Matco Aircraft Landing Systems’s MCMC-4K master cylinder uses a REMOTE reservoir. The MCMC-4K can be used in individual or dual brake applications. Buna-n orings are used in this assembly. Mil-H-5606 aircraft hydraulic fluid or compatible fluids are recommended. DOT5 may be used but not DOT5.1 which contains glycol. DOT3 and DOT4 may not be used and will cause immediate damage to the seals.
The MCMC-4K master cylinder measures 6.44 inches from end to end and 5.87 inches from mounting hole to mounting hole. A 0.625 inch diameter piston is used. Available stroke is approximately 1.388 inches and displacement is 0.43 cubic inches. The ports on all Matco Aircraft Landing Systems master cylinders are 1/8 inch NPT (except the MC-4E).
The MC-4K has fixed length shaft. See the MCMC-4, -4A, -4D, or -4G for units with the clevis. The MC-4K is the shortest length unit with 0.43 cubic inch displacement
