If I haven't used the rear brake for awhile on a ride and then use it I often get this horrendous loud howling and then some squealing/screeching. Seems fine other than the noise, changed stock worn pads at 5000 miles for EBC 460HH and have had the noise with both. Still have stock exhaust and wonder is the heat from that is involved. Any ideas? | ||

have you tried to brake hard a few times to scrub the pads? | ||
| Duphuckincati |
Yeah, try that often. No noticeable help. | ||

Be careful with just pounding on the brake pedal...! I was doing a quick check of things the other day and found the rear brake pedal on my CR wasn't moving by hand...! So rather than pound on it, I took it apart and found the piston frozen. But luckily, I found that just a small area outside of the bottom o-ring was bad. A quick cleanup and all is well.....AND...I didn't score up and ruin the cylinder doing it. As I said, be careful. Mike | ||

I've had the caliper replaced once and then the rotor, master cylinder and caliper together for that. I think it smoked a new set of pads within 100 miles and had the rotor looking pretty purple. I guess I had a bad master cylinder (sticking) and it didn't take long to do damage. I rarely use the rear brake, mostly for sitting on hills or at stops. | ||

I had the same problems with the stock exhaust. Soot from the exhaust is what I blamed for the noise. I have changed the exhaust and the problem has gone away. | ||
| Duphuckincati |
That's (Eddie) what I was wondering. I've got a Keda on order so I'll see then. Thanks. | ||

Could also be a worn, bent, loose metal clip too. My pads started doing that and I noticed that they also rattle about when full open. My clips are shot. | ||

Is it every time you use the brakes or just usually at the beginning of the ride? Moisture on the rotor will cause it to squeal a bit till it gets worn off. This will happen even with an aftermarket exhaust, but not as often. | ||
| Duphuckincati |
Not every time, and at any time in a ride it may happen. Not a moisture issue, I'm in a dry climate. And I'm about to pull the wheel for a new tire so I'll check the clips and such too. Thanks for the input. | ||

On the very first use of my rear brake, after the bike has sat overnight, it makes a squealing sound. After that, the squealing goes away completely and the rear brakes work like normal--weak. As long as it works I'm okay with it. | ||

Not every time, and at any time in a ride it may happen. Not a moisture issue It could still be a moisture issue - the stock pipe directs it's output onto the rear rotor and there is a fair bit of moisture coming out of the pipe at various times. Take a quick ride on the bike w/o using the rear brake then stop and wipe your finger over the rear rotor (check it's not hot first LOL).. if it comes up damp then you'll know.. I had the issue witht he stock pip but not had the same since installing the Barker 5000 miles ago | ||

these help alot with the exhaust gas's moving them away from the rear brake http://www.aph-performance-engineering.com/buell_1 125_exhaust_ans_buell_xb_exhaust.html | ||

I got the E.B.R. race rotor and it squeaks when it's wet, so it may be a moisture issue like others suggest. | ||

After having both the rear caliper suffer from seizing pistons and similar problems with the rear master cylinder I changed to a Brembo goldline rear caliper which needed no more than 1.5mm shims to get it right on the disc centreline and also fitted a Brembo rear master cylinder which was a direct replacement with no mods whatsoever. Far higher quality than OEM and cheaper too here in the UK - | ||

mine does it once in awhile cause I never really use it.no biggie | ||

My local HD tech said the loud rear brake howling is common on Buells, related to the rear disc and pads caking up with soot. He said to shoot it with some brake cleaner regularly. --That's my 2 cents. Dirty-john, PM sent about brembo upgrades. -Kevin | ||

Mine also went away after putting my Barker exhaust on. -Tutt | ||

Dirty, I'd be curious what model you ordered and how it all worked out, too. The OEM rear brake caliper is kinda heavy, and ain't all that great, anyway. Plus, the hanger pins wear out after a while and you have to replace the unit, even if you don't use it at all. Something better, but primary lighter, wouldn't bother me at all! | ||

To all, I will take some photos this weekend when I am home (I work in London but live in Chester UK) and upload to the forum next week together with whatever part numbers I have. All the part numbers for the Brembo gear are at home, from memory the Brembo caliper was a little lighter than OEM as well. Kevin pm responded to. Just to clarify, the OEM silencer was removed from new and the bike had a Remus can fitted which was quickly dumped for an HPE race can, I am saving up for the full Buell race exhaust at the moment therefore my OEM rear brake caliper was never subjected to the the crap coming out of the OEM silencer on cold start up or roasted with hot exhaust gas when the engine was up to operating temperatures (Message edited by Dirty_john on May 05, 2011) (Message edited by Dirty_john on May 05, 2011) | ||

even in a dry climate you will have moisture issues on the rear rotor with the stock exhaust because of the outlets. through combustion for every liter of gasoline you burn you will produce about a liter of water in vapor form. | ||

I still say it could be a worn wire spring/clip. You can only get them with the OEM pads. After a few EBC pads the little wire is ready for replacement. | ||

I'm a bit late on this, but I have a howl and it vibrate's the hell out of the bike. I can feel it in my hands. So loud my friend riding besides me said, what the F was that?! I didn't have the stock pipe on too long, then went to the HPE race pipe. Then it started happened about two months later. It still happens after one year. | ||

I just had problem on my CR, checked brake by pressing on rear brake pedal. The brake is locked, I tried to bleed the caliper to get it to free up, nothing doing, still locked solid. How "easy" is it to rebuild, not sure if I should just take it in for "warranty repair" or not deal with the hassle and do it myself. | ||
| Dirty_john |
DualBuells - the rubbish OEM caliper is not rebuildable - get the Brembo Goldline caliper, it is the same as fitted as OEM to some Ducatis, far higher build quality, lighter and here in the UK cheaper - it is also rebuildable so gets my vote. Had to stay in London this weekend so no photos yet. (Message edited by Dirty_john on May 17, 2011) | ||

Dirty_John - since you've changed both (mc & caliper) do you have a part number for them, I didn't see it in your post. thanks | ||

What model Brembo goldline fits? |
