    DCT Left Hand Rear Brake Lever ?

    Having seen a few bits of info on the AT forum and now the video below about the addition of a rear brake lever for the handle bar I'm really interested to try it. With a knackered left leg, I didn't realise how much I used the clutch to modulate low speed manoeuvres. because I have to have my left foot up on the peg, I cant use the rear brake coming to a stop or moving off or in moments when filtering and stopping suddenly etc (as my right leg needs to be holding me up!) and the suspension dive on the AT doesn't help either.

    There are a couple of rear brake lever systems out there, for dirt bikes. The Ox Brake kit, which adds a cable lever to the rear foot brake lever and Rekluse do a hydraulic one that replaces the master cylinder reservoir. I dont think I can replace the AT master cylinder with one for a CRF450 (which would mean I can add one of those kits) , as the brake piston is much smaller, so surely the bore of the master cylinder piston is smaller etc?

    Looking at the video below, is there any reason why I couldn't do everything he did but omit the rear master cylinder? If I don't want use of the foot brake lever, surely I could just add a joint block between the new rear brake line and the new handlebar master cylinder (banjo to banjo) somewhere next to the old master cylinder. The XADV master cylinder obviously has the correct leverage to work. Id literally just need an aluminium block, drill a hole through it, tap it for a banjo bolt each side and connect the existing and new brake lines together? Meaning It can return to stock very easily and removing the need to try and tap / thread in a plug into the stock master cylinder (where the reservoir connects) Thoughts?

    The only thing that concerns me about this has to do with Simon's (haditlowered) off on his GS. If I recall he had muffs on his bike, and a slow, ish speed off with him going over the bars created a world of damage for him and his wrist - not to forget the f up on his treatment. But the actual location of the aftermarket kit on the bars caused the initial break/damage. That hand brake lever in the video might act in a similar way in the event of an over the bars dismount. Removing it to replace might be the answer. pS, why does the dct need a handbrake? Might be stoopid question, but one I forgot to ask!

    I thought the brakes were linked? Might not need a lever at all. JJH

    Apparently if a motor vehicle cannot be parked in gear it must have a handbrake.

    Sorry I read your post again. You want to be able to just give a touch of back brake at low speed. A lot of racers and stunt bikes have set ups like that. Maybe talk to someone with that background. JJH

    I am happy with the muffs for road use but don't think I would have them for off road use where the risk of going over the bars in an off is much higher. I love the idea of having the rear brake up on the bat for slow speed control. This worked a treat on the Integra when combined with the dct. However I think it would be a mod that had to be disclosed to insurers as it is a fundamental change and might be frowned on or invalidate insurance if not disclosed. I did not like the position if the handbrake in the video. There must be an alternative latching mechanism that would work. Shame Honda does not offer it as an option.

    Thanks for the responses guys! I too don't like that handbrake lever, but theres no need for it to be on the handlebar anyway in my opinion. you could mount a ratchet lever anywhere really and just buy an appropriate length cable to suit.

    JJH, a bit of outside thinking there was excellent ! Got me searching and I found this billet adaptor to plumb a second brake lever into an existing rear master cylinder! Below is a pic of the AT one and the second picture of a universal adaptor in what looks like a very similar MS !! That would save the whole threading/taping of bungs etc into the MS.

    If, it relates to a modification due to a disability; it is unlawful to put an extra loading on the premium however they are entitled to charge extra because it will cost more to replace vehicle with additions than without. Hopefully that makes sense.

    Have you thought of a 'thumb brake' Crotchrocket?

    I have similar issues to you but on my right side (and can't use a back brake at all). I'm so used to only using a front brake that it's not really an issue with me but, every now and again, I wonder about trying a thumb brake.

    The other option, is to take the handbrake cable calliper off and replace it with a hydraulic calliper to a new master cylinder. Though i'd need to look at the mounting points and if they are strong enough. Or get a bracket fabricated for two callipers, like the stunt guys

    Very common in racing and you do see them on road bikes sometimes (race rep type things) as well as the odd dirt bike.

    Here's a link to one that retains the rear foot brake as well (or you can replace the foot brake if you prefer).

    Looked at the rear brake last night, the carrier extends down for the DCT hand brake calliper, so both brakes share the same strength bracket (part 8 on the pic) which is good news. I cant see any reason not to just add a hydraulic calliper with the XADV master cylinder, for a completely separate rear brake?

    I'm not sure about the suitability of a hydrolic handbrake? It would make more sence to have a cabel oporated rear brake. Oviousley not for brake performance or more importantly abs. I'd be looking at somthing like a hydrolic clutch lever? Plumbd in if the piston was anyway the right size. JJH
