Most of the time just tearing it apart and giving it a good cleaning is sufficient.

If any of the seals are bad, you can order a rebuild kit.

I did the same on my Tuono just last fall:


2009 Aprilia Tuono - Ginger
2001 XR650R BRP (Big Red Pig)
2006 Honda 599 - Ex wrecked it :-D
2007 Honda CB900F (sold)
2006 Honda VTX 1300C (sold)

That's a great video, thanks for the link.

I just noticed that my front bakes are dragging - not enough for burnt brake pad smells or warped/discoloured rotors, but the wheel is reluctant to move at all.


Looks like I'm going to go for a rebuild/major clean-up in the near future.

+1 could just be caused by air in the lines.

Probably just needs a good cleaning and fresh flush. Nissan 4 pot calipers are very easy to rebuild, I have done a few sets and just reuse the pistons 95% of the time and just order some new seals and pads.

Clean everything really well, then use some synthetic lube on the slide pins and piston to pad contact points on the back of the pads. She will be good to go.

This very well may be. I have a couple of rebuild kits that should be coming my way on Thursday, and that will be the first step : bleed/flush the brakes.


I've got no excuse for it, but the bike was purchased a year ago, and the fluid is from then. Who knows how old that stuff is.

You guys were right!!!



Bled the front brakes this morning, and the wheel doesn't drag anymore!

YES!


The caliper seals were late coming in to my local shop, so I figured that being out a couple of hours and a few dollars for brake fluid was worth a shot.

Good to hear!

After I bleed my brakes I use a heavy ziptie to hold the lever tight against the bar, crack open the reservoir cover .... cover it with a loose plastic bag and leave it over night.

It really helps bring the "feel" in the lever up and get out any small residual bubbles.
