MINI AND MOKE DUAL OUTLET BRAKE MASTER CYLINDER – GENUINE – [GMC227]
PRODUCT OVERVIEW
Genuine AP Lockheed dual outlet brake master cylinder, boxed and made in the UK.
This front-to-rear type brake master cylinder is the later model dual circuit master cylinder, introduced in 1985. It features a stepped bore design and was used as a replacement for previous dual master cylinders fitted from September 1978 through to 1988, before the later built-in servo type master cylinder was introduced.
A brake master cylinder is a safety-critical component, so using a genuine AP Lockheed unit gives better confidence in fitment, quality and braking reliability.
