Mountain bike brake parts aren't universal. Before ordering new pads, rotors, adapters or hoses, identify the exact brake and confirm each component's specifications.
Start with the caliper model, not just the brand
Pad shapes differ between brake families, even within the same brand. Find the exact caliper model and, when relevant, the model year. Compare the manufacturer's supported pad shape or part number against the replacement listing. A match in appearance is not sufficient proof of compatibility.
Choose a suitable pad compound
Organic (resin) and sintered (metallic) pads can have different noise, wear, heat and wet-weather characteristics. Not every rotor is compatible with every pad compound, so check both the pad and rotor manufacturer's recommendations. Plan to bed in new pads according to their instructions.
Verify rotor diameter, thickness and attachment
Rotor selection includes diameter, thickness and hub mounting standard (such as 6-bolt or Center Lock). Check the caliper's accepted rotor thickness, the frame or fork's maximum permitted rotor diameter, and whether an adapter is required. Do not assume an adapter or rotor will fit solely because the nominal diameter matches.
Brake hoses and fluid must match
Hydraulic brake systems may specify mineral oil or DOT brake fluid, and their hoses, fittings and bleed procedures vary. Never mix fluid types or substitute an unapproved fluid. Use only manufacturer-compatible parts and follow the relevant technical manual.
Shop and get fitment help
- Shop brakes, rotors, pads and adapters.
- Browse workshop tools for manufacturer-approved service tasks.
- Review brake service options.
Brakes are safety-critical. If you're uncertain about fitment, installation or braking performance, consult a qualified mechanic. You can also contact Freeman Gravity Sports with your caliper model, rotor size and bike information before ordering.
