Brembo GP4-RB 108mm Caliper

The Brembo GP4-RB is carved from billet in two pieces and finished in anodised black with a glossy red Brembo logo. Four aluminium pistons of 30 and 34 mm in a light aluminium-alloy body make it a clear step up from a stock caliper.

This listing is the left-hand caliper in black finish. It has 4 pistons of 30-34 mm in an aluminium body machined from solid, works with discs 32-34 mm wide and comes with brake pads. It weighs about 0.9 kg. The matching right-hand caliper is Brembo part number 120B47341. Brembo part number 120B47340.
