DescriptionThe whole story

There is less rotor on an FS 450 to absorb the heat a hard stop makes. ZCOO cuts the B005 at 102.2 by 42.0 mm to fill the Brembo caliper window of the FS 450. On the Husqvarna FS 450 the B005 is now available in EXR, the compound that carries ZCOO's endurance programme.

Key Features

  • Heat spreads across the whole 102.2 by 42.0 mm face instead of concentrating at the leading edge
  • Direct replacement for the standard Brembo pad on the Husqvarna FS 450 - no shims, no spacers, no modification
  • New backing plate alloy, specified with the compound instead of carried over from the EXC Endurance mixture EXR replaces
  • Identical B005 geometry to the EX Race version, so switching compounds on the FS 450 changes nothing about fitting
  • Machined, not moulded: the B005 plate is cut to the Brembo outline rather than pressed to an approximate one
  • Better cold performance and higher thermal stability than the compound it succeeds - fewer laps lost bringing the pad in

Construction and Material Quality

The B005 is a racing part in the way it is made, not only in the way it is sold. A Brembo caliper spreads under peak line pressure, and a plate that yields with it moves the contact patch onto the pad's edges. None of it is visible once the B005 is in the Brembo caliper, which is precisely the point.

Performance and Feel

The change from EXC to EXR is not only in the friction mixture. ZCOO specified a new backing plate alloy for the compound, and on a pad that reaches the top of its window repeatedly the plate is doing structural work throughout. For a rider working on braking technique on an FS 450, that is exactly what an upgrade should buy.

Fitment and Compatibility

Listed by ZCOO for the Husqvarna FS 450, model years 2015 to 2025, on the Brembo caliper. The same B005 shape covers 117 further machines in the 2026 catalogue. Before ordering, check that your caliper takes a pad of 102.2 mm length and 42.0 mm height. Front axle exclusively - there is no rear B005.

Road Approval

No ECE R90 type approval is documented for this pad. It appears neither in ZCOO's own catalogue nor on the European distributor's site, and no approval number is printed on the packaging data available to us. ZCOO itself describes the compound as suited to competition machines and road machines alike, but that is a description of the mixture, not a type approval. Until the distributor confirms an approval in writing, treat this as a track and competition part: in Germany a replacement brake pad without ECE R90 approval may not be fitted to a motorcycle used on public roads. Ask us before ordering if you need this clarified for your machine.
