Dinky little Master Cylinder???

OK, ordered a new Master Cylinder, ended up with this little 2"x3", if that, master cyl.
Compared to the old one that was 3"x4"?

Wondering if I was just sent the wrong one,
or if that's all a VT500C really needs??

At this point, just kind of sitting here amazed at it...
haven't checked if it fits yet


Ride paranoid. Don't let anything distract you.
Keep the paint side up, wear the lid & leathers.

Probably your original one swelled up in the heat down there.

It really doesn't matter what size the master cylinder is as long as it can push enough fluid in a single stroke to activate the brake cylinder.

Sounds like it might be worth slapping on and seeing if it'll do the trick
I've got to check out the rest of the brake system first tho...
have been looking for a replacement brake caliper at the wheel,
but nothing on Amazon for that, unless I"m asking it the wrong questions.

If you want Honda OE master cylinder, you probably have to order from an authorized dealer. On Amazon, you may get something that will work, but not necessarily look like the original.

I doesn't take a lot of fluid to activate the piston. Unless you've got some mongo sized, dual discs up front. Should be fine.

You proved to be absolutely correct, size does not matter! LOL

However, the new master cylinder made all the old stuff,
start doing old stuff problems
So rebuilt the front caliper, replaced the front brake line...
and put in new pads, of course.

Now it'll stop on a dime

Couple months testing report...still doing great!
No issues at all. It's maintained its fluid level properly.
Quite happy!

Thanks for reporting back on the longer term use.
So many reviews are of stuff are based on a couple of days experience.

reservoir size is not important, master cylinder piston size and caliper piston(s) size(s) are what determine how hard/soft it feels and how well it works.
