This component is for Rear Left. Confirm left versus right, front versus rear, rotor dimensions, and the compatible Alcon kit number before ordering.
Is this rotor interchangeable with a similar-looking Alcon rotor?
No assumption should be made from appearance or diameter alone. Match the exact MPN, side, offset, thickness, hat or ring interface, vane direction, and compatible brake kit.
What is included with Alcon ALADKR2175X757C24L?
The verified package includes One ALCALADKR2175X757C24L rear left rotor ring. Hats, rings, fasteners, and opposite-side components are included only when expressly listed.
What should be checked before installing a replacement rotor?
Verify rotor thickness and condition, correct directional orientation, clean mounting surfaces, compatible pads and hardware, wheel clearance, fastener torque, runout, and the required bedding procedure.
Installation Instructions
- Raise the vehicle on a lift or axle stands and remove the rear left wheel.
- Remove the rear caliper and support it aside without disconnecting the brake line.
- Remove the worn rotor assembly from the hub.
- Inspect the rotor hat and hardware, replacing worn floating pins or retainers as needed.
- Install the ALCALADKR2175X757C24L rotor ring onto the hat assembly.
- Reposition the caliper over the rotor and torque the mounting bolts to specification.
- Reinstall the wheel and torque to factory specification.
- Bed in the new rotor with several gradual stops from moderate speed.

Shop Alcon big brake kits, calipers, rotors, replacement rings, brake pads, brackets, service hardware, and rotor temperature products by exact manufacturer part number. Match the complete vehicle, axle position, factory brake package, rotor dimensions, caliper family, wheel clearance, and included components before ordering. Alcon Big Brake Kits Alcon brake kits combine application-specific calipers, rotors, brackets, pads, lines, and installation hardware in front, rear, or complete-vehicle configurations. Piston count and rotor diameter do not establish fitment by themselves; the hub, knuckle, axle, factory brake package, wheel barrel, spoke profile, and kit part number must all match. Race, Street, Truck, and Off-Road Applications Select the brake system for the vehicle's actual use. Repeated track braking, towing, larger tires, added vehicle mass, and off-road driving can require different rotor capacity, pad compound, heat management, and service intervals.
