Description
Jr. Sprint Fitment: Also fits D1 JRX and Lynk Jr. Sprint (junior sprint) chassis.
The black Paul Martin brake master cylinder is small, compact, and moves plenty of fluid for both front and rear caliper assemblies on a 600 Micro Sprint. Compact matters here – cockpit space in a Micro Sprint is measured in inches and the master cylinder competes with the driver for it.
Used on the D1 chassis and many other manufacturers cars, so it is a safe replacement on most 600s. Fluid flow is the spec that decides whether you get a firm pedal or a spongy one, and this one has margin.
Sold individually – specify front or rear application. Built to a standard that survives a season of dirt. In stock in Fresno, CA – 559.891.1901.
