Re: Rear brake lever to high

The pin with the cotter key that connects the foot brake pedal to the rear master cylinder should have a little play.  If it's tight you are putting pressure on the brakes.

Hey thanks for the tech tips, I tried what you guys recomend and it still dont jive. any other suggestions ? a welder freind of mine told me if he cuts and welds the brake lever it will weaken it, and probably brake in a get off. He lectured me on bad foot positioning habits. Then he went on about modifying the foot pegs instead, possibly raising them.  The last time I gave the issue my full undivided attention made adjustment ect and it still wasnt enough adjustment.  I love my kx 5 even though its doing this to me . cant wait till it gets right.  also my IMS clear fuel tank started leaking under the seat looks like hair line cracks.  bummer.  got a clarke 4.0 on the way  :-D thanks again for the responce even though i already done and tried the adjustments. :?

Its ok when Iam standing, but when ever I sit down I cant get my foot to bend up that high while still on the peg.

I have tried the adjustment only to have the rear brake over heat and fade out completely. 

If anybody has any ideas i sure would like to hear them.

Im thinking of cutting/ modifying lowering it at least an inch.

please help me with any tips.

thanks

When you adjust the stop bolt, you also have to adjust the threaded clevis at the rear of the brake pedal. You want to feel about 1/4" of free travel befor you feel some braking resistance. I am also thinking you have moisture in your rear brakes. When your brake fluid heats up the moisture vaporises, and causes your brakes to fade badly, and feel spongy. Completely flush your fluid out, re-bleed your brakes, and you should be all set.

I know this is an older post but I just wanted to add that I have the same problem with the brake lever.  I adjusted it to where the front of the brake lever is as low as possible in relation to the footpeg and it is still not low enough for me.  I'm 6' 3" tall and when I sit down on the bike up close to the tank, my toes point almost straight at the ground so there is no way possible to use the back brake without lifting my foot completely off the peg.  While standing in the "attack" position up on the bike with my shoulders over the bars, it is still uncomfortable to raise my toe high enough to sit atop the brake lever while keeping the arch of my foot on the peg and almost not possible in riding boots.  I have to push my hips back over the rear of the seat/rear fender with my knees locked to get my toe high enough to rest over the brake lever without actually applying the brakes.  Therefore, no riding wheelies for me as I cant "cover" the rear brake in a comfortable and in-control position on the bike.  Hopefully this helps some of you understand what streetsweeper is referring to. I knew exactly what he was talking about because I deal with the same thing. There is not enough adjustment in the lever to cure this problem for me.  I personally just deal with it but would be very happy if there was a resolution to this problem. 

Spider:
I had the same problems with my brake pedal. Trying to use the adjustments wouldn't help enough, being 6'2" I needed a little more. What I wound up doing is taking a large crescent wrench (16") to bent the petal down enough to work for me (about .75 inch).
