CM10-30 Overhaul Instructions for 10-30, 10-30A, 10-30C, & 10-300
This kit had everything I needed to rebuild the Cleveland 10-30 cylinder(s) in my 1979 Piper Warrior.
People getting ready to overhaul a brake master cylinder should be told that they will need more than just this overhaul kit to do the job. Theyâ€™ll need to get the instructions online. They need to buy some Dow 50 grease and then the instructions call for fabrication of a special tool which requires a lathe. After getting the grease and making the tool, I finally rejected three parts in my 2 master cylinders and since those parts were so bloody expensive, I bought a pair of Matco cylinders instead of going ahead with overhauling the Cleveland cylinders.
The kit needs Dow Corning 55 O-ring grease, absolutely unacceptable that you find out after you buy the kit!
It is designed to be used with 5606 or like hydraulic fluid. We could not find any documents to show how well, or if, it can be used with DOT3 brake fluid.
