A:
If air pressure is used to remove the secondary piston, you should place the open end of the cylinder bore approximately 25 mm (1 inch) from a padded workbench or other surfaces to catch the piston when it comes out of the bore and applies low air pressure very carefully to ease the piston out of the bore.

01/11/2022 Q: What should be noticed about master cylinder reservoir filling?
A:
We should not use fluid that has a petroleum base and a container that has been used for petroleum-based fluids or is wet with water. And we should keep all fluid containers capped to prevent contamination.

01/11/2022 Q: What should be cautioned in disassembling Master Cylinder?
A:
You can not hone the master cylinder bore. When the brake master cylinder is overhauled, it is recommended that the cylinder body be replaced rather than CLEANED UP by honing the bore. The master cylinder has a hard, highly polished BEARINGIZED surface, which is produced by diamond boring followed by ball or roller burnishing under heavy pressure. Honing will destroy this hard smooth surface and cause rapid wear to the rubber cups.
