New floating brake disc for Harley-Davidson, 4,000 km Alpine road test

TRW Aftermarket

The new TRW brake disc for Harley-Davidson guarantees maximum performance, without compromise. It is based on a two-part design and a system of ten floating bobbins. A practical test over 4,000 km has proven: even under extreme temperatures, it retains its shape, remains low-noise and offers a significantly greater performance than fixed disc versions.

A Harley-Davidson Heritage was the ideal test vehicle for the new floating brake disc from TRW. After all, its front brake system has only a single brake disc which is under extreme strain. During the summer, the Heritage took a 4,000 km journey across the Alps. The brake had to work extremely hard, especially during long pass descents with a pillion and full luggage load. In fact, under these conditions the brake disc is exposed to extreme temperature loads which are not even reached during racing use. But the new brake disc from TRW mastered all challenges with the greatest ease. It allowed the Heritage to be safe, quiet and sturdy during all braking manoeuvres. Even after 4,000 km under extreme conditions, the brake disc was still in perfect shape!

The floating disc with type approval from TRW offers a significantly higher performance than fixed versions. This is ensured by the optimised weight and the well thought-out concept. The outer ring made of a high strength steel alloy is floated to the CNC milled inner ring made of black anodised aluminium. This reliably prevents warping and deformation, even if the outer ring expands under extreme thermal load. At the same time, the floating brake disc perfectly absorbs any vibrations or oscillations and minimises any braking noise.

The new floating brake disc adds another top product to the large TRW special range of brake pads, brake discs, brake fluid, clutch kits, custom handlebars and sport handlebars for Harley-Davidson. They offer additional braking performance for the legendary bikes while also featuring an attractive design!
