It's always somethin....

:head bang:
My front brake lever doesn't want to return all the way, so the dang brake light tends to stay on after using the front brake, unless I push the lever forward after using it. Sometimes, just the wind blowing on it while riding will move it back far enough to turn the brake light on. It's dang annoying.
I've taken the lever off, and lubed both sides, and the pivot bolt. No real help there. I think the dadburn piston in the master cylinder isn't coming all the way back out, but not sure yet. Sure hate to dig back into it if that's what it turns out to be. I rebuilt the master last year, but this particular issue has just crept up recently. If I find that the piston is fully returning, I may glue me a small shim onto the lever where it presses on the piston, so it will push the lever far enough forward to to compress the brake light switch. Or it may be easier to glue a shim on the light switch end instead, since there's a LOT less pressure on that end. I wonder if the end of the brake switch plunger has worn down enough to cause this?
It just never ends, does it? :builder: :fiddle:

Just like being married, :shock: :smilie_happy:

There must be a reason the piston isn't putting pressure back on the lever to seat it home.
Could the brake be dragging as a result?

im dealing with a hydro clutch lever doing that ...cause seems to be general wear everywhere about it and like no real fix so ive done things like your saying to get some lever movement

Joel, I had the exact same thing happen. It is the switch. They are replaceable and cheap too! It comes right out. I bought mine from Western Honda. Well worth the $15. It is part number 35340-422-013 (part 1 in the fiche) and is still available. Here is the part # for an '81:

+1 on the switch Gerry :yes:

Could it be the little bleed hole is partially plugged? I know to get a return on the plunger it needs to bleed someplace.

That's what it seems to be, Dan. I payed more attention to it this evening, and once I use the brake, the lever is loose for a few seconds, then it tightens up. The piston is definitely not returning to rest as quickly as it should. Brakes are not dragging, best I can tell. The switch plunger does appear to have worn down on the end some, but since I now know the piston will eventually come all the way back out to rest, I'm not going to try to shim anything just yet. I'll dig deeper this weekend, and see if I can determine WHY the piston seems to be hanging that last little bit. Just weird, because there is a new return spring in the master to push the piston out. I'm thinking the dang rubber seals have swollen, and that's what's causing this. Cheap azz crap... :rant: Prolly why my rear brake doesn't seem to work all that well, either. oh2:
