What could be causing the Loud brake noises?!?

[totalcomfort]

Just got a 14 Rts for the wife, has about 25k on it. Maintenance history was good from previous owner but have not had a chance to go thru the bike yet. While using the brakes at slower speeds they are very loud making a howling type sound. I checked the rotors and they seem fine and brake pads appear fine. Could the pads have been replaced with aftermarket pads causing the noise? Brakes work great and everything seems fine when riding. Thanks for any help.

I don't really think a/mkt pads will be the cause of that noise.... :dontknow:

The OE Brake Pads & Discs on Spyders are pretty much renowned for making loud braking noises, especially at low speeds; and many swap to EBC a/mkt pads to reduce the noise, which is usually a very effective solution, especially if the swap includes the addition of anti-squeal compound on the back of the new pads! :thumbup:

It isn't really an issue tho, the Brembo Brakes on the 2013 & on Spyders are really very good, even if they do make a noise. If the noise really bugs you and you have a sensitive enough foot, you can learn to apply your brakes in a way that'll minimise the noise somewhat; or you can just learn to live with it & appreciate it for what it is - the noise is really just letting the world know that your brakes are very efficiently converting rotational energy into heat & noise. hyea:

There again, if you truly can't live with it & you haven't been able to develop the knack of using your brakes in a way to minimise the noise, you can always try adding anti-squeal to the back of the pads when next you can take them out; you can swap the OE Pads for EBC pads with anti-squeal compound added on the back of them during installation; or you could swap out both the Pads AND the Discs for EBC replacements (with anti-squeal as appropriate) - they'll work at least a bit better, generally last longer, and when fitted properly with anti-squeal applied, are usually a whole lot quieter too! :thumbup:

" appear fine " ????? ....how closely have you looked ...... good luck .... Mike :thumbup:

And when you check the pads be sure to look at both the inside and outside pad on each wheel. Seems they have a habit of not wearing out evenly.

I replaced My O.e.m. brakepads, at less then 10.000 km's, there were metal on metal, I replaced them with ebc rotors, and pads, and they work better then the original stuff. and they sure seem to last longer, and quieter.
As noted in previous post, my pads did not wear evenly. I think I must have had a bad batch...
use antisqueeze, and you'll be a happy camper

If you have taken your pads out, did you notice if the back of the pads were coated with any kind of, ( I call brake butter), It's a produce that you can get at the auto parts store that you coat the back side of the pad to get rid of that pad chatter, or squeal! I got a set of pads from Ron a few years back and in his instructions, he said to use it, I thought I don't need that crap, put them together and guess what, I did and had to redo it over again!! So, if it was me I would take the brake pads out and give everything a good cleaning and get yourself some of that paste and put them back together and see what you get!! Good luck!!

If you want to decrease the noise of the brakes a lot, file the corners of the brake pads like the picture so that the brake dust comes out.

All good Tips. The beveled pads are needed to get a noiseless operation. Most of the better brands of pads have this beveled edge. I only install beveled pads.
Also be sure to use 'special pad grease'. Most auto parts store should have it.

My Tip: Install beveled pads. ......:yes:

 

[totalcomfort]

Thanks for all the help, I am going to dig in before riding season and get all the maintenance stuff checked and all the fluids changed. New to the spyder bikes but work on my 03 Goldwing and several other bikes. I have ordered a factory service manual, but will have a lot to learn.

The noise or squealing is caused by vibration. It is not the pad rubbing the rotor. Beveling the pads helps and using the anti-squeal "brake butter" (I like that) will dampen the vibration and eliminate or greatly reduce the noise. Brembo brakes in general, not just the ones on the Spyder, seem to be prone to this. A shot of compressed air to clear out the dust and dirt wouldn't hurt once and awhile. The rear caliper gets especially dirty since it catches all the crap thrown up and also lives in an environment that doesn't get much cleaning/cooling air. The extra heat and dirt also contribute to rear pad wear.

I Guys !!!

Over the years I have looked at a lot of information on brakes that are squeaky, what I have found is since asbestos is banned in the material mix, the new materials are too hard, and if have little to have Ceramic coolers sound much better, they squeal less and easier to clean the wheels and mags.

There are several things you can do to reduce squealing. Which, as mentioned, is a high frequency vibration. Pictures are meant to be representative of the advised action only. They are not Spyder or Ryker pad sets.

Bevel the leading edge with a file. I don't recommend filing the trailing edge. You don't back up that much and filing both leading and trailing edges will reduce pad contact more than necessary. Pads come with both edges beveled because they don't know which way you are going to install them and they want to be sure the leading edge is tapered. If you're doing the install yourself. You can end up with a better job by just doing the leading edge.


Cut 1 or 2 lines in the pads. This removes very little material. This squeegees the rotor helping it to stay free of brake dust. Another reason for squealing. It will also help to shed water. But this is not really a problem with disk brakes. Personally, I prefer 2 diagonal lines cut. But I cannot say that this is any better than the other approaches. I use a hack saw. Do not cut all the way through the pad. Leave a little meat at the bottom of the pad.


Coat the back of the pad with a thick layer of Anti-Squeal gel. This gel absorbs vibration. Vibration builds on itself. If you can prevent it in the first place, it should solve your squeal issues. You want to put it on fairly thick and let it dry for a bit. Giving it time to set up before installiation.


Clean and then apply Anti-Seize on sliding parts. This will help the pads to move freely and wear evenly. Use a very thin layer. This is not a product where a little is good and more is better. This is a case of a little is good and more is not good.


Once installed. I recommend 'Bedding In' your new pad set. This requires that you go from 60 mph to 20 mph as quickly as possible. This needs to be done at least 3 times in quick succession. Do not come to a complete stop. You should start smelling hot brakes. This means that the brakes are getting hot enough to cure the resin which is used to bind the friction material. This curing process prepares the brakes and will not only make them stop better. But will also reduce squealing. This can also be tried as a cure for squealing brakes.

Be sure to do this on a clean and dry stretch of roadway, free of traffic and long enough to accomplish the task without having to stop.

Once you've completed these 3 consecutive hard stops. Ride at least 5 minutes with little or no braking to let the brake components cool evenly. If you stop with hot brakes. The very hot pads are clamping on a small portion of a very hot rotor. Which can cause warpage. Riding for 5 minutes with little or no breaking will prevent this.

Like Mike says! "Good Luck!"

:agree: with Ron's advice especially the BEDDIND-IN process .... I buy my EBC pads from Ron :thumbup::clap: ..and IMHO they / He are the best ..... I tried to cut a line using a thin ROWTER (?) cutting tool .... BAD idea , the sintered pads ruined that tool very quickly ..... not deterred, I then usd a very thin ( 1mm ) cutting wheel on my angle grinder .... I clamped a piece of wood ( as a spacer ) to the pad and that worked .... I only made one Diagonal cut on each pad ..... Mike :thumbup:

 

[EdMat]

Cut off wheel on a Dremel tool works real good for the cuts

 

[Little Blue]

Hack Saw

:chat: YES, a lot of good Tips.
I have used a hack saw and it was very doable for me.
If you don't know what you are doing, then let the 'Pros do it'.

Brakes are a Safety Issue. ...... : )

Thanks Ron, I knew you would jump in, great pic's and good advice, worked for me!!!:2thumbs:

 

[mecsw500]

Please wear a mask when cutting up brake pads. Cleanup with a HEPA filter vacuum or wash everything down. No, they won't give you Covid, but...
They can contain silicates, copper fibers, toxic metals and lots of other nasty things to breath in. No longer asbestos, but generating fine dust from all the materials in different types of pads such as metallic or ceramic is not something you want to inhale.
Good idea to wash your hands and launder your clothes after cutting them up. Reading the materials data sheet for them shows what's in some of these things.
You mileage may vary of course.

If the squealing just started, be sure the brakes are clean. I was on a gravel road in Colorado and my brakes were so loud I thought I would have to get them replaced before I continued my trip. Based on advice from this forum, I gave my bike and brakes a good cleaning and the noise stopped. Never did have to replace my brakes.
