How to adjust rear brake pedal height?

[lukinhasb]

I couldn't find anywhere in the manual regarding adjust of rear brake pedal height, a local mechanic said it has to bleed out some fluid for it to lower, but I would like a second opinion.

You ever wonder how some people have the jobs they do?  Remove some brake fluid?  Bad advice is bad!   


Anyway, it's been a while since I owned a GS so I could be wrong but there should be a threaded rod coming out of the master cylinder that connects to a yoke on the back of the pedal.  Adjusting the pedal's height should be as simple as turning this rod, or it may require detaching the yoke from the pedal in order to turn the yoke itself.

There may or may not be a locking nut on there as well you'll have to loosen first.

I dont believe you can adjust the rear brake lever location (atleast not by any means that doesn't involve bending sheite).
Cool.

Couldn't you just unclamp the lever from the spline, pull it off, and then put it back on but rotated counterclockwise a few notches? Apologies if I'm mistaken.

Not a gear shift type spline, its a arm with a peg welded to it, and the part that acts as the "brake" is the back part of the lever, across the pivot from where your foot makes contact.
Cant change it by rotating @ the pivot even if you can remove the pivot, you gotta bend some stuff ...
Cool.

Wait, I think qc is on to something.  Look at this pic.



The pedal is splined at the end to receive that little control arm thingy (super technical term) with the springs attached to it, this is what attaches to the master cylinder.
You'd just have to rotate that part on the splines to move the lever up or down.

I'm confused, since I've personally lowered my rear brake pedal quite a bit. (On my 1998 GS500E)
- It's some time ago, however I remember messing around with a locking nut and rod, that kinda typical adjustment system.
I don't really remember tbh. I would have to look at it again. I'm pretty sure it was more about taking out the slack, which there was a lot of.
I then also had to adjust when the brake light contact engaged.

I think for adjusting (taking out slack) It's the bottom nut.



So it's very possible, unless I've screwed something up? But eyy, I haven't noticed any problems

@kok

That's the same way my Ducati monster is setup.



Same way my Buell Lightning was setup as well (excuse the broken footpeg).



No picture of it but IIRC my Honda CB500F was setup the same way as well.

Don't think I ever adjusted my GSs pedals but at this point if you're suggesting it has this setup I'm inclined to trust you.  It seems very likely.

In such case I'm going back to what I said in my first post, undo the lock nut and either spin the rod or spin the yoke to raise/lower the pedal.

If you thread that in much, it will hit the brake pedal arm's face and not go much further.
If you screwed it out then it will leave the locknut's thread grips. However I guess it should let the lever move enough cos its got a 4:1 leverage ratio I think. I guess I never looked into it, cos I didn't need that, cos I never used it.
Sorry about misleading Y'all.
Cool.

As long as it's still on the threads the lock nut will work, unless I completely misunderstand what you mean here.

True, you would have to leave a few threads in, essentially dont turn it past where it can vibrate itself to freedom.
Cool.
