Project Mu HC M1 Rear Brake Pads

For 1983–1987 Toyota Sprinter Trueno / Corolla Levin AE86 with Factory Rear Disc Brakes & 1985–1987 Toyota Corolla Sport GT-S AE86

Overview

Project Mu HC M1 Rear Brake Pads bring the flagship HC-series street-sports compound to the rear disc brakes of 4A-GE Toyota AE86 models. The compound is designed around linear pedal control, stable braking at high temperature, and lower dust output than traditional graphite-metallic high-friction pads.

HC M1 uses super graphite metallic friction material with an applicable rotor temperature range of 50–800°C and a 0.41–0.55μ friction coefficient. The wide operating range and progressive response make it suitable for performance street driving, autocross, drift, and circuit use.

Key Features

  • 50–800°C applicable rotor temperature range
  • 0.41–0.55μ friction coefficient
  • Super graphite metallic friction material
  • Linear pedal control and predictable modulation
  • Stable friction at elevated temperatures
  • Reduced brake dust within Project Mu's HC-series graphite-metallic range
  • Designed for street-sports and circuit use
  • Rear axle application for AE86 rear disc brakes

HC M1 Compound

HC M1 is tuned to provide braking force that builds progressively with pedal pressure, helping the driver make precise balance corrections under hard braking. Its high-temperature stability supports repeated performance use while its dust-conscious formulation makes it more practical for a street-driven performance car than many traditional metallic track-oriented compounds.

Used with an appropriately matched front compound, the rear HC M1 pad can form part of a balanced AE86 brake setup for drivers who want predictable response from street temperatures through track-level heat.

Vehicle Fitment

Project Mu AE86 Rear Brake Pad Comparison

Brake Pad Primary Use Rotor Temperature Friction Coefficient Character
TYPE NS Daily / Street 0–400°C 0.37–0.40μ Street-focused with emphasis on lower noise and dust
B-Force Performance Street / Canyon / Autocross / Light Track 0–500°C 0.32–0.45μ Additional thermal capacity while retaining street usability
TYPE HC+ Aggressive Street / Track Day 0–800°C 0.43–0.58μ Higher-friction compound with a very broad operating range
HC M1 Performance Street / Track Day 50–800°C 0.41–0.55μ Linear modulation with strong high-temperature stability
Club Racer RC09 Dedicated Circuit / Competition 300–800°C 0.42–0.55μ Race-focused compound for sustained high-temperature braking

TYPE NS is the street-focused choice for regularly driven AE86s where cold response, reduced dust, and reduced noise are priorities.

B-Force is the next step for a harder-driven street car. Its 0–500°C range adds thermal capacity for canyon driving, autocross, and occasional light track use without requiring elevated brake temperature before working effectively.

TYPE HC+ substantially increases friction capability while retaining a 0°C lower operating threshold, making it a strong aggressive-street and track-day crossover.

HC M1 provides a more refined high-performance character with linear pedal control, high-temperature stability, and a 50–800°C working range.

Club Racer RC09 is the dedicated circuit option. Its 300°C minimum operating temperature makes it substantially less suitable for normal cold street use.

Selection Guide
