Brakko Combined Wheel Brake System

Taking a new perspective on motorcycle brake design is Brakko with its Combined Wheel Brake (CWB) system. Unlike a traditional system, a CWB system puts the brake disc in the centerline of the wheel rim, which allows for the braking force to be transmitted as much as possible to the wheel rim, instead of to the hub, spokes, and brake disc carriers.

CWB boasts having a “true” radial mounting of the brake calipers, as well as lowering the overall weight of the brake assembly. Also, CWB systems allow for greater cooling of the brake discs.

Brakko has designed their CWB system to allow for multiple caliper positions, which can accommodate virtually an two-wheeled application. Additionally, Brakko’s design allows for quick disassembly of the entire front-wheel from the bike with the aid of their custom fork bottoms and quick-swap brake line connectors. Brake pad maintenance looks relatively, whereas getting to the disc itself could pose and issue, especially with spoked rims.

    That is a ripoff of Buell brakes. I’m disappointed in this publication for making a big deal out of a product already done in EARLY 2002

  4. Jenny Gun says:

    Rip-off? I dunno about that. These, like the one’s on the Buell, are a single-disc perimeter style brake. However, Buell’s design is mounted on the side, like a conventional braking system, whereas these are directly centerline with the tire. Also the caliper mounting is completely different not to mention the disc is an actual stressed member of the wheel.

    It would be a bitch to clean, I’m betting.

    Buell’s design put the disk on the side of the rim for reasons of cooling… I would like to see the heat coming of those after a few hot laps. A step back from the Buell design I think.

  8. Cliff says:

    Huh. Looks like they took the Buell ZTL system and then made it unecessarily complicated. I’d like to see a weight-saving comparison between the two.

  9. Cliff says:

    Dave makes a great point about the heat as well… those pads are virtually shielded. Certainly a step up from conventional brakes, but seems to me like Buell still had the better design. Sometimes a thing can be ~too~ high tech for its own good.

  10. 4Cammer says:

    Nice, looks great, but I see the same basic idea on my Buell XB9R every time I ride her.

    And no, Erik Buell did not do this to take care of any heat issues. Weight is the enemy, and that is why it was done.

  11. Blake says:

    Neat looking computer generated vaporware variation on the Buell ZTL system. Simple questions screaming for answers:

    1. How much does it weigh compared to the Buell ZTL wheel/brake/fork lower?
    2. How does it perform under severe stress, meaning high heat, aggressive braking.

    The Buell Forum at http://www.BadWeatherBikers.com has taken notice. See comments there at…

  12. Philly says:

    What happens when heat causes the rotor to expand? I don’t see much room for the disc to expand, and I sure wouldn’t want to try and bleed them if the brake lines route through the hub.
    Looks like it’s just an end-around to keep from violating Buell’s patents?

  13. Al Staples says:

    Seems sad to me that Erik Buell, probably the smartest man in the motorcycling industry today didn’t get this kind of attention when he brought this type (and better) of braking to production motorcycles several years ago.

  14. CBRR1000_i'm_ignorant_like_a_boss says:

    yeah, but have you guys seen what honda is doing with their underslung exhaust?

    man, those guys …..oh, wait. ummm…. never mind.

  15. This system looks great. Our company holds the patents for U.S distribution of Internal brake wheels. We came up with this system 6 years ago. As for the buell bikes they never had true internal brakes.( calipers behind both wheel faces) The Buell calipers were externally mounted conventionally on the lower fork leg. We initially designed a setup similar to this one. However our current system is much cheaper to manufacture and allows the wheels to be tailored to any bike with ease. and cost is similar to a complete set of billet Pm’s or extreme machine etc. $5,500 to 6,500 dealer cost complete. Brakes, wheels any finish, rotors etc. we make them in 18″ to 26″ sizes unlimited width. Check out glenndynedesign.com The gunmetal and black set on the website was a prototype set. The production sets use all DOT brake lines and fittings. We are just now finished with our rotary forging dies for all Wheel faces ranging in sizes 18″ to 26″ we are now in full production designing different styles and setting up dealers.

  16. Jenny Gun says:

    No 17″ wheels Aaron? It’s gonna be hard to win over the sportbike crowd without a 17″/16.5″ option

  17. Jenny,

    We have just been producing 18″ and up because of demand in the custom industry. With harleys etc. We would consider building the rotary forging dies for the 17″ wheel faces if costomers want them. We are just now launching the wheels for production bikes at the CINCI dealer expo. Feb 2010. thanks for your question.

  18. Andre says:

    I guess that this “centered” system, besides heating problems, still transfers torsional load to the hub, where calipers seems to be attached, requiring wheels to have more mass. Am I wrong, or this would “throw away” the real advantage of ZTL system, e.g, reducing unsprung wieght?

  19. Del says:

    I think beating up on the design is pointless, the system depicted here could offer substantial weight saving in that the wheel spokes can be a lot lighter due to the fact the braking forces are applied to the rim not the hub.

    The calipers can’t be attached to the hub as they would be turning with the wheel, if they were you would have no braking.

    Its not entirely clear in the video but the calipers must be anchored to the spindle in some way, which would then have to transfer its loading through to the fork legs.

    I think the design is unique and interesting, i’ll be looking out for this to see how it develops.
