rear wheel drag
« on: August 26, 2015, 10:36:22 PM »
Just wondering if anyone knows, when I put the DT300 on the center stand and grab the rear wheel and give it a spin, there is quite a bit of resistance/drag there.
Not sure if its from the brake pads making some contact or just the CVT but it takes quite a bit of force to spin it and when I let go it spins maybe a 1/4 turn then stops.

clean and lube the brake sliding pins and plates,  the drag will be much lower,.  and check how the wheel spins with out the pads in there,.  did that last week,

I second Scroll's assessment. There will be drag due to the CVT and I think its a natural thing.

Brakes. I finally ignored it. Piston does not retract like front.

I have to re-tweet here, I went out after posting this and laid on my side, put my hand underneath the wheel and gave it a spin and it`ll spin one revolution give or take 1/8th of a turn so its probably just my paranoia more than anything.
I will be greasing those slide pins for the brakes though, thanks for that dee.

I gotta add to this thread: Old DT the rear brake always dragged especially after using it and it would be a bit hot. New DT300i does NOT drag at all. What's the difference?

fresh grease in the pin holes,  I found out the difference when I cleaned the pin holes very well, and re greased it

You should grease the pins with caliper lube only  ???

I did all that about three times on the old one and it seemed to make no difference. The latest theory I came up with is 1. the "weep hole" in the master cylinder was slightly out of position not allowing the fluid back in the reservoir or 2. the clearance between the lever and the master cylinder plunger was too small. Other than those two bright ideas I haven't a clue.

Some early NSS300 FORZA's had the same issue with dragging rear brake. The worst case (warrantied) repairs involved warped discs and worn out pads.

Only a newly manufactured caliper fixed the problem.

And, I'm feeling a little peculiar.
