I was riding yesterday and for some reason when I used my rear brakes, it started to make a high pitch squicking sound. It was riding fine before that so I really dont know what is going. Any suggestions what is going on with the brakes?
PS
I'm a noob at this
i've heard of this happening, the rear squeal. try searching? and im sure someone will hop up with another thread or their own info for you before too long.
are your pads low and need replaced? Check the thickness of the pads, sounds like you need to replace.
I just replaced them not too long ago so I am positive its not the pads . . .
Rear brake squeak is a GS500 trade mark.
Some have gotten rid of it by changing rotors. Others have put some grease on the Shim of the brake pad - where the piston pushes on the pad. Cause That is where the squeak comes from. Others have realigned their rear wheel.

That's weird because I get a squeak on my front brake...

check the pads, rotor surface, brake fluid. could be surface rust on the rotor if it's been sitting a while which will rub off eventually, given that the rotor is still good and the pads are still good.
Im pretty sure everyone here gets that. I cleaned all the brake dust off of the disk real good once and it seemed to help for a few days
I have this too and it is driving me insane. Got a different rotor still squealing! It started when I put in this last set of pads. What can I do?

Tg317Please indicate the what brand name and P/N was on those "noisy" new pads. The info would be very helpful.
Thanks!
Also. . .
A search on "rear brakes" for the GS500 will overwhelm. There is actually a poll someplace about rear brake noise/problems/usage. As I recall it, the majority of the answers were to simply avoid using the rear brake at all, (problem solved). GStwin member
"mister" hit the nail on the head with his
trademark statement. And I'd like to add "not much feel or modulation either".
I'm currently battling "F" bike wind-noise demons but the rear brake problem is certainly on the Hit-List of GS500 maladies that can be rectified.
Not that you asked but hey, it's a forum. . .
In short it would seem that going with an organic FF pad material,
Using typical Acrylic Polymer disc brake squeal compound,
and substantially widen the center channel, i.e. machine a groove about 20mm wide down the center of the pad would at least be a good starting point for some experimentation on noise & feel issues.

Finding FF pad material is probably a hopeless adventure so GG may have to do.
Regardless, it's the center groove that is the big factor. Will post results, as this rear brake issue is indeed on the list of stuff to do!
As for the FRONT brake noise mentioned previously. . .
Agreed: A clean & inspect issue.
The simple, predictable, 310mm single rotor front brake on the GS500 is well suited to its task.
One of the few components on the GS I can find no reason to "make better", (and know better than to experiment with in my butcher shop). (http://mysite.verizon.net/vze2wc9e/grin47.gif)

If they are not worn below service limit they could be glazed. Pull em out, rub them over with some sandpaper and chamfer the leading edges then try again.
Funny story #112: I was once out with a pal, the pads in his GPz550 had been squealing for a while and it got to the stage where he got utterly pi**ed off with the situation, So, about 75 miles from home and while I had a brew from my flask he pulled them out and rubbed them on a kerbstone......it worked for about 6 months :thumb:
They are the EBC pads not sure of the number. They are about two months old! I use my back brake alot but have changed that do to the earsplitting sound! OUCH

This is one of those annoying things that some bike are prone to get, the rear on my GS500E was pretty noisy and the bandit rather less so but it's still there, perhaps because i don't use the rear brake as much as i should.
Assuming that the pads are OK probably the best option is to clean the disc(s) but be carefull about what you use, some people recomend a solvent like kerosene/parafin but remember this is essentially OIL followed by a degreasant like "gunk" to remove all oil traces. I have recently used a specific spray-can fluid made for the job and it seems to have improved both squeal and braking.
Rear brake squeal is a very common GS500 complaint. I've had a lot of it over the past 11 years and 160k miles of GS usage. I've never bothered with the compounds put on the pads between the backing plates and caliper pistons. Sanding the pads to rough them up a bit will help briefly but it comes right back. Different linings can make a difference too but I think the single most important thing on the GS is the rear wheel alignment. I've personally eliminated squeal a couple times by adjusting the rear wheel alignment and others here have reported the same results.
All my previous Hondas had very bad front brake squeal develop after about 30k miles usage as the front rotors became glazed and I tried everything to fix it. Finally tried the EBC Kevlar pads advertised to eliminate squeal 20 years ago and it worked, squeal was eliminated with the same rotors. So when my first GS rear brake started squealing I tried the EBC organic pads and got some relief but not like before. Don't think they are the same as the old ones that had the Kevlar in them.
About 3 years ago I discovered I needed some front pads in a hurry and got some EMGO pads locally that I decided to use until I could online order some EBC pads. Now 3 years and about 32k miles later they are still on the bike, look like they will go 40k miles total, and have never squealed a bit nor have the 2 sets of EMGO pads I used on the rear ever squealed a bit. I think they fall between the EBC Organic and EBC HH pads both of which I've used in stopping power and have a real good smooth feel, I've bought extra sets to keep on hand so I won't have to use anything else, they are $24 a set currently locally, a real bargain. I still remain careful with my rear wheel alignment though.

I used "CRC" Disk Brake Quiet. It's red and gooey but I have not heard a peep out of them in 400 miles. The day I put it on, the squeak was gone! There is a spray on Kind and a paint on kind. I used the paint on kind but I think the spray would be better. You can put more coats on evenly with the spray. I put on one thick coat let dry then put another one on. You put it on the metal part of the brake pad or backside. I used a flexible type putty knife to apply it. I swear by this stuff! :bowdown: It was so nice to get rid of that! My bike had the stock Suzuki brake pads and I am good with those.
Good luck!
