My MC has started acting up again after a year. Ordered a rebuild kit for it from Bevel Heaven, but I refuse to pay $19 for a "tube" (tool). Anyone here fashioned an alternative and done this rebuild?

Thanks in advance as always

Are you sure you can even do a rebuild? The ones built in the last decade or so can't be rebuilt AFAIK.
-Throttle's on the right, so are the brakes.  Good luck.

Fred @ Yoyodyne told me you can last year, but would have to fashion or buy a "tool." The tool  looks like this

I guess you'd rather buy a new master?  [evil]

Do you have dimensions for this tool?

No, figured I'd wait for the kit and see exactly how small the seal is, the description is as follows.

QuoteThis is a special tool we designed to press the special crush washer correctly into the end of your 12mm, 13mm or 15mm BREMBO master cylinder when installing a rebuild seal and piston kit. These tools will exert equal pressure on the washer so that it doesn't potato chip causing poor or no sealing. A must have when doing your brakes.

NOTE: These tools are applicable to those master cylinders with a crush washer NOT the type using a snap ring retainer system.

I got the 13mm kit, that's a bit over half an inch (.511)

You just need a piece of tubing to tap the washer in?

How about a deep socket?

Yep, in reading around that was one of the suggestions I saw. Was hoping someone here might have tried this on a old coffin. Does the clutch master have the same size piston as the brake on a '00 M750? If so, I've got an old one of those that I may turn into a guinea pig.

Typically clutch masters are smaller.

What bike do you have that has a 13mm brake master?

Single disc Ducs are 15mm and twin discs are 16mm IIRC.

Got an email from Steve @ Bevel Heaven and he said instructions come with the kit but in typical Italian fashion have nothing to do with task at hand... [clap]

Found a little info on generic brembo rebuild on a Laverda forum and the national Guzzi owners site. Anyway I'll see if I can't get this old clutch M/C apart this w/e.
