[Fixed] Brakes: The 1000$ mistake!

I was afraid to get the fluid aerated with time :S

If you confirmed me that its not a problem reusing fluid i will reuse it ... and it will be cheaper in the long run

As long as the system is really clean from a fresh rebuild, I toss the fist 1/2 pint or so, then as is is coming out clear I save/ refill. Give some time between bleeds as this helps keep the fluid from air bubbles.

thank you!

Once i receive my 28 inch long brake pipe [to rely right caliper to left] from z1 enterprises i will begin to work on the calipers.

I wish you the best riding season for you guys. (meh it looks like its gonna rain all the summer here )

See if you can use the stock calipers with your new discs.

Here's a pic of a vintage "Kosman" Suzuki GS brake kit. It replaced the stock discs with 330mm discs and used brackets to mount the stock calipers to the forks. Every thing was stock (OEM) except for the discs, brackets and braided lines.
Stock discs are shown to compare them to the "new" discs.

that top right rotor looks almost like a drilled z1 rotor

ok guys here's my update:

New set of gpz calipers are way better ! OMG i've partially found what was my problem. The GPZ MC is different from my KZ550 spectre 83 (beside inclined)... The piston is smaller !!! That's why i had trouble using my gpz calipers with this MC and also the new one on ebay.... I think recent calipers from today require less fluid movement from the MC to brake than from the gpz one!

I've passed my inspection today the guy never checked the brake lever (anyway it's almost perfect) ! so much stress in the last days for nothing!

BTW, for my first long ride with this bike i've noticed 2 things. I must increase the idle RPM to 1500 instead of 1100-1200 because it will fight to stay running when the engine is hot ( drop to 800 rpm then eventually die if i don't blip the throttle often)

second thing only when the engine is hot, gentle valve noise is happening (click click click... i have a full face and i can hear it when riding at low speed but you have to concentrate on it)



ps: sorry for to much information thrown a the same time ... I'm very excited ... I'm enjoying every minutes on this bike !!!!


Thanks to all !

awesome!!!!!!!!!

bikes run lean when cold, and get richer as they warm up. if it idles fine when cold(lean), u may try leaning out the mixture screws a bit , to see if it will idle better when hot.

Good news Laurent, looks like you'll be riding this summer after all!

You are right sir !

I'm already riding the girl :lol: ...

My brake project is on hold for now (i will take the time to study what i will install this winter ... since i've already paid for the oversize discs)

awesome!!!!!!!!!

Hell yeah!

Wish you a very nice riding season for everyone and please be safe

If you can find some 2007 suzuki vstrom calipers are very close to the stock kz ones there are some strange cooling fin things on the wheel side of the caliper but those could be ground off I measured my buddys vstrom brakes and they seem like they would work. The bolt holes to attatch them to the for are closer together but a bracket could be made easily. I have not actually pulled his front caliper off and tried it on mine but it would be worth looking into.
