MG TD TF 1500 - MC measurement
|About to start rebuild of my MC. But my reamer needs either new stones, which aren't easily available, or a complete new reamer, which is not expensive. |
What diameter do I need?
|I think you mean a hone. I used the smallest expandable type that I could find and it did a fine job.|
|Yup - a hone. I guess the size determines the name!|
I've found a ¾" hone/reamer. Is that too big?
|It could be just me but I've never had good luck with honing and rebuilding master cylinders (or wheel cylinders) and usually resort to having them sleeved or just get new ones.|

|I guess it depends how badly scored the bore of the cylinder is - a hone is only going to remove a very small amount of material, so it won't fix deep scores. Sorry can't remember the size exactly, but as I said, mine was the smallest expanding type that I could find and it only just fit. You are going to need replacement seal kit, so just measure the diameter of those.|
|If MC is not scored a simple solution to remove blemishes and surface rust is:
1/2 inch rod the length of the bore plus an inch. Using a hacksaw cut a 1 inch longitudinal slot in one end of the rod. Wrap emery strip around the rod after securing the end in the sawn slot until you reach a diameter the ID of the bore. Place other end of rod in a drill chuck and switch drill on. Move the emery wrap up and down the bore to sand the complete surface of the MC bore.
I have recovered MCs, slave cylinders and brake cylinders on many occasions using this method.
Ensure you completely flush the cylinder with metho after using this process.
