I checked the front pads on my M2 because I'm getting a squeaking sound. The pads have less than 3,000 miles on them and have plenty of pad left. What seemed odd though was the fact that I can wiggle them with my finger. Is this normal?

Second I just changed the rear pads and they where down to nothing. The rear roater is grooved pretty heavily on both sides. Should I replace it or can I have it machined?

I would not be concerned that you can wiggle the pads slightly as long as they are functioning properly when you apply the brakes.

Are there any other symptoms such as pulsing, etc. Have you tried brake cleaner? What is the condition of the rotors? The minimum allowable rotor thickness for both front and rear rotors is .18 in or 4.6 mm.('99 M2)

If the rear disk is grooved, I doubt there is enough material to machine it. I would replace it.

It sounds like the rear brake is getting used a lot. It is not really designed to be the primary "stopper"(note the smaller rotor, pads,and caliper with fewer pistons.

If you just bought the bike and know all this please disregard. If you are the individual that used up the rear pads, you are missing out on all the stopping power the front brake is capable of.

Please check out any of the sportbike riding "how to" books for tips on braking.

There are also some threads on the badweb on the same topic that make for some good reading.

Good luck on fixing the squeak.

Squeak found. It was the wind shield. I'm going to buy a couple rubber mounted nuts for it. I removed the front pads and then remounted them. They are nice and snug with no wiggle now. The front roater is in excellent shape.

As far as the rear roater I've had the bike since October and put about 2500 miles on it. When purchased the rear pads were low, but I only recently replaced them which were down to metal. The grooves are more than likely from that.

Jimmy:

You may already have the answer and just need to click your Ruby Red Buell slippers together.

The below photo shows the "Well Nuts" (perhaps one of the most optimistic names for a part) that are used to attach various Buell body parts.

Note that they have a "shoulder" on the side that gets pointed toward the sun. Sometimes . . . this shoulder gets on the inside, rather than the outside, of the inner or the two parts which are being attached and then fails to perform it's intended purpose.

In a perfect world when you are attaching two Buell body parts the "stacking" order is:

  • Well Nut Body
  • Inner Body Part
  • Well Nut Rubber Flange
  • Outer Body Part
  • Nylon Washer
  • Screw Head


Clear as mud I suppose. . . but look and see if the flange on the Well Nut has slipped inside the inner body part.

Many of us have learned, with lots of cussing, to gently extricate the flange when it pops in. That's how I learned to cuss in 1988.

Just something to check.

The well nuts did not fix it. I had a buddy come over with much more knowledge than I have and we found it in about 20 minutes. A few squirts of WD40 down the spedo cable and the squeak is gone.
