paranoid......squeak! - Page 2 - SV650.org

my guess is it'll be the brake pads just touching the disc. That in itself isn't anything to worry about, it's normal for a slight touch, but it shouldn't really squeak.

Ideally you should take the pads out and put just a very slight smear of copper grease on the backs where the stainless steel "anti-squeal shims" are. Be very sparing, just a spot on your finger and dab it over the area works well.

The most important thing while doing this is to grease the pad retaining pin, as your bike is so low mileage it should still be fine but they DO corrode in. The fronts need doing too. A few minutes spent now will save you grief in the future!

They have a little retaining R-clip to hold them in.

Get the manuals if you haven't already

...and I agree with Ben 21Quest to check wheel alignment (don't rely on the marks on the swingarm, they are just a guide). Although wheel alignment doesn't in theory affect the caliper alignment directly, I have found with mine that it definitely does affect how the pads brush the disc while the brake is off.

Best way to do wheel alignment is with string held tight. Tie it to the rear of the back wheel, go up to the front wheel and pull it tight and hold it so it's just touching the front of the rear tyre. Set front wheel parallel to string and measure distance from string to tyre (rear tyre is wider than front so there's a gap). Repeat it on the other side and the distances "should" be the same.

If you need to alter the wheel alignment, make sure you keep enough slack in the chain, at least 30mm mid-span on the bottom run or so you can easily hold 2 links against the rubbing strip on the underside of the swingard at the front. Better too slack than too tight.

while were on the subject of bearings . . . anyone know the ABEC rating of motorcycle bearings ?

I did a search and saw mentions of ABEC7, but i thought it only went to 5.

Hi Jenni,

Just to ad on the WD40 front. DON'T use it on the axles of your bike, it'll break down and wash out any remaining grease from the bearings without leaving anything of real substance behind and then you're in trouble. I did the same in error on my mountain bike thinking that I was doing good.

Hope you find the problem soon.
