i know im new to stunting but i practiced my ahole off this weekend i didnt have the money to get a dual caliper kit so i went with the gp tech kit..... that thing sucks donkey nuts for beer money... if u use the foot brake u have to pump up the hand brake for it to even work... and everytime i got it near 12 it wouldnt do nething........ just venting and pissed that i didnt get the dual caliper setup...... which setup should i go with wen i can afford it

 

just keep the kit and get rid of the master and get a 1000rr master.

 

GP tech adapters have this problem because they are only held in by the factory circlip... Get a FTI (FullThrottleInc.net) SCREW IN adapter and you will never have these problems again... bonus is that all you need is the adapter, all of your lines ETC will work with it... oh and make sure you are using a quality, stunt tested/approved master like a 600/1000RR or R1 or brembo...

 

As far as I know, all the adaptor kits have this problem. You can't use the fb and hb at the same time. It just doesn't work. You are better off having a hb system and a fb system. You get more fluid capacity and if one quits the other one still works.

 

yeah I have a few of those GP tech hand brake kits. They are only 13 mm and are a biatch to bleed. Its actually a 13mm basic brembo hand brake under that GP tech clutch cap he made. Go online....look up HOheydesigns.....buuy his dual caliper bracket. I switched all my stunt bikes to dual calipers. I have four dual caliper setups. Yes it may be a little more than you wanted to spend and its a pain tryin to find another caliper but toally worth it. The caliper brackets are perfectly machine cut so you never have a caliper draggin its brakes or off from the other. Never had any problems with them....check it out


the gp tech adapter was a good design in that it does not destroy the master trying to force threads into it but the hole on the bottom of the adapter (supply port) was way too small and the neck of the adapter was too long in that it almost sat against the bottom letting very little brake fluid flow/ pass through. It almost cuts off flow through he adapter. Thats also why at time you get air caught in the adapter result int a larger threashold/lag between the footbrake and the handbrake. Its a biatch to get right....

 

I have a gp tech and I dont have that problem. In fact I have the gp tech knockoff on my other bike, and it doesnt have that problem either.


Get a nice radial master, and do a better job bleeding it.

 

i got the full throttle set up on my drz and both foot and hand work at same time. and the brake just hits sooner. i dont have to pump before one or the other works. and i have enough stopping power that i can clutch it up from a dead stop and kill the bike with my hb

p.s. this is the adaptor set up with a nissin master cyclinder. and stainless braided line.

 

what he said

 

i got the GP tech with a 1000RR master. **** feels squishy. i dont realy like it. im gonna get a dual cal bracket. do i have to run a 636 caliper for my second caliper or can i use one off my old RRs?

 

i dont think bleeding it ne better will help the level is stiff as a rock it grabs hard as hell until it goes ne where near 12 then it just wont bring the bike back down i think ill just have to get the dual setup but i do likr the brembo and the gp tech clucth level that mounts on it ive got more room plus thats wat im learning with and im used to it

 

so if i do get the dual wat caliper should i go with

 

ho hey

 

maybe check your fluid level and adjust the way the resvoir sits so it s not upside down when at 12

 

with the bike stitting on both tires i have it angled 45dg down

 

well dang idk get a full throttle set up or go dual caliper i guess

 

I had the same setup with a old gsxr master and it worked fine. You just couldnt use hb and fb at the same time, but thats to be expected. You need to bleed it better.

 

you get what you pay for

 

aint that the truth i should have just taken it up the butt instead but it could also be partly my fault tooo

 

yeap i picked up a gsxr1000 master and the line for 40 bucks from mr.unassailable.Then order the full throttle adapter from HAI. it feels great..no leaks and you can put it on blind folded

 

it depends on if you go with a dual stock rear caliper set up or a 4 piston setup
