2014 ES Rear Brake Adjustment (Saw the bolt = better rear brake action)

I have been working on my low speed "Friction Zone" riding.

One major action in friction zone training is to 90% only use the rear brake and often drag the rear brake while feathering the clutch.

I adjusted the rear brake hasp buckle and lock nut and it helped position the rear brake with my size 13 boots better.
HOWEVER: The OEM limit adjustments did not allow for me to place a relaxed boot on the brake for any length of time.

From past KLR-650 use .... I had once cut the rear brake lock bolt and I just this morning ... did the same on my 2014 S10 ES.

OVERVIEW

I removed the covers for the rear brake slave cylinder and removed the brake connection and hasp connector but left the nut on the bolt threads ...

I then added a second nut and after positioning both nuts so to align where I wanted to saw the bolt, double locked the bolts.

I then used a set of locking vice grips and held the two locked nuts.
(note: Having metal debris near a hydraulic seal and having side load on the seals during the hack sawing worries me but I tried to be clean and gentile)

Now the "not fun" slow part. I then used a fine tooth hack saw and took my time (20 minutes) to slowly cut through the bolt near the shoulder of the lock nut.
(Then used a file to smooth the cut ends and chamfer the bolt)

(note: Holding the vice grips with one hand and sawing / filing with the other hand is a pain)

Removed the lock nut and cleaned the metal debris around the threads ... and re assemble the rear brake ....

Took me an hour going ... slow.

Will play with it for a while to see if the adjustment works for me and will report back later.

I have done the slow speed maneuvers practice, dragging the rear brake and feathering the clutch. I have noticed the angle of my foot seems a little sharp and was thinking I may have to adjust my brake pedal. I'm getting a RDL saddle soon, though, so I'm going to wait until I get that before deciding to make any adjustments. My stats are similar to yours, 6' 2.5", size 13 boot. Looks like a nice job, though!

???I don't understand....what advantage does the modification give? Been to some of those rodeos. Never needed more brake control, clutch control and weight transfer were always my critical concerns. ???

Depending on the side of the rider and the size of the rider's boots, you will have your foot/boot pressing down on the rear brake pedal while at the maximum adjustment range. Cutting the bolt down allows you to lower the rear brake pedal more and thus keep a larger person's foot/boot (In a relaxed position) and not activate the rear brake.

In police rodeos (Motorcycle course) you need to be in the "friction zone" and drag the rear brake to some level. Having the rear brake at the right level makes it easier and less stress on the rider.

Has some details on setting up your bike for the friction zone....
