Question Brake fluid change- weird sound

I have successfully changed the brake fluid on my 02 LT in the past several times, with thanks to John Z. for his DVD, and I believe I probably got too confident in myself and went too fast on the change this time.

After trying to bleed the front wheel circuit and having my Dad watch the handlebar reservoir as I cracked the bleed valve, I realized that the handlebar reservoir is not where you add for the front wheel but rather the rear reservoir. I believe I may have introduced air into the system. I did not confirm that the rear reservoir was bone dry before adding fluid, but if it wasn't, it was very close.

I haven't taken the bike out for a spin since I am waiting on buckets, but when I apply either the front or rear brake HARD, I hear a whining noise that goes down in pitch. I don't think I had heard that type of whine before. When I give a light touch to either brake, the servo spins fast and at its normal whine pitch.

No constant lights or abnormal warnings are on for the brakes.

My question is should I just wait to take it and ride, or should I try to bleed some part of the system in the thought that I may have air in it?

Thanks for your advice.

James

"Hard" it's ok I think,? mine does the same and another I bled last week as well. I am guessing it is the abs kicking in, light pressure only gives you servo assist not abs. if you have a good solid feel with the hand brake ign off, then you are good to go.

Thanks Linton. I checked the front lever with ignition off and the feel is good and firm with no spongy.

To be on the safe side get a long piece of tubing and run it from the front caliper (left side) back to the rear half of the reservoir. Open the bleed valve on the caliper and turn on the key and pump away as you watch for air in the tubing. That will get all of it out. make sure the reservoir does not run out.

Thanks John. I went to Lowes and got some tubing to use for this process.
