Brembo GP4-RS Calipers 108mm (pair)

These calipers are forged monobloc design, with 108mm hole centres, for universal fitment on Japanese radial forks. and are priced as a pair with pads

these calipers are R&T (Road & track) spec, come ready fitted with sintered pads and retain the dust seals, to protect the pistons and seal from road grit and grime

A more compact cousin of the M4 calipers, the GP4-RS is an evolution of the M4 concept - a smaller overall package, with smaller 30mm pistons, means higher brake line pressures are needed to generate the same braking forces - therefore these calipers are better suited to a master cylinder with a smaller lever ratio, or bore - Brembo suggest a RCS17 - we have successfuly matched these calipers with all our offered 19x18mm master cylinders, but do not recommend using any 19x20mm master cylinder
