Rear handbreak setup!!

supermotard69 · DTR Respected Member

Has anyone done this on a Dtx or Dtr because if so id be interested in how to mount the rear calliper...becuase if i can run this as a setup for stunting there would be great things to come!! im going to tryn get a video up soon to show you guy's where im at when it comes to wheelies and stoppies,doughnuts & stuff..because with the hand brake..i could progress so much further with slow wheelies and then to learn circles mabye if it goes well...well who knows haha ;D

in the past few days there's been quite a few riders who ive never met who are saying im progressing quite well...even one said.."oh do you ride show's?" at this point i just pissed myself like...nah just goofing around really!

he then said i should look into it more and his friends agreed so here i am..looking into it more that is!

any advice would be great!

with a caliper you would need to get a new caliper bracket/mount cnc'ed.

for now you could always just run a second line to the rear master cylinder and loop the same system with 2 masters.

seen it done a few times the main stunters run 2 or 3 calipers as the bike are so much heavier i reckon just one caliper would work on the dt.

its an interesting system that i was gonna look into.

too cnc a new bracket would be very hard and very expensive, look to adapt the current one or maybe combine thhe dtx and the dtr as the are slightly different, maybe knitrting the two together u can make a duel caliper bracket...... just a thought i had lol

ShaunyBoy · Guru

yes exactly that, would look crazy tho lol

What do they use to operate the brake once its been setup and where do they put it, surely not another similar sized leaver on the bars to operate it?? Lol, intrested in doing this

ToySoldier · DTR Legend

got a lead on it and just working out the kinks atm

basically on stunt bikes they use a master cylinder from a sports bike they have mastercylinders with a cable to a bottle so you put this upside down with the bottle the right way up but your talking £50+ for master cylinder and normally they go Brembo so thats 150+

but when you think there stoping a 200+kg 600plus cc bike so we dont need that on dt's

so my plan is a master cylinder form a gilera runner there made to go on that side and for rear calipers plus it will kinda match the dt one

allso just getting info on the length of a rear cable from a runner as they go from the bars to the back wheel on peds so there long should be right side from the bars of my dt to the rear master cylinder and there £25ish for a braided one bonus.

plus this little adapter that is cheaper and easier then welding up brackets.

the adapter eliminates the rear reservoir and you put the hose from the front master there so it works on the back brake

got this of some dis site

Right leg (Amputation or restricted strength/mobility):

This is usually a simple matter of transferring the rear brake control pedal to a handlebar-mounted lever. This can take the form of a thumb-operated lever or a more conventional lever mounted in tandem with the front brake lever or clutch lever.
Where the machine has a twin disc front braking system one of the callipers can be linked to the rear brake system (as on many Moto Guzzis) and the other front calliper used with a thumb-brake or tandem lever.
Another method of adapting the rear brake system is to use a linkage to transfer the brake pedal to the left side of the machine. This can be sited either alongside the gear pedal or directly behind it for heel operation.
1. Left or right hand twin levers
2. Left-hand thumb-brake (7/8" bars only)
3. Crossover linkage to left side of bike

some levers and systems

this is what you need bet they not cheap

seen some one diy some thing like this in the past and just put clutch on a thumb lever and put back brake lever in its place by just running a longer hose kind thing

Not sure if it is any use to you, but the Peugeot Jetforce uses a twin caliper set up (lol), maybe there are some parts there you could use.

Double caliper and double lever setup.

ToySoldier · DTR Legend

mdk with the one photoed there both fluid so useless to us lads and seen the thumb ones useless tbh on offroad bikes mainly aimed at sport bikes.

tbh 2 or 3 calipers are only needed on big heavy bikes for serious stunting on a dt you only need one caliper its just a pain sometimes to work it out as your going 2 imputs into one out put

and when you press one in it will push the outher out if that makes sense

Errr..thinking at this time hurts for me as ive just finished a nightshift!

1.Well the most simple option is a custom lenth braided hose and a "moped master cyclinder" and to just do..away with the footbrake! which in its self is so simple..but a **** idea really because i like my rear brake being under my foot.

2.Use toy's sugestion with good welds and maybe a hole drilled and bolted to the orginal caliper bracket it should hold sweet even under vibrations..

3.To go all in and buy a 636 rear piston and then fit..a self tapping banjo bolt to where the fluid resivoir attaches and then run a brembro lever off of an r1 with a raised fluid pot.

options 1 & 2 are way cheaper by far and with bit of faffing it should work pretty damn well!

Cost is the main thing really i wouldnt mind just disconnecting my rear brake for a few days to run the hand brake just to get a feel before i spend cash and time slapping my engineer friends into custom fabbing stuff for me! im felling toy's suggestion but we shall see!

Them Duel brakeing systems like in MDK`s picture are like $2000 WTF

thats new i did not know that about the jet force quite intresting tbh lol

got a mate dropping me a runner master cylinder with line rear caliper and pads in a bit for a tenner lmao stunt dtr hear i come XD

supermotard69 · DTR Respected Member

Well I was just doing some research into that self tapping adaptor and a few american's on a forum were saying the one for the kawasaki 636..also fits the drz...so any one have an idea if the drz rear master is the same as the dtr it's a long shot..but it's worth asking before spending

ToySoldier · DTR Legend

if they fit into the drz without much problem i rekon it will fit the dt if you look the bit you need to remove looks the same as the dt when i get some money ill buy the adapter

supermotard69 · DTR Respected Member

See I'm thinking it will and should fit,but like yourself I am also waiting until payday :D I'm just hoping it will bolt in place! because obviously where it bolts into..well the original resovoir is circlipped in place so I'm still having doubts about this adapter..

ToySoldier · DTR Legend

well from looking at the drz that is circlip as well im thinking of buying a spear rear master removing that plastic part and hoping i can just tap it and thread that adapter in

for me its either the end of the month or if some of the people who owe me money pay me XD

i got my master cylinder lever and lines and the lines way way way to long hahaha so he going to bring around a selection of lines for me to try but i rekon a front brake line from a dt will work i have a spear i would try but this master i have doesnt take banjos so restricted to ped lines atm lol

supermotard69 · DTR Respected Member

I've spent a good 4hrs studying master's and this teardrop adaptor..what we need is a list of bikes which this valve simply bolts onto and then we could just eBay hunt for pictures to see which comes closest to the dtr one..

We know so far it fits the 636,the cbr models for sure and apparently itsselftapping but I'm not so sure!

ToySoldier · DTR Legend

soposidly cbr 125 masters it fits i got a fake import version master on a spear bike i might pull off to try

supermotard69 · DTR Respected Member

Yeah but then how are you going to mount that master dude?
:D there's so many lil complex things!
