Hi, new member here.

I'm afraid I caused major damage to the front wheel and brakes of my 2006 metropolitan. :(

Here's the story:
The front brake lever was loose. The cable need a little tightening.
Unfortunately, I over tightened and engaged the front brake.
I took it for a ride and rode it several minutes before realizing what I had done. It has been stuttering lately, having trouble getting up to speed. So I thought the resistance was due to some stale gas, clogged carb, etc. That's why I didn't think that the brake was too tight until it was too late. I thought that the brake mechanism would compensate for the tight adjustement.

Well, it looks like I toasted the front wheel and brake. By the time I figure out what was going on, the front hub was visibly burned. Brake fluid was leaking from the front axel. It squeaks when the brake is engaged.

Questions:
1. Without any other details, so what am I looking at as far as repair? I haven't removed the wheel to inspect the damage. But again the right side of the wheel is brown.
2. Is there a shop manual for these scooters?
3. How difficult is it to rebuild the front brake? I have other motorcycles, and looking at some of the drawings of the front wheel, brakes, they do not look that complicated.
4. Will I have to replace the wheel along with the brake mechanism?

I also tightened the back brake. It is squeaking a little but doesn't look to be damaged like the front is. Hopefully, just a pad replacement?

I feel like a complete moron, idiot, dufus and many other not so nice names.

Any help appreciated,

Greg

First thing is to pull the wheel apart and visually inspect. Might be able to salvage the wheel and only need to replace the shoes. Was probably liquified grease coming out the front, since these are mechanical drum brakes.

Thanks Old School. I'll pull the wheel and look it over this weekend. I'd be thrilled if all it needed was new shoes. The brake still works, just squeaks.

Get some 320 grit sandpaper and 'rough up' the drum while in there. Probably all glazed over. Do the same with the shoes. Lightly so as to remove any glazing, but not too much. You want to sand so it looks newish, but if you sand too much material, you will need new shoes. Sanding the drum(hub) enough to roughen it up as it probably has glazed friction material from the shoes coating it.

Was planning on sanding the drum as you describe. But your details are very helpful.

I'm anxious to get in there and see what the damage is. But probably can't get to it until later this week.

Thanks again,
