Singing rear brake disk

My rear brake disk (?) has been squealing on me lately when I back the 2014 Honda Forza 300 out of the garden shed.

I partially took the brake caliper off and had a good look at it. The pads are about half worn. It only makes a hideous sound when first backed out. It is fine for the rest of the day.

I decided to spray some soapy water on it today for some temporary lubricant. I backed it out with no sound what so ever.

I have been watching the air temperature lately looking for a rideable day with no ice.

Today I let it get up to 5 degrees C before I got the scooter out. My driveway still had a coating of ice on it but I hoped that by the time I got out to the road it would be ice free.

I live in the shadow of Chawathil Mountain or the place the sun don't shine in the winter. And I thought people were being rude to put it where the sun don't shine. Just means my house.

It also means I have ice longer. Spring will get here eventually.

I carefully rode out to Hunter Creek where the sun was shining and the road was ice free.

I had coffee at Popkum. I took the Lougheed Highway to Mission. Canadian Tire had trekking poles on sale so I bought new ones to replace my recently lost ones. I loose everything. I also get lost easily. That is one reason I sold my dual sport DR650.

I had a stroke many years ago. The potato chip fat in my neck shut off my brain for a few seconds. My Ford Ranger was spinning its tires on ice and then suddenly re-connected violently. The whiplash gave me brain damage.

On my way home I stopped at Harrison Hot Springs to try out the poles. First I got my Starbucks at the hotel. I set up the poles and trekked over to the hot springs. The tourists found the water HOT. I told them it was the volcanoes fault. They looked at me like I was an idiot.

We have several volcanoes close by. Mt Baker is 59 km from the Hot Springs. Geographically close. Mt Garibaldi is a little further at 107 km but it is all uphill. Mt Meager can be active sometimes and the Bridge River Cones are not that far away. Even Glacier Peak is only 141 km south of the Hot Springs. It's gonna blow!!!!!!!!!!! Which way is the wind blowing?

It was icy by the time I got back to Hope and had supper.

I need another Michelin CityGrip rear tire so I better order another one from Fort Nine in Montreal. About 11,000 km on the current one and counting. 96363 km all told at the last gas fill up today. 79 miles per Canadian Gallon today in the cold. I also need a haircut but it is too cold. Maybe in March.

I've gotten that sound through the years on different motorcycles I've had as well. . .. No big deal if checks for wear and warping come up zilch. Check the pads wear grooves too to see if they need replacement. I've gotten that faint squeal on front and rear disc brakes from time to time.

Occasionally I get it on my new Zuma from the rear disc brake for some reason while backing it in after a ride since it's turned significantly colder and been really windy this week. I still have been riding even though the daytime temps have been below freezing. I've still got less than 2K miles on it.

You can always check to see if the rotor looks bent/warped by spinning the wheel (motor off of course) for a quick observance. . .but a micrometer is the way to go. There are other methods as well.

Another thing you can check is if there is excessive heat build up on the rotors after riding a fairly short distance with little use of the brakes. That may indicate a sticking pad or something lodged.

Are your rotors groovy? The outer edges of the rotors will protrude compared to the center part of the rotors (mating surface of the pads) that will wear in over time. The outer edges have nothing interfacing with them so they maintain their original manufactured dimension.

I assume your 2014 has the disc brakes both front and rear. . .. :geek:

I wouldn't worry about it. My car does the same thing when it is cold and damp outside. Then the disk warms up and it is fine. Very few cars with disk brakes don't squeak when cold and damp. If the rotor isn't warped and the pads are fine, don't worry about it.
