Well after all the talk of braking systems and what can and cannot be used, I've decide to go off the wall. I'm picking up a COMPLETE brake system from a 2003 Suzuki GSXR600 from my friend for $75. 4 piston front calipers and dual piston rear. Whats everyones thoughts on this? Is it overkill? Most definitely! The first question has been answered.


Also another project thats coming up is my carbon fiber dash. But thats not crazy at all.

will those brakes even bolt up? and another thing is that how many pistons dont really have anything to do with breaking performance. all that really matters is the total area of the pistons. the more area you have the less force required to clamp the pads. 1 big piston could be better than 4 little ones.... just something to think about

i've been noticing all the brake talk as well...could someone please explain to me the need for all of this?? my braking system is completely stock(rubber lines and all) and i never have a problem locking up the brakes, and rarely experience much brake fade when i'm racing around the track...

how bout that dash????? Wish i could help you out with the carbon fiber. i'll ask my buddy if i can get some from him. cant promise you anything. i'll let you know prolly tonight.

I already have a piece of carbon fiber on the way. REAL carbon fiber.

I was wondering the same thing

everything thats on mine is real carbon. My buddy bought a few large sheets of it and I bum it from him when he cuts parts out of the sheets.

Is your tank cover and hood wrapped in fiber or remolded in fiber? I'd love a CF hood for my KFX!

They r both molded. i had the hood for sale a few months ago before i cut the holefor the lights. i have a few things that i need to finish the carbon fiber,...exhaust heat shield and a different case saver. i actually have two case savers if your interested. one is a molded cover like the factory cover. the other is a custom made cnc cut copy of a billet saver. both real carbon fiber. ill post pics if you want.

I'de like to see the sprocket cover.

Me too as well as a price

i guess 20 bucks shipped...i think i paid like 40 for it.

^^^^^ Now that`s what I call a pretty cool countershaft sprocket cover right there!!! Looks GOOD!!!

think i should put it back on? i do have the carbon fiber frame guards now since i took it off.

Ya i dont know how or why people want to upgrade their brakes, i have pretty much all stock breaks minus ss front lines and they work just fine, hit all 3 and i can stop on a dime almost haha, only thing is that the rear padds need replaced but those are overrated anyways!

well i put a 450r master cylinderon and steel braided lines (front) and it does stop better. i also like the adjustable lever too that comes factory on the 450r. havent done anything with the rear yet. i am wanting to put the yfz calipers on the front tho.

dont do the yfz rears, i know 4 people with yfzs who have no rear brakes

need a pic of anyone who has a 2 line front system at the master cylinder. im sure the doofus who did my lines gave me a banjo bolt that is too short.

thanks!

All this brake-hype comes from years ago. Somewhere around 1986, to be exact. The old-ass Honda TRX 250R had dual piston calipers front and rear, from it's first year in 1986. Worked great. Worked even better with SS brakelines on 'em.

Brake piston diameter, as someone mentioned above, has more to do with your braking performance than anything else, but stock rubber brake lines just suck. You'll get your biggest benefit from switching over to stainless braided lines - they just don't flex when you grab a handful (or footful) of lever.

At any rate, compare the brake piston diameter, see if you can benefit from something with more total diameter, and see what's got more total diameter. If something had more total brake piston diameter, it's gonna stop harder, no doubt.

Z brakes ain't bad at all, once you get rid of the stock rubber brake lines. Throw SS braided brake lines on there, and you'll see a million-percent increase in your braking performance. Someone hop in here, and tell me "a million percent" is wrong - tell me you got nothing from a SS brakeline conversion, if you bled it properly and knew what you were doing with the brakes...

Here's a pic of a dual front-line setup, on a 250R, Lonestar brakelines, at the master cylinder - all dual line setups should be similar with the bolt, banjos, and washers - shouldn't be anything different, no matter what model:



250R front brake calipers, dual piston, started the rage back in '86:



250R rear dual-piston caliper:



Instead of wasting a bunch of bucks on all these dual-piston calipers to try to convert, have any of you guys upgraded your stock braking system yet? SS braided lines, different pads and rotors? It's WAY cheaper to upgrade your current stuff than to find something else that might work, then make custom mounts for them (minus those YFZ front calipers that people say bolt right on). Food for thought.

Work with what you already have, make it the best it can be - and if that isn't enough for how you ride, then look elsewhere. I see a whole bunch of people that just want to drop their current brake calipers for something different - but haven't done anything to upgrade their stock brakes so far. Stock brakes can kick ass, if you mod them right.

Very informative post Normalz. Thanks! I think I will just go with SS Lines, and new pads/rotors. At any rate I can re-sell these gixxer brakes for WAYYYYYYYYYYYYYY more than I'm paying. Its like an investment.....
