Trying to stop rear brake squeal

[oldgoat]

I have had rear brake squeal since the Spyder was new. The final straw was last week when I pulled in to gas up & the attendant came out & asked if the bike was OK as she could hear the noise as I braked to enter the service station.

I know that generation 3 Can-Am rear brake pads are supposed to cure it, but I have lots of wear left in my original ones.

Removed the caliper & then the pads & pins. Cleaned them up & chamfered the pads at the front & rear edges. Put a large fine file over the braking surface of the pads as well just to slightly roughen them.

Bought some thick synthetic grease type product in a small tube that is for quieting disc pads & put a little on the back of the pads where the caliper /caliper piston contacts them & a little on the caliper pins. Put it all back together - got none on the braking surface of the pads or on the rotor.

For the last 2 rides (175 miles each) I have had no rear brake squeal at all & the braking seems as good as it has always been.

Wonder how long the piggy squeal will stay away?

I changed to BajaRon rear brake pads and rotor. That stopped the brake squeal.

Untill....

untill the brake dust build back up. Washing them or compressed air will clean them up. Have heard that simple green works well just test brakes well after..:thumbup:

But that was an expensive fix.

 

[Bob Denman]

Glad to hear that your fix was able to do the trick! :clap: :thumbup:
Now you'll only be hearing the squeals and laughter from your passengers! :2thumbs:

Squeal: If you end up riding in the rain and get dust or glop on the brake pads, the squeal will come back for a little while. On mine, I notice it mostly when I back up the first time after a ride in the rain.

In 4 riding seasons on the Spyder, I have yet to be out in the rain.

However, I'm sure that will come to an end when my brother & I go to PA in July.

Whats bringing you down here in July?

Brake squeal rinse

Rinse out your calipers and rotors really well with a strong blast from your garden hose. It works, and will last for a few rides. j m h o .

Here are some 'Anti-Squeal' suggestions.

Put anti-squeal gel on the back of the pads (as you did). You want to cover the entire rear of the pad with a THICK layer of this stuff. Squeal is a harmonic vibration. Once it gets going it builds on itself as the vibration creates more vibration and the squeal gets worse. I use CRC but there are other good products out there.

You want a think layer over as much of the pad as you can get because this gel woks to dampen the vibration. So you want as much dampening action as possible. Less gel, less dampening. This is one of those times when a little works, but a lot works better.

Take a piece of 300~400 grit emory cloth and push it against the rotor where the pads run while you spin the wheel. This will remove the buildup of brake pad materiel embedded in the rotor giving you a fresh, metal surface.

Lightly sanding the face of the pad can help. But this requires removing the caliper which is more work than I want to do every time I get a squeak (which, by the way, I don't get any longer).

Beveling the front of the pad helps with going forward. Beveling the rear of the pad will help in reverse.

3 or 4 hard braking events in sequence can sometimes give temporary relief. This works pretty well when on a trip where you don't have time or the ability to do anything else.

Compressed air or a soap and water wash of the system can give temporary relief.

There are also spray quieters out there that will give temporary relief.

The 2008~2012 braking system was of poor design and quality. Squeaks are designed in. The current Brembo braking system used is light-years better and also afford the owner a much better aftermarket selection of pads.

The best approach is, when your pads wear out switch to a better quality pad and do the CRC Brake Quiet (or similar). This will not only improve the stopping power and extend the service interval of your brake pads, it is the best way to cure your brake noise issues as well.

The crc red goop works great. I used it when I first got the spyder, as the squeal was unbearable, and embarrassing. It lasted a long time. I'll re-apply on new pads when the time comes. Until then, I'll rinse them out every couple of weeks.:thumbup:

I happen to like your state & it's not too far from Montreal.

Going to the Grand Canyon on route 6
The painted barns tour not far from Reading
Coal country around Scranton

7 riding days.

Thanks for your 2 replies. I'll rinse them well next time I wash the Spyder.

I'll also do the CRC thing next winter.

Squeal Stop!

I applied per instructions, a product from CRC Disc Brake Quiet from NAPA Auto Parts, works great on the :f_spider: and all of our cage vehicles. A 4 oz. bottle looks like a lifetime supply. Absolutely quieted the built-in Back-up Alarm, now no more comments from the onlookers.:yes:

Off to Lake Placid tomorrow, will pick some up at the Napa in Plattsburg

Lots of great riding in Pa. Wellsboro area and south. 44,144 and 120 are great roads. If you can grab 414 off of 44 that is a great ride over to 220. Take 220 south to 87 east or try 187 in that area. Some of my favorite riding roads in Pa.

The Nicholson Viaduct.

Lots of covered bridges too.

 

[vrider]

I too have break squeal which is very loud and people look. Mine is coming from the front and back brakes, did this from day one as well.

Thanks, I'll look into them.

Ahh it is a beautiful state we have a bike rally in Erie, PA July 15th-18th was wondering if you might be heading to that.
