Project Mu HC M1 Brake Pads (REAR)

2023+ Toyota GR Corolla

PHMR004

Overview:

The Project Mu HC M1 Brake Pads represent the flagship model of the HC series, engineered to deliver exceptional braking performance for the 2023 and newer Toyota GR Corolla. Designed to excel in a wide range of driving conditions—from everyday city commuting to spirited sports driving—these rear brake pads offer a perfect balance of control, stability, and durability. Featuring a super graphite metallic compound, they provide outstanding and consistent braking force even under high temperatures, ensuring confidence and safety on every drive.

Ideal for enthusiasts seeking reliable, high-performance brake pads that minimize dust and maintain strong pedal feel, the HC M1 pads are a premium upgrade that enhances the braking system’s responsiveness and longevity without compromising comfort.

Key Features:

Project Mu’s HC M1 brake pads incorporate advanced technology and thoughtful design to optimize braking performance and user experience:

• Wide Temperature Range: Operates effectively between 50°C and 800°C, maintaining stable friction under extreme conditions.
• Super Graphite Metallic Material: Minimizes brake dust generation for cleaner wheels and reduced maintenance.
• High Friction Coefficient: Offers a friction coefficient between 0.41 and 0.55, delivering strong and consistent stopping power.
• Gas and Dust Venting Slits: Central slits efficiently discharge gases and pad residue generated during intense braking, preventing brake fade.
• Chamfered Edges: Carefully cut corners reduce unpleasant brake squeal caused by pad corner contact.
• Pre-Heat Treated: Pads are pre-processed to burn off unnecessary materials, reducing gas generation and fade during initial use.
• Reinforced Backplate: Steel backplates are 20% stronger than OEM to prevent warping and ensure pad integrity under heavy braking.

Construction & Design:

The HC M1 pads are crafted from a super graphite metallic compound that balances high friction performance with low dust output. This advanced material composition allows the pads to maintain consistent braking force across a broad temperature spectrum, from everyday driving heat levels to the elevated temperatures experienced during aggressive track use. The inclusion of gas venting slits in the pad design helps mitigate the fade phenomenon by allowing gases and debris to escape, preserving brake effectiveness.

Project Mu’s commitment to safety and durability is evident in the use of a reinforced steel backplate that resists distortion under piston pressure, preventing pad material separation and potential brake failure. Additionally, the chamfered edges reduce noise, enhancing the overall driving experience without sacrificing performance.

Performance & Sound

While the HC M1 pads deliver strong and stable braking performance, users should note that initial braking force will be reduced until the pads and rotors reach optimal operating temperatures. This break-in period is essential for achieving peak performance. The pads are designed to minimize brake dust and squeal; however, some noise may occur due to factors such as rotor aging, rust, brake dust accumulation, or environmental conditions. Proper maintenance and rotor condition will help ensure quiet operation.

Installation & Fitment:

These brake pads are specifically designed for the rear brakes of the 2023 and newer Toyota GR Corolla. Installation requires no modifications and fits directly onto the factory calipers. It is important to allow sufficient time for proper break-in after installation to ensure optimal braking performance and pad longevity. Always verify compatibility with your specific vehicle model before purchase.
