EBC Contour rotors

[The Snowman]

I have a chance to get a brand new pair of EBC Contour rotors for Annalisa's CBR900RR.



I'm looking to replace the Galfer waves that I got off of fleaBay a couple years ago, because they're warped and cause a pulsing. I figured that since I have a new set of pads to go onto her bike over the winter, I may as well do everything.

Someone on one of the RR forums is selling a brand new set for $250, which is what a single rotor cost.

Anyone have any info on these? Good? Bad? Bueller?

I've got a couple for my GS500E. Seemed to work real well, the EX500 guys are reporting that those in combination with the new EPFA pads are providing excellent stopping power and unlike the prior EBC rotor/pad combo are pretty damn warp resistant. The buttons do not 'spin' like you'd expect, and that's intentional. You also can't really 'feel' the float in the rotor with your hands given how tight they run the buttons, but you can't argue with no warping or pulsing, right?

ANd for $250 for a brand new set, I just may go for it.

Since they're for Annalisa's bike, and she's not the type who feel every little detail while riding, they may be perfect.

Oh, and they're not the gold-centered rotors, they're the Pro-lite polished aluminum, so, she gets some bling factor.

Buy em.

I'd say they're better than stock. And the price is right.

I run regular EBC floating rotors, and go through more brake pads than any other EX guy (another goal of mine for 2010, less brake). I didn't warp mine? Probably just going too slow...

she'll never use all the braking power...

I hope not. Wouldn't want her to become an icy hot stunnah and perform stoppies.

Too slow, on the brakes longer with less force

- vs -

Faster, and on the brakes HARD for shorter durations.

I'm really hard on the brakes, don't you remember how I always passed you? The experts actually tell me I'm too hard on the brakes and should go easier, which I want to work on this year

So, other than in Photoshop, why aren't you an expert already?

because I'm new, and slow. and I suck. in fact, all I really have going for me is that I'm faster than you. really hard braking doesn't = fast you know...

[G21forme]

If they need to be replaced anyway I'd go for it.

[Kurlon]

Yeah, $250 for a PAIR is cheaper than retail on ONE rotor, if you have a reason to be shopping I can't see how you'd justify passing that up.

[The Snowman]

Thanks for all the input. I ended up grabbing them. He lives in NH, so they'll be here by this weekend.

I was getting worried about the pulsing. It was fine while I was riding the bike, but I wasn't so sure now that it's her ride.

[The Snowman]

BLING!

Half-priced, brandy-new rotors.

[csmutty]

You'll never use all that power.

[Jim]

congrats. make sure you properly brake them in with your pads.

[The Snowman]

I plan on it.

Wrong break you idiot.

[Jim]

what are you running for pads?

and i apologize Mr Spelling Bee Champion

it will be a new set of Galfer G1054 organic pads, thanks to Mr & Mrs Duncan.

are those buttons full floating?

looks like we both did some brake upgrades this winter.

*shows motorcycle parts ignorance* Not sure. If by full floating, you mean that the buttons can rotate in their slots and that they allows the rotor to move in and out, then yes, they are.

[Jim]

very good price then

[The Snowman]

very good price then

Best online price that I saw was $210, each.

They must be older models though, since they don't have the S-Drive button system.

SD Stands For Square Drive
All conventional floating brake rotors use a circular rivet to attach the rotor blade to the inner hub. The SD-SystemTM uses a square sided rivet with many advantages.

The theory behind SD-System
Under the heat of braking a rotor blade expands or shrinks in both its diameter and band width causing the inside of the rotor blade to shrink radially inwards towards the hub. With circular buttons, as the rotor shrinks, it will contact the inner button and cause the rotor to tighten and either be distorted sideways causing either brake pulsation or spongy brakes.

The SD-System of square sided buttons means that the rotor can expand inwards and outwards unrestrained and that perfect rotor functionality is retained at any speed or load. Not only does this extend the lifetime of the rotor and prevent distortion failures, it keeps the rotor blades perfectly true and flat throughout their life cycle and technically the only reason for a rotor to need replacement will be impact damage or over a VERY EXTENDED number of miles possible rotor wear limits being exceeded. This means that a rotor equipped with the EBC Brakes SD-System could last 5-10 times as long as a conventional rotor built with circular buttons.

A further advantage of the SD-System is that the drive forces under braking are transmitted over a LINE CONTACT on the square side of the button compared to the point contact of a circular button. Extended use with a circular button and its point contact will mean that the rotor could shake loose over a period of time in the drive direction. Slackness of the rotor blade relative to the inner hub is a major negative and can cause rotor “throw-out” and lead to severe vibrations at speed. The SD-System maintains close tolerances of the rotor in the drive direction over a far longer period thereby extending rotor life.
