Did you read my post #44 above?

Many bikes with low miles have had weak braking reported. Just because yours works well doesn't mean everyone else's does too...

Since we can't ask the man that decided to put two discs on the bike why he did it, any opinions on the reason are of course pure speculation.

I think it was a combination of the specs being off a bit and using a harder than needed lining on the shoes. I've had other new bikes with drum brakes that did not take so long for the brakes to bed in.
The good news is most Vulcans out there now have been around long enough for their brakes to be "broken in" ...

Only now and then does one show up that has low miles....or came from an owner that never used the rear brakes. That kinda makes some sence if you can picture a new owner to a new bike that finds the rear brake weak or "almost useless" so they simply get in the habit of not using it.

So the cure for those weak rear brakes (provided nothing else is wrong) is start using them as much as possible. Soon, they should break in and start working the way they are supposed to.

Anyone and everyone of course should get in the habit of using BOTH brakes, front and rear, all the time.

Sorry for the double posting , but I did want to mention that because of the bike having shaft drive...ACCT's and hydraulic adjusting litters one gets the idea they wanted a bike that was fairly maintenance free.

One aspect Jerry didn't touch on is the brake pads on his one disc bike will wear out twice as fast as a duel brake setup. That may have been another possible reason they used two discs up front too....

I too have a weak rear brake. The markings show that the brake shoes should be quite new.

I found this in the manual but I do not really understand what it is all about:

When you tighten to a sung fit and then apply the brake, the axle will shift to center of pressure caused by the brake shoes. This allows both shoes to have equal pressure and provide your best braking. If not centered you are only getting max pressure on one shoe. Best that I can explain it. But I could be wrong.

When I bought my VN750 it only had one front brake, but still 2 rotors. I thought I would have trouble braking, but none yet Was thinking about going back to 2 calipers, but really don't want to put any money into that project since it seems to work just fine.

i personally love the look of the two rotors up front but what i want to know is how the damn stealership gets away with chaging 350 bucks for one you would figure the price for parts on thes 750's would be lower since the thing was made practically unchanged for 20 frickin years and yet they still dont have anything in stock wtf

the reason they don't have any in stock is because most people don't need to change them. and the bike has been out of production for 6 years. you can however get a set of aftermarket disks for realitivly cheap... even if they don't say that they are made for the VN750, I have found that the CX500 disks are teh same, and I see on the CX forum every month where some one has adapted another sports bike disk to their set up.
