Radial Brake Conversion

I'm interested in upgrading the stopping power on my Hayabusa. I'd like to do away with the six-pot calipers and change to four pot radials with an aftermarket master cylinder but I don't know what all is involved. I would think it would be possible to use the stock forks with different mounts for the calipers - but I really don't know.

You can just add steal braided brake lines for about $50 and you will feel a difference. Otherwise your probably gonna spend over $400 for aftermarket rotors and cal

thanks guy.. i am in need of the same fix.. the brakes on my 06 limited feel like couple of blocks of wood on the calipers... i will try the braided lines first.

Those are ths same brakes on the GSXR1000 and they really suck. If you want to go radial, you can replace the fork ends. But there are some good kits to replace what you got for a little less effort. You can get some brembo setup along with a new master cylinder and make a HUGE difference. The $50 brake lines will help a minor amount.

Yeah, I'm familiar with braided lines, and consider them a must have. I don't think that they will provide the stopping power that I'm looking for. I'm well aware of the price of full replacement stuff like Brembo calipers and master cylinder. The Brembos that aren't even monoblock are more than a grand.

So you just have to replace the fork ends to run the radials?

Have you tried different pads? Some EBC HH or Vesrah pads can make a large improvement.

Be patient, I put EBC's on one of my bikes and it took maybe 50 - 75 miles before they got good. When they got good they got really good.

The last pads I got were def. an improvement. They were some pads that Andy at Metric recommended, but I don't remember what they were. Pads and hoses can help alot, but I'm interested in serious stopping power. I guess I'm really asking what all is onvolved with switching to radials, fork ends, master cylinder, anything else?
I guess rotors too?

Change your pads and your lines, clean your rotors and put in some good brake fluid like Motul RBF.

You will notice a definite improvement.

As a rule of thumb, the more pistons you have in a caliper the better the stopping power of your brakes. Why would you want to "downgrade" your brakes to a four piston set up?

If you do not have braided lines, get them, they will improve your stopping power and will give you the best bag for your buck.

What will be involved in "downgrading" to four piston radials? Easy, an entire new front end to your motorcycle. Radials mount differently to front forks and will require a front suspension change. You may also have to switch out front wheels and rotors along with your suspension to get a good fit to your new custom front suspensions. Lets not forget the cost of going through your new front suspension to set it up for your current bike.

Things like this make the 1K Brembo kit start looking cheep, but hey, it's your bike, do what you want to with it.

You could keep the same rotors.
The easiest way to do it would be to swap in a GSXR front end.
You'd have to do some minor machine work as far as wheel spacers etc, and I'd recommend respringing / revalving it for the Busa, but it can be done.

Installing a radial master may be problematic from a fitment aspect when the bars are at full lock; the reservoir / master cylinder may contact the upper.

IMO you're not going to see as noticeable difference by doing that vs the steel line / pad / fluid upgrade.

The master cylinder can be swapped out for a standard one with a larger bore, which would give you more fluid pressure at the caliper.

My brother's GSXR1000, and dad's 750 both have four pot radials that are like night and day when compared to my six pots. Six pots were the 'next big thing' around 99-2000, but since then 4 pot/radials have been standard for performance applications.
Gigolo, my 6 pots are not radial, so herein might lie the difference that I'm talking about. If I could attain even a proximity to the stopping powered offered by the 1000's four pots, that would be a "downgrade" that I'd be willing to spend the cash on.

Hey man, just go see Patrick and let him hook you up. He obviously has your best interest in mind. If he wanted to make $$ he would have said, "Come see me and I'll get you the set-up you are talking about." But he didn't say that. His experience and customer service led him to tell you a solution that will save you money and meet your needs. I'm pretty skeptical of shops, mechanics, dealers, you name it. I've yet to see Patrick say something that wasn't just intelligent and honest advice in the other person’s best interest.

Oh yeah, one more thing. I don't work for him, with him, near him, I never even met him. But I do pay attention.

put a gixxer front end on it. you wont have to do no machining to wheel spacers or anything else. all the newer suzuki has the same measurements. well except for 05 06 07 1000 and 06 07 600 750 those wheels and discs are different but the axle and spacing is the same

Chris,
You're correct, if he wanted to bolt an entire front end, rim, rotors etc. out of a GSXR onto his bike he wouldn't need anything else.
I'd still recommend springing revalving it for a bike thats 25% heavier than a GSXR though.

What I was saying is if he wanted to keep his Busa front wheel & rotors, that the hub is wider than any of the GSXR radial series forks, so spacers would have to be made. (which is why we can't use those rims on our late model GSXR racebikes without different spacers! The Busa uses the same wheel as the SRAD. You were drinking last night weren't you?:laughing6 )

/ hijack on / BTW, thanks for the R1 / R6 stuff! Did you guys find a bike for next season yet? / hijack off /

The whole premise behind radial brakes is not more "clamping force" per se.
Clamping force is dictated by hydraulics.
Radial brakes claim to fame is in the way they are bolted onto the fork leg is more rigid, therefore transmitting more force to the brakes with less flex at extreme braking inputs.

Unless you are at racing speeds, you'd probably never notice.

IMO, if you were to ride 2 Busas that were identically prepped bikes, but the only difference was that one had radial brakes and the other had standard, you couldn't tell the difference.

The main reason your dads / brothers GSXR's stop a lot better than yours is not so much due to radial brakes, but because they are 100 lbs. or so lighter than your Busa.

Less mass = easier to stop, it's that simple.


My 2 cents, YMMV.

Agreed, If you want to stop faster, get a smaller bike.
