RE: Squealing Front Brakes Just Before Complete Stop - iamheero_imp - 02-24-2019

Mine does this and I think it may be related to my ABS malfunction issues (that I'm still having). I've tried CRC Brake quiet grease on the pads, totally cleaning the calipers and pads, replaced all brake fluid (and clutch fluid while I was at it), still moans/hums as Caruzin described just before complete stop, and just like the OP, it only happens when I'm braking harder. If I brake very slowly/lightly it doesn't really happen, but that's not always possible in LA. I ordered new pads to come this week, hoping it's not rotors on a bike with 3,000 miles (though it's happened since I bought it at 1,100 miles)!

Anyone have any ideas? OP, did you ever solve this?

it could mean you just don't ride it enough.

My Canadian 2017 CB1100CAH (EX model in U.S.) has pretty amazing brakes for stopping capability but the fronts begin to squeal/howl just before coming to a complete stop. There is no noise at speeds above 10 mph. Also happens when reversing out of my driveway at low speeds.

The noise is somewhat akin to a Wet Finger rubbing on a Crystal Glass with an almost Bell Like character. It's annoying and embarrassing! Interestingly, if I tap either front rotor when off the bike, it's pretty much just a dull thud with no ringing quality.

Was wondering if this is a common issue and if anyone has found a fix for the problem?

Thanks,

My 2017 EX does exactly the same thing. I can't help but think that in the 50 years since the CB750 in 1969, Honda would have learned to engineer brakes that don't do this. I keep trying to convince myself just to live with it, since the braking performance is really good. My rear brake is functioning normally, except that I have noticed that it takes a very long time to return to normal after I wash the bike. It surely is taking longer than it would take just to clear any water off the rear brake disc. Perhaps the OEM rear pad material actually soaks up moisture and needs to build real heat to dry out? I don't know, but after 50 years of riding and literally dozens of bikes, this is something I have not seen before. At least the noisy front brakes work fine, even when wet.

I similarly wondered regarding Honda engineering. I convinced myself that it could be an issue of materials cost savings. I do not recall, but maybe a Forum member who exchanged the discs and pads out for aftermarket do not experience this braking behaviour.

I have read many squeaking brake posts. I am wondering why some are having this issue while others do not on the exact same year and model. My brakes are perfect. My only suggestions would be to remove all parts, clean and buff with a fine wire brush. Clean spotless with brake cleaner. Reassemble with anti squeal on all surfaces, even in between the heat shields. Let it sit overnight before riding. Report back.

I would not spray brake cleaner on pads friction surface + would deglaze rotors and pads surface with grid 40 sand paper & blow away/wipe off the dust**
** assuming OEM is used

I would not spray brake cleaner on pads friction surface I have 45 years experience working on bikes and have been a dealer service bench tech for Yamaha and Honda shops in my local area. I have worked with and for some of the best in the business. Brake cleaner spray is for cleaning all brake components, and l have used it hundreds of times to cure many brake problems associated with build up of dirt and deposits. Deglazing of the pad and rotor surfaces with the wire brush after cleaning restores them to like new performance.

That is fine, I do not question this at all Smile
I just said what I would do.


RE: Squealing Front Brakes Just Before Complete Stop - GoldOxide_imp - 02-28-2019

Just to be thorough, are both front and rear brakes squealing? Is the offending disc(s) still true (i.e. not warped in the slightest?).

Most of the ones I've read have to do with the '17 EX front brakes. That's the only one I know of that has owners complaining of a pervasive squealing problem.
