Brake Vibration XT660X
 

Hello, I have an 2007 XT660X and have a rear brake vibration that sounds like a very loud tuning fork when I brake. Numerous Yamaha agents have looked at it but cannot solve the problem. Does anyone have a clue how I can rid myself of this rather annoying problem. Cheers

I have a 2007 R model, luckaly I dont have the brake problem but you could try asking on the xt forum web site, they have a tech bod who may have the answer.

Good luck

Colin.

Top stuff thanks

Common disk brake vibration cures
 

Usually this isn't that hard to solve.

It sounds like a vibration, possibly a disk out of round, or badly glazed pads and damaged disk.

First, make sure ALL brake components have been checked for correct installation - spacers on the wrong side etc - and that everything is torqued correctly - disk, mount bolts for caliper, swingarm pivot bolt, wheel nuts, adjusters etc. Mounts not fully torqued to correct spec can cause it.

Then make sure the disk is truly straight - spin the wheel - if you can see ANY wobble there's your problem. Ideally should be within .000-.003" max out of round.

Remove and clean the pads (and the disk) with brake cleaner, if the pads are badly glazed, a last ditch clean with a file over the surface can resurrect them.

Finally, a spot of brake pad grease on the BACK of the pads against the piston may solve it.

Let us know how you do!

Grant,

Many thanks for your indepth advice. I'll get on to it asap and let you know how I get on.

Cheers
