Hi All,
New to this site , so welcome from the UK.
Collected my GSXR 750 last month ( 2years old) and Love it.
Mature rider, well 39, missus still calls me a big kid!!
Anyway on my way to World Superbikes at Silverstone last week cruising on Motorway at around a Ton, i felt the back end squirm a little, you know that feeling when you have a puncture, anyway, slowing down the arse end was starting to feel uncontrollable, Told the missus to get into crash position - then told her too loose as she was crushing my ribs, finally came to a stop, jumped off bike, checked Tyre and nothing !! Tyre fine ! strange i thought, checked chain sprocket, etc, nothing wrong ? http://www.gixxer.com/forums/images/graemlins/dunno.gifBack on the bike rode off, yet still this uneasy arse end feeling, got off the Motorway checked everything, then noticed excessive brake dust around Tyre, touching the disk , it was hot and i hardly use the dam thing 75/25 on the front brake.
O.K here's my question, yes it sounds like the brake calliper sticking causing the pads to catch the disc, but can anyone tell me how this has been caused and is it a common problem ? I have 3 months parts and Labour and i dont want to be fobbed off.
Thanks Guys - See you in Assen http://www.gixxer.com/forums/images/graemlins/wink.gif

Alignment issue is my guess. It that's not it check the rear wheel spacers. I use to just tighten the axel bolt rather lightly and my big spacer on the sprocket side was worn excessively. I also had similar feeling of having a flat tire.

The only other thing might just be the fact you had the woman on it and your settings may not have agreed.

could also be swingarm or rearweel bearings, like philbie says above, itīs probable alignment issue that can be caused by spacers or bearings in your rear end.. (on the bike that is!!) http://www.gixxer.com/forums/images/graemlins/wink.gif
Good luck!

Silicone brake fluid will absorb water. Silicone is what is used to attract and absorb water just like in those little silicone packets to keep things fresh. When the brake fluid sits in an already opened can or in a vehicle that doesn't get used you have a good possibility of absorbing water. It wont show up as obvious water pooling unless it's drastic) but will be a moisture content before it gets overly obvious. Water or somebody used a transmission fluid type for brake fluid. Maybe even a funnel with lots of transfluid on it could cause impuritys in the lines. Water being absorbed or foriegn fluid is just a possibiliy. What the moisture can do is expand and cause the brakes to apply themselves. Normal brake fluid does not expand with heat. If the vehicles are regularly used the heat getting to silicone fluids will keep the moisture from building up. It wont cost too much to flush the system. Watch for rust. If some comes out I'd change the calipers with pistons if iron and posibly anything else that might of rusted since no mater what you do the rust will still be holding water. Good luck and I hope it's a simple fix like an adjustment.
