Product Information

Full details

The EBC MD6135D fixed brake rotor is designed for motocross, enduro, and ATV riders who demand consistent, reliable stopping power in harsh off-road environments. It is engineered with high-strength materials to withstand extreme conditions, offering riders enhanced control and safety during technical trail riding or racing. While this rotor is built for durability, its fixed design lacks the thermal dissipation capabilities found in more expensive floating rotors, making it best suited for riders prioritizing structural simplicity and ruggedness.

Do I need to replace my brake pads when changing the rotor?

It is highly recommended to install new brake pads whenever you install a new rotor to ensure even wear and optimal performance.

What is the internal diameter of the mounting hole spacing?

Troubleshooting

Brakes feel spongy after installation

This is typically a hydraulic issue. Bleed your brake system to remove air bubbles from the brake lines.

Audible squealing during light braking

Ensure the rotor surface is clean of oil and grease. Check if the brake pads are glazed and lightly sand them or replace if necessary.

Vibration during braking

Check that all 6 mounting bolts are tightened to the correct torque specification and ensure the rotor is not warped.

Pros and Cons

Pros

High-grade steel construction for long-lasting wear resistance
Precise fitment ensures easy installation
Excellent thermal management for standard off-road use
Solid fixed design reduces mechanical complexity
Reliable performance in mud, sand, and water

Cons

Not intended for high-speed road racing applications
Fixed design may be prone to heat buildup during sustained aggressive braking compared to floating discs
Requires professional inspection when replacing pads

Setup, Compatibility & Care

To ensure optimal safety, always verify that your vehicle's hub matches the 133 mm bolt pattern and 6.5 mm hole specification before installation.

Preparation: Clean the hub surface thoroughly of rust or debris to ensure the rotor sits perfectly flush.
Installation: Use a torque wrench to tighten the six bolts to the manufacturer's specified setting, typically in a star pattern to distribute pressure evenly.
Bedding-in: After installing the new rotor, perform a series of gentle stops to 'bed-in' the brake pads to the new disc surface.
Maintenance: Periodically check for scoring or thinning beyond the 4 mm tolerance. If the rotor shows signs of deep grooves or discoloration, replace it immediately to maintain braking integrity.
