ICOOH IC4 Audi Rear Big Brake Kit
The ICOOH IC4 Audi rear brake kit is developed for selected Audi chassis requiring improved rear braking control, a more balanced brake response, and a larger rear brake disc configuration. Depending on the vehicle and parking-brake structure, the kit may use an IC4S3 service caliper with a mechanical or auxiliary electronic parking-brake caliper.
IC4 Series 4-Piston Caliper
The compact four-piston rear caliper provides controlled hydraulic pressure distribution while maintaining a practical rear-axle installation envelope.
355mm / 380mm Disc Options
Select a 355×28mm or 380×28mm rear brake disc according to the Audi chassis, wheel diameter, rear hub and available clearance.
Parking-Brake Integration
Applications may require a mechanical parking-brake caliper or an auxiliary electronic parking-brake caliper alongside the IC4S3 service caliper.
Audi Chassis Fitment
Fitment is organized by model, production year, chassis family, rear axle structure, parking-brake type and wheel specification.
Generally recommended for selected 18-inch wheel applications. Actual clearance depends on the inner barrel diameter, wheel offset, spoke profile, rear hub and parking-brake arrangement.
Generally recommended for selected 19-inch wheel applications. This is the primary configuration recorded for many newer Audi electronic parking-brake platforms in the supplied fitment data.

Rear Brake Fitment Confirmation
Matching the Audi model name, year or wheel diameter does not automatically confirm compatibility. Rear big brake kits must also integrate with the vehicle's service brake, parking-brake system, hub, bracket position and wheel clearance.
- Confirm the exact Audi model and production year.
- Provide the complete chassis code and VIN where possible.
- Select the 355×28mm or 380×28mm brake disc option.
- Confirm whether the vehicle uses a mechanical or electronic parking brake.
- Confirm whether a dual-caliper rear setup is required.
- Provide the wheel diameter, width and offset.
- Confirm whether the wheels are OEM or aftermarket.
- Measure the inner wheel barrel and spoke-to-caliper clearance.
- Confirm the original rear brake disc and hub specification.
- Disclose existing spacers, suspension changes or previous brake modifications.
- Provide clear photos of the wheel face and original rear brake assembly.
The 355×28mm configuration is generally recommended for 18-inch wheels, while the 380×28mm configuration is generally recommended for 19-inch wheels. Wheel diameter alone does not guarantee clearance. The wheel offset, inner barrel, spoke profile, service caliper, parking-brake caliper and mounting bracket must all be checked before ordering.
Confirm Your Audi Rear Brake Fitment
Send your Audi model, year, chassis code, preferred brake disc size, parking-brake type, wheel specifications and rear brake photos before checkout. ICOOH can help verify the appropriate IC4 rear brake configuration for your vehicle.
