Does anyone else's rear brake squeak?
i do
Is there anything to do to fix it?

lock it up a few times and it wont squeek anymore
Alright?
no like going down the road doing 60 stomp on it and kick the bike out sideways. do that a couple times and it won't squeek anymore.
alright
all lies, ive locked 'er up a few times now, been going harder on it lately to get rid of it. '05 and its getting kind of annoying.
ok, the joke was that after you highside then it won't squeek anymore, but nobody got it. try replacing the pads with some ebc sintered ones. some bikes squeek some don't, you got a squeeker.
Yeah i get the squeek about 1 out of every 10 times. I have an 05 with 1450 miles on it. It did it frequently in the begining when I first got it, but it is going away slowly. It seems to come on more frequently when just starting out riding also.
I have an 05 with a little over 4,000 miles and it has always squealed. I hardly ever use it because of this. Mine does it 9 out of 10 times :x Brakes hot or cold. Bout to try some different pads myself...

Oh god yes, the SQUEAK! 1,100 miles on my 05 so far (in a little less than a months time, too!) and the squeak is STILL there. It's kinda emberassing when you roll up next to a hot chick and the only reason she looks over is because she can hear the INSANELY LOUD REEEEEEEEEEEEE. :oops: I've jammed the rear brake so much and it doesn't go away. I use the shaZam! out of it in hopes that it wears it down enough and stops squeaking... No go. I use the rear brake 90% of the time when I need to brake. Front brake is only used when I'm below 5mph coming to a stop or I need to brake HARD, like for some jackass in front of me (or the skid stop test at the DMV.)
mine never squeaks...
then again, I never use it
synthetic brake grease on the back of the pads and the two pins that hold the brake pads.

Are you saying that you use the rear brake exclusively? Without the front brake? :?
You're kidding, right?
I think the rear wheel alignment is a big part of the rear brake squeak problem. See recent thread http://www.gstwins.com/forum/viewtopic.php?t=21635
Different linings also affect it, but most other solutions like using brake harder or lubing brake parts are temporary at best.
Been fighting this problem for years on old Honda front discs after 30k miles and on GS500 rear discs from new on. It's not a new issue on bikes.
My '04 used to squeak like crazy, but then I started using my front brake for most of the braking. It really helps a ton, plus you can actually stop when you want to. They still squeak when I use them too much, but that just lets me know to back off the rear brake and apply more front brake. :dunno:

No, not exclusively, but when it's possible that I
can use it exclusively I do in hopes that I wear it down enough to stop the squeel. It's gotten slightly better but I just want the squeel to go away. For example though, if I need to slow down just a smidge, I apply the rear brake. If I need to slow down a slot like say coming to a stop, I apply both the rear and front brakes as evenly as possible. Coming off the interstate I use the engine for braking mostly until I'm down to a speed that the rear brake can safely take over. So I do use the rear more, but only in a futile attempt to kill the squeak!

I look at the squeal as a warning...it reminds me that I'm on the rear brake. :dunno:
I'm sure you're aware of this, but I'll say it anyway...
Whenever the motorcycle is decelerating, weight shifts to the front...this is physics, and it's unavoidable. This lightens the rear wheel and removes traction. Reduced traction on the rear makes it that much easier for the rear to lock up, since as soon as you break traction it takes very little brake pressure to stop the rotation of the rear wheel. In fact, the front brakes take advantage of the weight shift...if you want to stop hard you can apply enough brake to load the front, compress the front forks, and increase traction in the front, allowing you to brake harder there (it also allows you to turn quicker, but that's a different discussion). The overwhelming majority of your stopping power comes from the front.
Take my advice for what it's worth (probably not much), but if you're going to use the rear brake a lot, I recommend practicing locking up the rear brakes in relatively safe environments (i.e., parking lot at relatively low speeds travelling in a straight line). I'm not trying to criticize...you probably already do this, and chances are you have a lot more experience than I do.
I spent most of last Sunday working on hard deceleration, and more than a few times got the rear locked up. My conclusion was that it's shockingly easy to inadvertently let that happen. It's very, very disconcerting if you're not prepared for it (even if you are), doubly so if you need to work the rear wheel back straight when it starts to slide out sideways. I've also found that it's more difficult to gauge the pressure on the rear than it is for the fronts, and if you're braking while downshifting I'd think there's increased risk of breaking traction on the rear (since the rear might stutter if you don't hit the shift right).
Sorry if this sounds preachy...that's not my intent, but everything I've read or been told has advised against excessive use of the rear brakes on motorcycles...sportbikes specifically because of the weight dynamics.
If you can only use the back break... your not riding fast enough.

FYI
the front brake is good for 75-90% of your braking
the only time i use the rear... panic stopping and ORE's...wet grass
Mine squeeks when i am braking. The lighter the brake is applied the more is squeeks. It doesn't squeek when moving without braking. I know my wheel is aligned properly, just adjusted the chain. I think it is just something you will have to get used to. If you go with a rear pad made from softer material, as davipu suggested, it probably wouldn't squuek anymore.
'05 stock rear brake pad = squeak
is sad, but I also realized about this problem within days of riding.
i will change my brake pads one day... when I have extra cash.

Well, there's your problem...
Try more like 70% front and 30% rear... Or at very least 50/50.
The front brake is better at stopping you anyway.

Yeah, I did read that thread and a guy or two said once the pads and rotor were worn down enough to "create its own grooves" the squeek went away which is why I was using my rear brake as much as possible. :(
Badger - I really do appreciate your input. Gives me much to consider. I also appreciate that you didn't yell at me for being a stupid uneducated noob and instead you offered constructive criticism.
Now, to move on to your points for sake of discussion. I never thought about the weight shift being significant enough to cause the rear wheel to skid. I have yet to run into that problem but most likely because I never hit the rear brake hard. If I do require any significant amount of braking power, the front brake is mostly used.
I actually have practiced braking hard using the rear brake. It was the day before I was due to take my driven (ridden?) test at the DMV and I was running through all the tests to make sure I was comfortable with the course. Believe me, the motorcycle tests here are RIGOROUS. Anyways, I was only up to ~20mph before I locked up the brakes and the rear tire did actually skid a few times when I didn't hit the front brake as hard. When I did things just right though, I was able to slam the front and rear brakes with no skidding. In real life practical situations, skidding is avoided at all costs and the front brake is my best friend. :)
I probably haven't encountered any of the things you've warned me about because a) The GS500F isn't a very powerful bike and b) I actually ride it nice 99% of the time and don't drive like a maniac. :P
Anyways, preach on brotha! I'm always open to constructive criticism. In fact, I feed on it. I'm always looking for ways to refine skills and sometimes (a lot of times) a new perspective and someone elses knowledge and wisdom really goes a long ways.

Yeah, that's what I did for the first few days when I got the bike was use mostly the front brake because the rear did squeak so bad. But then I thought... Man I just want this squeak to go away! No real reason, just a pet peeve of mine. Although, since I got on my rear brake regimen, it has started to squeak less frequently and less loud but after 1,200 miles I think it's here to stay. :guns:
