Key Features:

• Ergonomic lever blade for comfortable and efficient control.
• 10mm internal brake lever piston for enhanced power and modulation.
• Adjustable lever reach to customize fit for various hand sizes.
• I-Spec B compatible for seamless integration with shifters.
• I-Spec EV adapter option for broader compatibility.
• Optimized for 2.3mm rotors (rotors sold separately).

2. Safety Information

Always prioritize safety when installing, operating, or maintaining your bicycle brakes. Failure to follow these instructions could result in serious injury or property damage.

• Professional Installation Recommended: If you are unsure about any installation steps, seek assistance from a qualified bicycle mechanic.
• Brake Fluid: Use only TRP-approved high-performance mineral oil. Do NOT use DOT fluid, as this will damage the system.
• Brake Pads: Only use TRP-approved organic/resin brake pads. Metallic brake pads are NOT compatible with this system.
• Rotor Compatibility: Ensure your rotors are compatible with hydraulic disc brakes and are of the correct thickness (2.3mm recommended).
• Regular Inspection: Periodically check brake levers, calipers, hoses, and pads for wear, damage, or leaks.
• Test Brakes: Always test your brakes in a safe area before riding after any maintenance or adjustment.

4. Setup & Installation

Proper installation is crucial for optimal brake performance and safety. Refer to your bicycle's frame and fork manufacturer's instructions for specific mounting requirements.

Pre-Installation Checklist:

• Ensure your frame and fork are compatible with disc brakes.
• Verify that your rotors are 2.3mm thick and clean.
• Gather necessary tools: Hex keys, torque wrench, cable cutters (if hose length adjustment is needed), mineral oil, bleed kit.

Installation Steps:

1. Mount the Caliper: Attach the brake caliper to your fork (front brake) or frame (rear brake) using the appropriate CNC-machined adapter and mounting hardware. Ensure the caliper is centered over the rotor and tighten bolts to manufacturer's specified torque.
2. Mount the Lever: Position the brake lever on your handlebar. The left-hand lever is typically for the front brake. Adjust its position for comfortable reach and finger access, then tighten the clamp bolt.
3. Route the Hose: Carefully route the brake hose along your frame, securing it with cable ties or frame clips to prevent snagging. Avoid sharp bends.
4. Connect Hose to Caliper (if not pre-attached): If the hose is separate, connect it to the caliper following the specific instructions provided with the hose and fittings.
5. Bleed the System: After installation, the brake system must be properly bled to remove any air bubbles and ensure consistent performance. Refer to the 'Maintenance' section for detailed bleeding instructions.
6. Adjust Lever Reach: Use the adjustable reach mechanism on the lever to set the distance from the handlebar to the lever blade for your preference.

5. Operating Instructions

The TRP Slate EVO brakes offer precise control and powerful stopping. Understanding proper operation is key to maximizing performance and safety.

Brake Lever Adjustment:

• Reach Adjustment: Use the small dial or screw on the brake lever body to adjust how far the lever sits from the handlebar. Set it to a position where your index finger can comfortably reach and apply pressure.
• Lever Angle: Adjust the angle of the brake lever on the handlebar so that your wrist remains straight when your fingers are on the lever. This reduces fatigue and improves control.

Braking Technique:

• Progressive Braking: Apply brake pressure gradually. Avoid sudden, hard braking, especially on loose surfaces, to maintain traction and control.
• Front vs. Rear Brake: The front brake provides most of the stopping power. Use both brakes simultaneously, with slightly more emphasis on the front, for effective and controlled deceleration.
• Modulation: The Slate EVO offers excellent modulation. Practice feathering the levers to control your speed precisely without locking up the wheels.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your TRP Slate EVO brakes.

General Maintenance:

• Cleaning: Keep calipers, rotors, and pads clean. Use a clean cloth and disc brake cleaner. Avoid oil or grease on braking surfaces.
• Hose Inspection: Check brake hoses for any signs of wear, cuts, or leaks. Replace damaged hoses immediately.
• Fastener Torque: Periodically check that all mounting bolts are tightened to the manufacturer's specified torque.

Brake Bleeding:

Over time, air can enter the hydraulic system, leading to a spongy lever feel and reduced braking power. Bleeding the brakes removes this air and restores performance.

Note: Always use a TRP-approved bleed kit and mineral oil. Follow the specific instructions provided with your bleed kit for the most accurate procedure.

Brake Pad Replacement:

Brake pads wear down with use and should be replaced when the pad material is less than 0.5mm thick or if performance degrades.

1. Remove Wheel: Remove the wheel from your bicycle.
2. Remove Retaining Pin: Locate and remove the brake pad retaining pin from the caliper.
3. Remove Old Pads: Carefully pull out the old brake pads from the caliper. Note their orientation.
4. Push Pistons Back: Use a clean pad spreader or plastic tire lever to gently push the caliper pistons back into their bores.
5. Install New Pads: Insert new TRP-approved organic/resin brake pads, ensuring they are correctly seated. Reinstall the retaining pin.
6. Reinstall Wheel & Test: Reinstall the wheel and pump the brake lever several times until the pads engage the rotor. Test brakes in a safe area.
