Question Front brake howling?

Any body else having this issue lately? Mine has started howling when coming to a stop. It's annoying. Any ideas on how to fix?

I'll try removing the pads and re surfacing them, then the rotors.

Could the pads still be bedding in? I wouldn't do anything to them yet except maybe give them a spray of brake cleaner.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s

very common with new bikes (break pads)- get some speed and hit the breaks really hard. it will go away!!! They just need to mold in.

I just thought it would be worse when I got the bike. But now at 2000 miles it's getting a bit worse.

I know how to remove the pads and de glaze them. I'll take a look.

With Brakes in general this can be an issue if you use moderate brakes as this tends to glaze the surfaces. As mentioned previously a few hard stops can take care of it. Alternately, riding at a bit of speed and dragging the brakes for 10 or 20 seconds can have the same effect.

You can also put some anti squeal product on the back side of the brake pads. that should absorb vibrations and quiet you brakes.

Talking

Brakes still howling just before you come to a stop.

Anyway, this morning I went on a "cram on the front brake until the damn ABS comes on and the rotors are red hot" ride to see if it helps.

I was noticing some howl, then all of a sudden i had no front brakes this morning. After I pulled into a gas station, I found this:



Turns out, my lack of front brake was the lack of rotor between the pads on my front right rotor. Notice the missing lower bolt? The upper bolt had backed out too, but luckily was still there. The hanging caliper also knciked the shit out of my rim. I managed to push the pads apart, and put the caliper back on with only the upper bolt and limped it home.

I bought the bike Friday, and she now has 343 miles on her. Not even time for the first service. To top it all off, all of my local dealers are closed on Mondays. I can't even go get a new bolt. Called Suzuki customer service and they agree that my dealer (who did a shit job with setup) will be buying me a new rim, completing a thorough brake inspection (possibly even ordering a new caliper), and I'm going to demand a free 500 mile service.

What a morning, eh?

Well, I am a little confused by the pictures. Clearly the caliper was at one time installed on the fork tubes and had both bolts attaching it. One bolt it now missing, I assume after it backed out and fell off somewhere. There is one bolt in the mount for the caliper....did you put that bolt back in there for some reason? If both bolts fell out I can certainly see how the caliper would bang against the rim, but with the one bolt still holding it you are lucky it didn't "wedge" against the rim somehow as it rotated around?

The lower bolt fell out somewhere. The upper bolt backed out enough for the caliper to come off the mount, then somehow stayed in place. So right now, I am missing one bolt.

At some point the caliper was hanging completely and bangin against the rim.

I got lucky on this one. Really lucky
