1. Product Description
The LPR Brake master cylinder (1834) is a precision-engineered hydraulic component designed by LPR, a premier Italian specialist in braking and clutch systems. Acting as the heart of the hydraulic braking circuit, this dual-circuit cylinder pressure-feeds brake fluid to the calipers and wheel cylinders upon pedal depression. It is manufactured from heavy-duty cast iron to prevent internal bore warping under severe, sudden heavy braking. Built specifically to match an original ATE system design, it comes outfitted with 4 output ports, making it an ideal choice for vehicles running independent lines to each wheel without secondary external splitters.
