Project Mu Brake Pads (REAR)

2023+ Toyota GR Corolla

PSR004

Overview:

Project Mu Brake Pads for the rear of the 2023 and newer Toyota GR Corolla deliver a balanced blend of performance and refinement. Designed specifically for drivers who prioritize clean wheels and low noise, these pads provide reliable initial braking force while minimizing dust generation. Ideal for decorated vehicles, wagons, and sedans, they maintain the aesthetic appeal of your wheels without sacrificing stopping power. The copper-free formulation also reflects Project Mu’s commitment to environmentally conscious materials.

Key Features:

These brake pads incorporate advanced technology to ensure consistent performance and durability:

• Copper-Free Material: Environmentally friendly composition that reduces harmful copper content without compromising friction.
• Wide Operating Temperature Range: Effective from 0 to 400 degrees Celsius, suitable for everyday driving and spirited use.
• Stable Friction Coefficient: Maintains a consistent coefficient of 0.34 to 0.38 mu for dependable braking feel.
• Gas and Dust Management: Central slits efficiently discharge gases and pad residue generated under intense friction, reducing brake fade.
• Chamfered Edges: Precision-cut pad corners minimize unpleasant brake squeal caused by pad-to-rotor contact.
• Pre-Heat Treated: Pads are pre-burned during manufacturing to eliminate excess materials, reducing gas generation and fade during initial use.
• Reinforced Backplate: Steel backplates are 20% stronger than OEM to prevent warping under high piston pressure, ensuring pad integrity and safety.

Construction & Design:

Project Mu brake pads are engineered with a focus on durability and environmental responsibility. The friction material is copper-free, reducing environmental impact while maintaining excellent braking performance. The pads feature a robust steel backplate that resists distortion, preventing material separation and ensuring long-term reliability. Central slits in the pad design allow for efficient gas and residue evacuation, maintaining consistent contact with the rotor and preventing brake fade. Additionally, chamfered edges are incorporated to reduce noise and improve overall braking comfort.

Performance & Sound

These pads offer a quiet braking experience with minimal dust output, making them well-suited for drivers who want to keep their wheels clean and noise levels low. While brake squeal can occasionally occur due to factors such as rotor aging, rust, or environmental conditions, the chamfered design and pre-treatment processes significantly reduce this risk. The pads deliver stable initial bite and consistent friction, providing confidence in everyday and spirited driving scenarios.

Installation & Fitment:

Project Mu rear brake pads are designed as direct replacements for the 2023 and newer Toyota GR Corolla, requiring no modifications for installation. They fit precisely to OEM specifications, allowing for straightforward installation by professional technicians or experienced enthusiasts. No additional quenching or special break-in procedures are necessary beyond standard bedding-in practices.

What's Included:

• Pair of rear brake pads (2 pads total)
• Installation instructions

Ideal For:

These brake pads are perfect for GR Corolla owners who seek a balance of clean aesthetics, low noise, and reliable braking performance. They are especially suited for daily drivers, enthusiasts with decorated vehicles, and those who want to maintain wheel cleanliness without sacrificing safety or brake feel.
