Shimano Resin Disc Brake Pads Instruction Manual

Introduction

Thank you for choosing Shimano Resin Disc Brake Pads. These pads are engineered to provide consistent, quiet, and reliable braking performance for your bicycle. This manual provides essential information for the proper installation, operation, maintenance, and troubleshooting of your new brake pads to ensure safety and extend their lifespan.

Key Features

• Provides 50% more wear resistance compared to the previous J03A model.
• Alloy radiator cooling fins enhance pad life and reduce brake fade during prolonged use.
• Delivers consistently smooth and quiet braking power.
• Designed for optimal performance in both dry and wet riding conditions.

These Shimano Resin Disc Brake Pads (Model EBPJ05ARFBS) are compatible with a wide range of Shimano brake calipers. Please verify your caliper model against the list below:

• BR-M9000, BR-M9020, BR-M987, BR-M985
• BR-M8100, BR-M8000, BR-M785
• BR-M7100, BR-M7000, BR-M675, BR-M666
• BR-M6100, BR-M6000, BR-M615
• BR-S700, BR-RS785, BR-R7

Setup and Installation

Proper installation is crucial for safe and effective braking. If you are unsure about any step, it is recommended to consult a professional bicycle mechanic.

An open cardboard box containing multiple sets of Shimano Resin Disc Brake Pads, neatly organized in individual compartments. The box also holds small metal springs and pins, which are typically included for installation.

1. Preparation: Ensure your bicycle is stable, preferably on a repair stand. Gather necessary tools, including a hex wrench set, flathead screwdriver, and clean rags.
2. Remove Wheel: Remove the wheel from the bicycle to access the brake caliper easily.
3. Remove Old Pads: Locate the retaining pin or bolt that holds the brake pads in place. Remove it carefully. Using a flathead screwdriver, gently pry apart the old pads and remove them from the caliper. Note the orientation of the old pads and springs.
4. Clean Caliper: Clean any dust or debris from inside the brake caliper using a clean rag. Avoid using solvents that could damage seals.
5. Install New Pads: Insert the new Shimano Resin Disc Brake Pads along with the new spring (if provided) into the caliper. Ensure the spring is correctly positioned between the pads. The cooling fins should face outwards.
6. Secure Pads: Reinsert the retaining pin or bolt through the pads and caliper, securing them in place. Ensure it is tightened to the manufacturer's specifications.
7. Reset Pistons: Gently push the brake caliper pistons back into their bores using a plastic tire lever or a dedicated piston press tool. This creates space for the new, thicker pads.
8. Reinstall Wheel: Reinstall the wheel, ensuring it is properly seated in the dropouts and the quick release or thru-axle is tightened securely.
9. Bed-in Procedure: After installation, it is essential to bed-in the new brake pads. Ride the bicycle and perform approximately 20-30 moderate stops from a speed of about 15-20 mph (25-30 km/h) without coming to a complete stop. Allow the brakes to cool between sets of stops. This process transfers pad material to the rotor, optimizing braking performance and reducing noise.

Operation

Shimano Resin Disc Brake Pads are designed for consistent and reliable stopping power. When the brake lever is squeezed, hydraulic pressure forces the caliper pistons to push the brake pads against the rotor, creating friction that slows or stops the wheel. The resin compound provides a good balance of power, modulation, and quiet operation, especially suitable for general riding conditions.

Maintenance

• Regular Inspection: Periodically inspect your brake pads for wear. Replace them when the pad material is worn down to approximately 0.5mm thickness or if the wear indicator groove is no longer visible.
• Clean Rotors: Keep your brake rotors clean and free of oil, grease, or dirt. Contaminants can significantly reduce braking performance and cause noise. Use a dedicated disc brake cleaner or isopropyl alcohol.
• Check for Contamination: If pads become contaminated with oil or grease, they may need to be replaced as cleaning them effectively can be difficult.
• Brake Fluid: Ensure your hydraulic brake system has sufficient and clean brake fluid. Refer to your brake caliper's manual for fluid type and bleeding procedures.
• Rotor Condition: Check rotors for excessive wear, warping, or damage. A worn or damaged rotor can compromise braking performance and accelerate pad wear.

Troubleshooting

• Squealing/Noise:
  • Cause: Contaminated pads/rotors, improper bed-in, loose caliper, worn pads.
  • Solution: Clean rotors with disc brake cleaner. Re-bed pads. Check caliper mounting bolts for tightness. Replace worn pads.
• Reduced Braking Power:
  • Cause: Worn pads, contaminated pads/rotors, air in hydraulic system, glazed pads.
  • Solution: Replace worn pads. Clean or replace contaminated pads/rotors. Bleed brake system (professional recommended). Re-bed pads to remove glazing.
• Brake Lever Feels Spongy:
  • Cause: Air in hydraulic system, low brake fluid.
  • Solution: Bleed brake system and add fluid if necessary (professional recommended).
• Pads Rubbing Rotor:
  • Cause: Misaligned caliper, sticky pistons, bent rotor.
  • Solution: Realign caliper. Clean and lubricate pistons (consult professional). True or replace bent rotor.
