ok want a hand break but i don't wanna spend the $$$$ on one....i have been wondering is it possible to totally by-pass the foot break and just make a hand break out of it and not have a foot break at all


you know by making the break line longer and run it up to the bars

Good bye no handed wheelies/no handed sit down. Not sure about the bypassing idea though... i dont think id like it much.

nope ... well i don't think so ... seems like the resivoir would have to be higher than the line.... but maybe i'm wrong.

dude bite the bullet, i bought an old fzr 1000 clutch master cylinder, 80'' of break line and a new bracket and rear brake caliper for my gixxer..cost 100$ total.

www.bonainc.com has lines
ebay has clutch and brake master cylinders, rear brake etc, you can do it for cheap

Yes, Ive seen that on a 900. The kid learned brake control on a pocket bike, then when he got a 9, he felt uncomfortable with the foot brake. He does pretty well with it.

yeah u can bypass the foot brake just mount ur resivoir up oin the handle bars and just screw the brake line into the caliper

but i wouldnt do that i would go with a full throttle inc. hand brake setup

just my $0.02

so all i would need to do, if i do it, is just take off the entire foot brake set up run break line from rear caliper to handle bars...move brake fluid resivoir to handlebars...and mount a hand lever on the clutch side...

yeah like take a front brake setup(929 is my choice) flip it upside down on the clutch side take ur rear resivoir off and mount it high on ur handlebars (higher than the brake set up pr high enough when ur in a wheelie its higher)run a cable down to the rear caliper and uses a double banjo bolt pretty simple any problems just holla ill try my best to help u out

Dbl Banjo bolt? Are you saying keep the existing rear and add and other master on the bars?

Ive been thinking about that for a long time (who hasnt) and I think if there were a check valve between every master and res on the system, it should work.

that's what I was gonna say, but with a high pressure line to the resevior. Anyone have any input on this?

Exactly.

Once I decide to start cheating, I want to use this method. Ive have about 6 spots in mind to mount brake levers.

wouldnt that leave your brakes always locked, cos. no oil could go back to the reservoirs? right?!

The way that your master works is that there is a piston with a cup cone shaped gromit on it. When the piston compresses the cone is pressed to the out side of the master, but when you let off the brakes the cone is going in the opposite direction and the fluid passes by the cone. When the piston gets all the way back to the end of the master, there is a fill hole drilled in the master that the reserve fluid enters from. Thats how you can pressure bleed brakes with out them being locked up.
Again, correct me if I'm wrong. I don't want to sound like a dick if I'm giving bad info.

yeh, but I was referring to the valves(like if the valve only lets the oil flew to one direction?) shit I don't know and my tech english is rubbish. But if you but the double banjo in the rear master, run a line to the handelbar master and leave both reservois- then you would be pumping oil into reservois so no real pressure created... ok i'm gonna shut up now:tapeshut:

I dont think the fluid is supposed to flow back into the res. In fact, once your system is bled correctly, you shouldn't need the res at all. Its there just in case your brake lines leak.

I could be wrong too though

Well that would make sense because (I know in a car anyway) the only time you have to fill your ride up with brake fluid is when there is something wrong with your system for example a leak. The only reason they flush the fluid, and replace it, is so it's not old fluid, in case you do have a leak or whatever.

that full Throttle shit is way better.. Why sacrifice havin a foot brake when Full throttle is so cheap.. My opinion

IMR-Merlin

Fluid will backflow into your reseviors if you run 2 masters. When the master cylinder piston is fully extended (foot/hand is off the brake) it will have an open run to the resevior. So if you are running 2 masters and 2 reseviors, when you compress one brake, it will feed back into the other one and not create any pressure. I have seen some systems that feed from the hand brake to the resevior input line on the rear master. So, the front master cylinder and resevior act as the resevior for rear master. Only problem with that set up is that too much pressure is created where the rear resevior was connected and you get leaks.

I agree with you here. Not to mention it would be way safer because if for whatever reason you can't get your hand to the brake, you have your foot in case, and vice versa.

this is the setup that GPtech uses, its the little button that goes there, also the outermost boys have it setup like that, it seems to work fine for them. once i get my 929 i will have this setup, so i am hopin it works good.

We tried them for a while but had some fade problems with it and also one leaked all the time, but fill me in when you get yours.

my boy schwartz has one on his f4i and it works great, what he was sayin to me is that with the gptech one you need a master cylinder with diameter size smaller then fourteen, like a ducati clutch master cylinder, thats what he has on his.

Ok, but what if you have a check valve between EACH master, and its res. That would solve the problem wouldnt t?

Way to much plumbingand more room for leaks

If you only use the crush washers 2 or 3 times, they wont leak.

wow yall really goin of of what i was sayin was move the rear resv. to handle bars and get another breaklever and longer cables and hose and run to back

basically just moving tha foot break to the bars

For the record, I would say yes, but only if the lines leading out of the master to the resiviors were rated for high pressure.

GPtech had a great idea, but the units that we tested (IMR) had some problems that they were working on. I know that I personally didin't test or install one on my bike, so I can't confirm or deny any know problems with them. I saw one bike that had a leaking problem on the rear master and one rider had his rear brake completely fail after 10 runs practicing 12's. But I didn't install these units and wasn't riding the bikes, so I can only pass on what I heard.

it would be just as expensive. and your rear master cylinder would look goofy on the handle bars

I want a break lever connected to my eye lids - So i can . well. i was going to type something funny but i lost it. nevermind.

So you can look like you got something stuck in your eye while riding a slow wheelie. Of course. Go back in your box.
