Pinça do freio

A pinça do freio é um componente relevante para a segurança do veículo que é exposto a altas cargas térmicas e mecânicas. Quando o pedal do freio é pressionado, o fluido de freio é enviado para o pistão da pinça do freio, que pressiona as pastilhas de freio contra o disco. Os projetos e o número de pistões variam de acordo com o tipo de veículo e motor.

Brake caliper made of aluminium with labeling

Caratteristiche e requisiti di lavorazione

Solid aluminium brake calipers are used for weight reduction. They are ideal for high performance vehicles and heavy models that require a rapid brake response.

Safety-relevant component
High demand on quality
