MATCO mfg's MCMC-5 master cylinder uses a INTERNAL reservoir. The MCMC-5 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 reccomended. 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.
Shell embodiment on MC5 is not steel it is aluminum. The lower pivot is round and may not fit between a slab bracket. There is a PDF drawing with minimum extended length downloadable from Spruce.
I ordered an MC-5A. The wrapping was labelled MC-5A but the actual part inside was labelled MC-5 which is 1/2 longer than the A. Also, the inlet thread for the fluid was defective and had to be repaired. The bottom attachment point did not have a clean 0.187 dia hole to get bolt through. These had to be reamed to size.
Please view the MC-5 Drawing found in the "Documents" tab of this web page for all dimensional information.
No, these are intended for use on experimental aircraft only.
The system is bled from the caliper up. The reservoir is considered full when it is about 1/4" below the cap.
The reservoir on the MCMC-5 is vented to atmosphere and is not sealed. There is an o-ring under the cap but its function is to keep fluid from sloshing out. The reservoir has to be the highest point in the hydraulic system of fluid can run out of it.
