Brake Caliper Upgrades

I have seen some of the Concours people upgrade their brake calipers on their front brakes. The brakes look 100% identical to ours (single piston).

Somebody made some brackets to adapt a 4 piston caliber from a zx6e. I'm impressed and interested...

Stock Caliper (looks like ours)


Upgraded:

Where there's a will there's a way. Lots of potential issues though:

Would our master cylinder be sufficient for this type of application?

Would it work with our rotors?

Would we need dental work after grabbing the handle a little hard?

If I were to go this far to put these "upgraded" calipers on, I'd also go the extra step to put on a matching Master Cylinder, assuming of course that it fit the diameter of the handle bars.

I'd be most worried about them working with the rotors.

The increased braking power would be a concern as well. These bike already have impressive breaking power and can lock the front wheel easily enough as it.

......I'd rather wake up in the middle of nowhere then in any city on earth.

My first concern would be with the stock master cylinder not being able to handle the upgraded calipers too. My other concern is that once you start replacing things, you may end up having to replace the calipers, the rotors, the MC, the brake lever because the stock one doesn't work with the upgraded MC, then the clutch lever because the stock one doesn't match the upgraded brake lever, and on and on.

don't you guys have dual rotors in the front? I thought the 750's were already pretty good at front brakes, just wondering

Yes, dual disc brakes up front on a 490# bike that work very well.

^yep. I think doing this is just overkill. As you're not installing better brakes, just adding more brakes. I can see doing this on a (older)Concours, it's a bigger heavier and faster bike with a wider front tire.
On the Vulcan the stock set up is already pretty good, many think its already an "overkill".
However, the stock master cylinder would be fine with doing this, as you're likely still pushing the same amount of fluid the same distance.

Now if you could install newer technology - larger diameter discs and high end (Brembo) caliphers that be nice...

I'd rather someone figure out how to put a disc brake in the rear..

I'm interested as to what you think is wrong with the drum brake on the back? I don't need more braking than the drum provides, it doesn't seize up with the salt from the roads in the winter, it doesn't need fluid changing/topping up/bleeding, no hoses to perish. It is a lot easier to clean and service. Front brake, yes, disc brake every time for max stopping power and almost no brake fade. So what have I missed ?

One can never have too many alternative forms of transport.
