So my front brake pads have uneven wear.  the top of lets say pad A has about 1 mm left of pad left while the bottom of pad A has a significant amount of pad left while on the top of pad B there is a significant amount of pad left while the bottom of pad B has a very small amount of pad left (basically the wear of the pads are opposites)...i was wondering what can I do to fix it.  thanks

I would guess that either your front fork is slightly tweaked in the triple clamp causing the rotor to be at a slight angle or the caliper is not moving freely on the slides.  Try resetting the forks in the triple clamp and make sure caliper slides are lubed and moving freely.  Good luck   

hey i jst noticed u said "caliper slides lubed" im a newbie at bikes and i jst want to noe where is the caliper slides? Lol and wher shud i lube them plz gimme some umm guide or steps to lubing them how often to lube them as well

The Suzuki uses 2 different brake designs on the GS500.  The rear caliper is of a "fixed" design meaning it is bolted solidly to the bike and does not move.  When you push the brake lever it has a piston on each side of the rotor that pushes on the brake pads.  The front caliper is a "floating" design meaning it is mounted to the bike in a carrier and the caliper body actually moves when the brake is applied.  There are 2 pistons in the caliper but they are both located on one side of the rotor.  When you squeeze the front brake lever the pistons both push on one brake pad.  The applied force makes the caliper body move in the carrier which lets the caliper pull the other brake pad into the rotor.  The caliper is mounted on slide pins (circled in red below).  These pins must be cleaned and lubed to allow the caliper to work properly.  If the caliper does not slide freely it will reduce braking force and cause uneven pad wear.

Sounds like a pin slider problem as mentioned above.  Also make sure the pin sliders haven't been lubed with the wrong grease, must be a brake lube that won't attack rubber bushings.  I put some wheel brg grease on the pin sliders once when I was out of brake lube and the bushing #6 in the diagram above swelled up and stuck and caused the caliper to chicken as brakes were applied.  I removed the rubber bushing and the brake worked fine until I got a new bushing and installed it but it rattled a bit on sharp bumps reminding me to get the bushing back in there.

HI, sounds to me like you have a 1 sticky piston in your caliper,check for your front brake binding,if so you may need a seal kit for caliper,sometimes a seal will drag alongside the piston making it stick or piston gets that manky gets stuck (common in winter) If your Caliper floats ok,and it doesn`t bind,remove front wheel and watch your pads while appyling brake if uneven check brake pots.

Good point, I use a heavy weight silicone grease.  Didn't think about a frozen piston, another possibility.

Apart from all the ideas these guys have had ... you may also have a disk that is uneven. Front disks come too tin from the factory ... and I'd definitely change em in 15-20K for sure ... less if you have had caliper issues. And some pads eat disks ... if you ahve run one of those then went to a different pad, you may now have the disk eat the pad up.
Either way sort the problems all in 1 sweep or one will eat the other which in turn will eat the first one ... ove r and over.
Cool.

thanks everyone ill check out all my options this weekend thanks again
