ICOOH IC4 Toyota Rear Big Brake Kit
The ICOOH IC4 Toyota rear brake kit is developed for selected Toyota chassis requiring more controlled rear braking response, improved brake balance, and increased rear rotor capacity. It uses an IC4S3 forged aluminum 4-piston rear service caliper with 355×28mm or 380×28mm brake disc options for 18-inch and 19-inch wheel applications.
IC4S3 4-Piston Rear Caliper
Four 27mm pistons distribute hydraulic pressure across the rear brake pad to support predictable rear braking response and consistent pad contact.
355mm / 380mm Options
Select 355×28mm or 380×28mm according to the vehicle chassis, rear hub, parking-brake system, mounting bracket, wheel size, and available internal clearance.
Parking-Brake Integration
Depending on the vehicle, the rear kit may retain the original drum-in-hat or mechanical parking brake, or require a vehicle-specific auxiliary parking-brake arrangement.
Toyota and Lexus Fitment
Applications cover selected Toyota passenger cars, MPVs, SUVs, off-road vehicles and sports cars, plus selected Lexus shared-platform models.
Generally matched with selected 18-inch wheels. Actual fitment depends on the rear hub, parking-brake structure, wheel offset, inner barrel, spoke profile, center-bell offset, and bracket.
Generally matched with selected 19-inch wheels. The larger rotor requires additional inner-barrel clearance and must be checked against the service-caliper and parking-brake positions.
The supplied Toyota and Lexus workbook also contains 330mm rear brake configurations for newer vehicles. Those 330mm applications are not included in this product and must not be converted to 355mm or 380mm without a separate chassis, bracket, rotor-offset, parking-brake, and wheel-clearance review.

Rear Brake Fitment Confirmation
Matching the vehicle model, production year, or wheel diameter does not automatically confirm rear brake compatibility. The service caliper, brake disc, center bell, rear hub, parking-brake system, mounting bracket, brake line, and wheel must be checked as one complete system.
- Confirm the exact Toyota or Lexus model and production year.
- Provide the complete chassis code and VIN where possible.
- Confirm the original rear caliper and brake disc dimensions.
- Confirm the rear hub and axle configuration.
- Confirm mechanical, drum-in-hat, electronic, or auxiliary parking-brake structure.
- Select the 355×28mm or 380×28mm brake disc option.
- 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 whether one or two rear calipers are required per side.
- Disclose spacers, hub changes, suspension modifications, or previous brake upgrades.
- 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. Wheel offset, inner-barrel diameter, spoke profile, service-caliper position, parking-brake position, mounting bracket, center-bell offset, and rear-hub structure must all be verified.
