I hardly use my back brakes, and already had to replace them, only 3k on the bike. The dealer showed me the brake pads. They're so small! why would buell put such tiny brakes on such a fast bike!?

I have over 6K and mine show almost no wear. Are you sure your not accidentally riding the brakes and possibly not aware of it?

Not to be rude or anything. But on a bike like this the back brake is almost always tiny. Sport bikes are alot more front end orienated which makes the rear almost useless in heavy and even moderate braking. As you hit the brakes the weight transfer of the bike plus yourself moves onto the front tire where the most traction is. The rear of the bike gets very light so it does not take much to lock up the rear wheel at all, making it unstable. (which can be usefull sometimes) The only time I find myself using the rear brake is in traffic or hitting it lightly right before I get the front brake to load the front tire.

Has anybody had any issues with the back brake emitting a loud howl? Any fixes?

Only once and that was when it was 40 degrees outside. The exhaust blowing on the back brake caused a bunch of condensation to build up. When I hit the rear the water was causing the howl.

when i first got my 1125 the rear brake pads were actually dragging the rotor all the time accelerating wear. broke the bleeder open to releive a little pressure and has been free turning unless applied ever since.

Is that what that noise is? I was thinking it was something in the belt drive. Didn't even think of the brake. .

Seems to happen the most to me around 40 mph give or take. I've gotten used to it but it's always be eating at the back of my mind what it was.

Dealer told me that its not just the 1125R's that have had the problem of the howling brake. They said there were other 08' Buells with the same problem. As of know there is no rhyme or reason ... which is frustrating. Dealer mentioned something about "tech tips" that they were trying to get some info from. I don't know about you guys, but when mine starts to howl, it almost feels like the bike doesn't want to stop ... its a little un-nerving.

I have owned a lot of sport Bikes and all Five buells I have had had the least amount of Bake Brake. They could just take it off and save the weight as its clear they dont want you to use it.

I think the rear brake is good for 100k miles. You just have to follow the basic rules of rear braking. "Only Use the Rear Brake on June 27 every other leap year"

U guys seriously don't use your rear?
WTF?! Are you never in traffic or around town? Do you ever make cornering adjustments? I have a Firebolt and use mine regularly (just not as often as front of course).

use it to flash the brake light while engine braking, and when i'm in gravel/grass. that's it.

as for braking for corner adjustments, it's called trail braking.

I am thinking about getting one of these for the brake lever...I sometimes find my foot fumbling to find the toe peg on the rear brake....just wish that it was $20 for a SET.

This 11 is at 6k miles and I have had the howl once in a while, in the past.

I hardly use the back brake...only when in the wet/rain. My front already shows that fact! From a street riding standpoint, I should tap it more! Proper braking practice should include a combination of both although the most does rely on the front end stopper...

Prior brake howl/squell related situations, it was always found that the pads were vibrating, causing similar noise...due to the minor clearances and w/o any dampening against related hardware (piston bodies).

Take a trip to a local auto parts store and request their brand of brake pad backing compound. Buy it.

Pull the caliper, remove pads, clean and finger with purchased (silicone looking and feeling product) liquid, let flash dry and reassemble.

Then, adjust your rear brake for plenty of end play at the lever...no preload. Verify rear spins freely.

Cycle brake lever a few times to "seat" and "bed" the pads to their new cushions.

Test ride. Hit the rear brake often to allow a running set.

Crack bleeder screw after the rear brake has been used and while still "hot"...bleeding into a clear tube and bottle. If there was any fluid seen then you were preloaded...if not, all good, she's in a relaxed state...just don't allow air back into the fluid track!

You shouldn't hear a howl again...unless the rotor is warped...refer to the NEW manual for runout tolerance test if such happens, mm

P.S. The words "Normal" or "The way it is" is not to be deemed the gospel...or corrected. Nor should it be accepted as such or why would we question it here?

Good origin post!: )

They do make a big difference Fresno! On both sides even.
Yes they are pricey but worth it to me.
