S45C small 4 piston caliper

SAVANINI's S45C caliper is a small 4 piston caliper currently developed specifically for medium/small vehicles.It adopts aluminum alloy forging technology and has high rigidity, high tensile strength, high toughness and high density. Compared with cast aluminum alloy calipers, the rigidity of the SAVANINI’s caliper has increased by about 50%, which effectively reduces the risk of caliper breakage during application. Compared with ordinary external dust covers, the built-in double oil seal design makes the brake feel and reaction speed more sensitive. It has excellent braking performance. After anodizing, vacuum coating CVD color fixation effectively solves common problems such as paint cracking and paint shedding, giving it a metallic texture and brilliant color. After installation, the entire wheel hub looks more attractive, perfectly coping with various road conditions, whether it is daily travel or sightseeing, it can also go on the track.

S45CWhat are the unique features of calipers?
One of the small 4 piston calipers developed by SAVANINI specifically for medium/small cars.In order to better match the small and medium-sized calipers designed for vehicles, the four piston can better adapt and match the vehicle to improve braking performance. After rigorous multiple environmental testing experiments, its performance has been improved compared to the original calipers≈20%↑,In order to better match the small and medium-sized calipers designed for vehicles, the four piston can better adapt and match the vehicle to improve braking performance.
