and crossover vehicles with electronic parking brakes | Single piston with an electrically driven parking-brake actuator | Aluminum or coated cast iron | Integrated electric motor and reduction mechanism | Rear ventilated rotors are common on heavier vehicles | High vehicle-system integration Supports electronic parking-brake architectures without a separate cable | Verify connector type, actuator position, software service mode, polarity, and electronic compatibility |
| 3 | Low-Drag Floating Caliper | Fuel-efficient compact cars and urban vehicles | Single piston with sliding guide pins | Aluminum body or lightweight cast iron bracket-and-body construction | Usually mechanical cable or electrically actuated mechanism | Small to medium solid or ventilated rear rotors | Efficiency focused Reduced pad drag can help limit heat generation and rolling resistance | Check guide-pin condition, seal design, pad abutment clearance, and bracket alignment |
| 4 | Heavy-Duty Single-Piston Caliper | Pickup trucks, utility vehicles, vans, and light commercial vehicles | Large single piston; often approximately 40–55 mm, depending on application | High-strength cast iron or reinforced aluminum | Mechanical cable, drum-in-hat system, or electronic actuator | Large ventilated rear rotors with increased thermal capacity | Load-capable design Suitable for higher axle loads and frequent stop-start operation | Match axle rating, rotor thickness, pad area, caliper bracket strength, and wheel clearance |
| 5 | Aluminum Fixed Multi-Piston Caliper | Performance road cars, sports sedans, and premium applications | Two or four opposed pistons, depending on braking-system design | Aluminum alloy with corrosion-resistant surface treatment | Often uses a separate parking-brake system or an integrated electric actuator | Large ventilated rotors; rotor diameter and thickness must be matched precisely | High stiffness and control Opposed pistons can provide even pad loading and consistent pedal response | Confirm piston sizes, pad shape, bridge clearance, brake-line thread, and master-cylinder compatibility |
| 6 | Corrosion-Resistant Coastal-Climate Caliper | Vehicles operated in marine, humid, snowy, or road-salt environments | Single piston or dual piston, based on the original braking system | Coated cast iron or treated aluminum with stainless or protected hardware | Mechanical or electronic, depending on vehicle platform | Rotor and pad dimensions must follow the original vehicle specification | Environmental durability Protective coatings and sealed components help reduce corrosion-related seizure risk | Review salt-spray testing, coating thickness, fastener material, boot quality, and drain-path design |
| 7 | Regenerative-Braking-Compatible Caliper | Hybrid and battery-electric passenger vehicles | Usually a single-piston floating caliper, with vehicle-specific variations | Aluminum or coated cast iron | Commonly an electronic parking brake | Rear rotors may be smaller than those on comparable combustion vehicles, depending on regenerative-braking strategy | Suitable for reduced friction use Designed for vehicles where friction braking may be used less frequently | Check electronic service procedures, corrosion protection, low-drag performance, and compatibility with the vehicle control system |
| 8 | Drum-in-Hat Parking-Brake System | Large SUVs, performance vehicles, and vehicles requiring high parking-hold capacity | Rear service caliper is commonly single-piston; parking brake uses separate internal shoes | Cast iron or aluminum caliper with a steel drum section inside the rotor hat | Separate mechanical parking-brake shoes inside the rotor hat | Ventilated rear rotors with an integrated drum-in-hat section | Strong parking hold Separates service-brake and parking-brake functions | Verify drum-in-hat diameter, shoe adjustment, rotor hat depth, wheel offset, and backing-plate clearance |
| 9 | Remanufacturable Service Caliper | Fleet vehicles, older vehicles, and markets prioritizing repairability | Typically single piston with replaceable seal and boot kits | Cast iron or aluminum suitable for cleaning and surface restoration | Mechanical or electronic, depending on the original platform | Uses the original rotor diameter, thickness, and pad dimensions | Lifecycle value Supports seal replacement, inspection, and controlled refurbishment where regulations permit | Inspect bore condition, piston surface, bleeder threads, guide pins, and remanufacturing traceability |
| 10 | Modular Caliper for Multi-Market Platforms | Vehicle platforms sold across regions with different brake packages | Single or dual piston with interchangeable brackets or application-specific hardware | Aluminum or coated cast iron | Mechanical cable or electronic actuator, depending on regional specification | Multiple rotor and pad combinations may exist within the same vehicle family | Configuration flexibility Useful for distributors serving different wheel, axle-load, and regulatory specifications | Use VIN or exact vehicle data; confirm left/right position, regional brake package, ABS requirements, and homologation documents |
