The Shimano J04C Metal Brake Pad is an essential upgrade for mountain and road cyclists who demand consistent, high-performance stopping power in challenging terrain. Featuring integrated Ice-Technologies cooling fins, these pads are engineered for riders who experience heavy brake fade during long descents or wet conditions. While they offer superior durability and bite compared to resin pads, users should note that the sintered metal compound can be slightly noisier during initial bed-in periods and may require more frequent rotor inspections to prevent premature wear.

While physically compatible, always check your rotor's markings. Some ultra-lightweight rotors specify 'Resin Pad Only' and should not be used with sintered metal pads.
Yes, the kit includes new springs. It is highly recommended to replace the springs during every pad change to ensure proper tension and pad alignment.
Visually inspect the thickness of the friction material. If the material is less than 0.5mm thick, it is time for a replacement.
Yes, as long as your road bike uses one of the compatible Shimano brake calipers, such as the BR-R785 or BR-RS785.
The fins are part of Shimano's Ice-Technologies system, designed to increase surface area for cooling, which significantly reduces the risk of brake fade on long downhills.
Perform a bedding-in process by finding a flat, safe area and executing multiple controlled, hard stops from medium speed to transfer pad material to the rotor.
This typically indicates air in the hydraulic line. Bleed your brake system according to the manufacturer's manual.
Inspect for fluid leaks at the caliper piston or potential rotor contamination. Clean rotors with a dedicated brake cleaner if necessary.
Installation requires basic bike maintenance tools, including a rotor alignment tool and a pad spreader. Always ensure your rotors are compatible with metal pads, as some lightweight rotors are specified for resin-only use.
Compatibility: The J04C is compatible with Shimano BR-M9000, BR-M9020, BR-M8000, BR-M985, BR-M785, BR-M666, BR-S700, BR-R785, and BR-RS785 calipers.
Care Instructions: Keep your rotors free of oils, chain lubricants, and cleaning agents to prevent contamination. If you store your bike for extended periods in humid environments, periodically check the pads for surface oxidation or glazing, which can be lightly sanded away if minor buildup occurs.
