Parking brake blues By luckydog (Read 727 times)

For those of you who have never seen a scooter with a parking brake, its just a lever under the seat that engages the rear brake to prevent thieves from rolling your bike away.

Point A and B were 1.5 miles apart. Rode the whole way with the brake on.

When I got to the place I was going it hit me. I noticed that the rear disc brake had turned a little brown (the parking brake lever never really applied that brake that hard- just enough to make it hard to push by hand).

Lately I've been noticing a problem @ WOT, especially on turns after a stop light.

The bike moves forward, then the engine "disengages" for a brief moment, moves, does it again a little bit, then goes back to normal.

I was curious if I burnt out the clutch shoe or something else? The brakes have plenty of stopping power even after the incident. Just wanted to get a second opinion from you guys to see if I should be worried about it.

Try Occam's razor.....hopefully it's the belt. Have you pulled your CVT cover and looked around yet? The belt might be toast but if that's normal and your clutch housing looks like it got hot, I suspect that's your problem. I doubt it's the variator, pretty simple and wonderful concept, not a lot to go wrong; but hey, anything can fail. So first pull the cover and let us know. By the way COOKEES is a CF dealer and he's be glad to sell you one..........I MEAN, give you some tech info . Rich

My majesty has one on left handle bar and it will lock scooter and stop it from moving. best thing since sliced bread. since a scooter doesn't have any resistance from rolling when engine is stopped a slight push will drop it off the side stand. a motor cycle is normally left in gear so they will not roll off the side stand. when you get it fixed see that it is adjusted so you can not move the scooter with it on and you won't forget and leave it on again! john

its ~22 mm which is within limits according to the service manual. Looks normal (I think).

I noticed that it happens on sharp turns at a stop, could it just be that its a cheap stock band thats aging and this kind of slippage is normal?

That looks normal to me but it's hard to tell from the picture. The Big Guy had a great article on his web site about a CVT check up that included belt inspection. You might PM him and ask if he's got a link to that. Clutches normally "grab" a little now and then if they get out of synch with the engine RPM while coasting, I'm sure you've experienced that, I have. If it's excessive I'd say the clutch took a hit pulling against that brake load. It looks like you have some wrenching experience, why don't you take the clutch housing off and look around? Rich
