Pig of a rear brake, thar be squealin' boi!

[onearmedbandit]

Read an interview with a top MotoGP techie, who said ALL the worlds FASTEST racers use the rear brake. Now get this, by applying enough rear brake when entering a corner, combined with obvious front braking you lower the centre of gravity of the bike, allowing for higher corner speed. Now if you want to argue with someone in the know (how many here are involved with top-flight race teams??) be my guest, as for me I know when to shut-up and listen. He also claimed many riders choose to 'trail' the rear brake through a corner, helping to compose the bike under power changes, etc. (Yes, the article was about the use of rear brakes)

too soft a compound pad will cause squeal. Its the dust that builds up and causes a glaze on the pad surface. On many bikes their isnt sufficient air-flow over the calipers to clear the dust so it builds up.

Wooden brakes (no feel) are often caused by matching the wrong compound with the application (both usage and disc material). If you have carbon or stainless sintered, you probably wont get enough heat into them for the beggers to start gripping, so they just feel wooden and give the impression you have to haul on the lever.

Not just that, but they're also subject to building up road crap from the back tyre.
If the pad is glazed, you can sand it back with some sandpaper, and give it a clean with brake cleaner (clean the disk too while you're at it.)
The pads could well be just worn down - some of them are designed so the anti-rattle doofer (technical term) contacts the disk when the pads are worn to the limits and makes a god-awful squeal to alert the less maintenance-conscious to the fact that they're ferkt!

Jeez, WTF ...who rattled your cage??

I thought :spudwhat: there was a reasonable sort of discussion going on...but I'm wrong again.

However plainly you are an incontrovertible authority, indeed plainly no less an outright oracle about this matter, having once read an article by a MotoGP mechanic..... so I for one will in future refrain from any utterances that might conflict with your estimable wisdom

As a matter of interest, many of the top racers also slide their rear wheels in a controlled fashion...but that doesn't make it a good idea for lesser riders. My point, not that I expect you to grasp it, is that there are differing views about the use of the rear brake. I would not be so foolish as to tell someone with a different outlook to "shut up and listen" because fora such as these are intended for discussion, not unilateral (and arguably ill-informed) proclamation by one onanist.

Maybe you're disk is squealing like a peeg becoz theres one trapped in there. HAve you checked you haven't got one stuck in the works somewhere?

Or maybe it just needs some lubeing. Soak it in some grease from a pork chop.
mmmmmm.... porkchop.....

It doesn't matter how it happens - braking,engine braking or under power - but I prefer to have an unsettled rear end....if the rear tyre is under stress,the front isn't,you very seldom lose the front if the rear is fighting for traction.

[TwoSeven]

You cant really say that people should or shouldnt use the rear brake because it depends on the bike - some bikes have rears that work, some dont - and the capabilities of the rider.

Brakes are not just for stoping the bike, they are also for controlling stability, cornering technique and aiding in changes of direction as well as ultimate speed in the wet.

To say that you shouldnt use them or to leave a dud rear on a bike without trying to fix is in my mind is akin to chopping off a leg and wondering why you cant run very fast.

Right, first try actually reading a post before commenting on it, then you might not make yourself out to be an idiot.

1/ This is not my information, nor my wisdom, nor am I an 'incontrovertible authority', and for that matter I am not an oracle. See, if you read my post I was quoting a person who is no doubt an 'incontrovertible authority' on the matter. Nowhere did I claim that I had established this opinion. You sir, need to educate yourself to avoid making yourself look so ignorant in the future.

2/ The post was not suggesting this is a suitable techique for the road, new rider or experienced. While posting I thought I might need to clarify that point, but assumed that everyone here would see my post was in response to 'many racers don't use the back brake'. Proof again of your inability to comprehend the English language.

3/ Did I say he was a 'mechanic'? No I did not, wrong again. Please, please, learn to read properly.

Now I'm not trying to cause shit with you, but if you bring it I will let you know all about it. Thankyou and have a good day.

WELL.......... I race, and i use the rear brake..... but then again, im slow so dont have a clue..... however MR is fast and he also uses the rear brake..... but then who gives a fuck.... do what ever feels best for you.....

Anyway back to the original question...... Ant, what Two Seven said is another possiblitly, i had this problem on the RG but it was more of a groaning sound for me.... But i would go for the brake pad change mate Highly recommend SBS pads...

then you might not make yourself out to be an idiot.

*yawn*.....

Well thought out response there. I clarify my post, hoping to clear up any mis-understanding, and that's the best response you could think of. My point is proven.

Oh drat....there you are again!!!

I would like to engage you in a battle of wits but, as a certain politician said, I won't attack an unarmed man....

I could spend time rebutting your attempt at clarification point by illogical point, but I lack the interest, you would still fail to get it and I anyway don't see the need. Let your postings speak for themselves.

That's it from me. Attention span already all used up on this tedious little spat.

No please inform us all where I am wrong. I'm all ears, or in this instance, all eyes. And since when has this become a battle of wits? All I did was post something I have read, you slammed me for that, but won't give a reason or reasons why. So have you the balls my man, to back yourself? I'd love to hear from you, seems you have formed quite an opinion of me from one or two posts. However, I suspect you will go quiet on this, having nothing to back up your claims.

Fight fight fight fight .... just kidding .. Kiss and make up eh it's nearly Xmas!!!

[kerryg]

No please inform us all where I am wrong. .

Oh ...do I want to...ummm... alright.

1. Your first posting included these immortal words: "...if you want to argue with someone in the know (how many here are involved with top-flight race teams?) be my guest, as for me I know when to shut up and listen".
I could say many things about that, but the main ones are as follows:

a. it rules out that any differing view could have any validity, and tells those who see shades of grey where you see only black and white to "shut up and listen". It's at best damn impolite and at worst downright arrogant.
b. the basis of your authority in making this bald statement is ONE article you claim to have read. You have no other basis to support your sweeping and over-riding statement, you do not attribute your source, and you state 1 man's opinion as if it as a matter of unarguable fact. Which it is not (unarguable I mean). Of course it might well be true but YOUR saying so doesn't make it so. Hence I pointed out that you are acting as though you are some sort of oracle on this subject but don't appear to have much in the way of credentials (other than 1 article) to support that imagined status
c. there are lot of KB members who constructively, wittily and helpfully engage with others on this forum, and all power to them I say. It is not in the interests of sensible, reasoned useful discussion to take a totally dogmatic position and proclaim its correctness for all to hear, and most particularly when it is done in an insulting way to others trying to contribute to a discussion.. You are free to do it (it's a free country), but don't expect me to think it's OK or to withhold from expressing my displeasure


I have no more time now (5 o'clock on a Friday...I'm off) but I will continue on Monday
