The Brake Authority Burly BA4052B brake pads embody the excellence of Made in France braking for demanding modern MTB practices. Developed under the leadership of Fabien Barel, DH world champion and braking perfectionist, these sintered metal pads offer exceptional longevity (5/5) combined with remarkable braking power (4/5) on Shimano Saint, Zee and TRP 4-piston calipers. Specially designed for Cross-Country, All-Mountain and Enduro disciplines, they incorporate the exclusive NoNitech technology (nickel-free) for reduced environmental impact and total respect for the cyclist.

Brake Authority performance and philosophy

Brake Authority combines Performance and Respect in every product. These pads are the result of a partnership with a renowned French manufacturer in the railway, automotive and motorcycle sectors, guaranteeing a professional quality level. The advanced sintered metal synthesis process ensures unmatched braking performance with high resistance at high temperatures, while preserving disc integrity thanks to a non-aggressive formulation. The Type B Burly classification positions these pads as the best compromise between mileage endurance and bite for intensive sport use and XC-AM-Enduro competition.

Technical highlights

• Remarkable to exceptional longevity: Durability rated 5/5, ideal for long rides and intensive use while respecting the disc.
• NoNitech sintered metal: Nickel-free composition (highly toxic mineral), environmental and health commitment without compromising performance.
• E-Bike optimization: Formulation adapted to the increased demands of electric-assist MTBs (weight, speed, repeated stress).
• Pre-bedded and ready to brake: Valuable time savings, immediate performance from installation without tedious bedding-in phase.
• Modulation and progressivity: Easy to modulate with excellent proportionality between lever effort and braking power, guaranteeing control and safety.
• 100% French manufacturing: Local production to reduce carbon footprint, recycled and recyclable packaging, used pad recycling process.

Extended 4-piston compatibility

The BA4052B pads are designed to replace original Shimano references D02S, D03S, H03A, H03C, N03A, N04C on a wide range of high-performance 4-piston calipers.

Technology and eco-responsible commitment

Brake Authority stands out with its eco-responsible specifications unique in the bike braking world. Since the brand's creation in 2008, numerous technical and cosmetic evolutions have been deployed: NoNitech technology eliminating nickel (highly toxic substance), used pad recycling process, 100% recycled and recyclable packaging. French production guarantees complete traceability and exceptional expertise inherited from the high-performance industry (rail, automotive, motorcycle). Burly pads offer excellent disc respect, limiting premature wear while ensuring consistent performance in dry and wet conditions. Their design prioritizes safety, longevity and control, three essential pillars for demanding riders in Enduro, All-Mountain and Cross-Country.
