Left hand rear brake set-up!

Hi all,

I'm interested in a good left hand rear brake set-up for the R. Saw the OXbrake but as it uses a cable instead of a hydraulic cylinder it is said to lack power.

So I'm looking at the left hand rear brake kit made by Rekluse. The problem however, is the R's rear master cylinder isn't supported. So I'm thinking I'll swap the master cylinder out for one that is, and install the kit.

So would anyone be able to tell me which of the following Yamaha rear master cylinders would be a straight swap for the R? Rekluse offers the left hand rear brake kit for all of them:



Thanks heaps in advance!

Sorry got the photo working now

Anyone know? Or know where I might be able to find out?

Cheers!

Maybe checkout 50stunt.com.

Yeah looks like good stuff but not interested in a dual caliper set-up. Hence the Rekluse, which runs through the original master cylinder. Thanks anyway

http://www.clake.com.au I emailed them and they have a setup to adapt the clutch with a hydraulic slave cylinder for the clutch at the engine Side. $$$ but supposed to be slickest setup.

Thanks jk. I'm aware of Clake but wasn't sure how they would get around the cable clutch, so that's good to know. I wonder if that would make the clutch pull super light like their other set ups? Wouldn't mind that! I knew is was expensive but an engineer friend of mine said he wouldn't be able to fab something up for much less money than the Clake. Maybe I'll give em a call!

Lewi,

What did you end up doing for a solution?

Hey Poco,

Well, I don't have one yet! I've been riding the bike solidly as is and loving it. I'm still very keen to get an LHRB set-up and if I do, I dare say I'll go for something by Clake. Either the Clake 2 or Pro Lever should do nicely! Really exxy though...

Just thought I'd throw my 2 cents in. I'm running the OxBrake for the WR450F and it works pretty well once you upgrade to the WR450F rear brake assembly. The biggest issue with the LHRB on the WRR is the rotor is too small to get proper control of the wheel. To give you an idea of how much bigger the WRF rotor is compared to the WRR. The WRF is almost the same size as the front WRR rotor! A total of 15mm more in diameter over the stock rear WRR rotor. This equates to much better control which allows the rider to lock up the rear wheel if desired.

What all did you upgrade from the WR450F? Whole rear system from master to caliper and disc, or just the disc? I am planning to install an Ox-Brake this winter and it sounds like I need to include the WR450F upgrade in that project

As far as the rear brakes go, you only need the rotor and the bracket for the caliper. If memory serves me right, the caliper bracket is appox. 7.5mm longer than the WRR unit. Hard to believe it makes that much of a difference, but its worth it IMHO. If you're looking to upgrade the front to a 270mm kit you only need change out the rotor bolts to the YZF pieces. Hope this helps

Now if you really want to treat yourself to a nice LHRB setup I'd suggest one of the clake systems. I purchased the Clake PRO lever which has the clutch and rear brake integrated into one lever. This basically means you have to be comfortable with clutchless shifting up and down. Fortunately, the rekluse system makes clutchless downshifts, much more forgiving, especially in the lower RPM as the clutch is close to disengaging. Having ridden a bike with a Clake 2 setup, I'd rather have my clutch and brake separate, but I've been happy without. My only issue with the Oxbrake system is the vague feeling associated with a cable actuated system and the somewhat clumsy orientation of two separate hand calipers. But if budget is a concern, then I'd go with the Oxbrake.

Sweet thanks for that info just those 2 parts makes it an easy upgrade.

I also had the Clake systems recommended to me by a guy on a tricked out Husky in Moab last month, and they are clearly the better setup but my are they pricey.

I dont ride single track just been exploring more difficult Jeep trails lately and sometimes a rear handbrake would be nice at low speeds or stopped on an incline. So I dont see getting spendy on a Clake or Rekluse, the OX sounds like the perfect level of price and function
