8 Piston Big Brake Kit for S800

The SAVANINI’s S800 caliper is the caliper with the most pistons in the current mass-produced calipers. 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.

S800What is unique about the  caliper?
The domestically developed calipers specifically designed for large off-road vehicles have a larger number of pistons and better linear foot feel. After rigorous multiple environmental testing experiments, their performance has improved by ≈ 35% compared to the original calipers. Paired with performance brake pads, they can meet the requirements of intense driving in various environments, including mountain running, race tracks, and other special environments, and can handle them with ease.
