Front brake disc rubbing caliper

[ksmoker2 15]

My front brake caliper on the right side is rubbing the disc. I pulled the wheel off and everything seems to be aligned properly. No adjustments for this that I'm aware of. The disc isn't centered in the caliper. The left side looks fine. Anyone else with this issue?

I'm assuming you brought this back to the dealer ànd had this checked out. But I wanted to say that being a machinist and dealing with castings, sometimes they don't line up properly in the fixture holding them for machining or they get misloaded. You probably have a bad caliper mount and should get it replaced.

Someone else recommended loosening the axel pinch bolts, pumping the front end up and down and getting that fork leg to settle on the shaft better. That may help also.

Mine had the same issue and I did the same procedure as Svrider which helped . It didn't center it, but pulled it away from the caliper enough to clear it. Waiting for a response from the dealer to see what remedy Yamaha might have.

as svrider.....loosen pinchbolts,pump the forks a few times and it should centre itself.

Have the same issue. Been keeping an eye on it and have been able to insert a 0.2mm feeler guage between caliper and disc. However, recently saw some metal shavings there and not able to insert feeler guage. Removed caliper and in the second photo you may see slight scrape marks on the caliper. 

Replaced caliper, loosened axle pinch bolts and pumped forks. Can now fit 0.2 mm feeler guage in gap. Have not ridden bike yet. 

It's obviously not right and I will talk to dealer about it. I expect Yamaha are aware of the issue,but how common it is I have no idea. Presumably as long as there is any gap at all there is not a problem, but I would prefer that the caliper was more 'centered' on the disc.

So I've also got the same problem.  I loosened the bolts and tried to recenter, but no luck.  I am either too late and now one side is too low, or it's a warranty issue.  Anyone else have a solution?

@wookee I haven't personally needed to do this, but the Yamaha service manager I took mine to for a quick assessment,  said he's used washers to shim the caliler closer to center the disc rotor.  Adequate thread engagement would be my main concern, with longer mounting bolts probably going to be needed.  Personally if mine wouldn't have created an acceptable gap after loosening and re-torquing the front axle, I'd be scheduling a warranty service appointment vs trying to shim the caliper.

I saw this thread and took a look at my T700 with 6000 miles on it.  I've never removed the front wheel and found the inside of the right caliper  to be about .005 thousands from the inside of the rotor as described above.  There was no rubbing or damage to the rotor.   My left caliper and rotor were centered.  I loosened the fork pinch bolts and pumped the forks with no obvious change.  So, I barely snugged up the pinch bolts and lightly tapped the right lower fork leg with a rubber mallet to center the caliper and both sides of the caliper so they  are at least .015 thousands from the rotor.  I will likely install some thin washers between the caliper and fork leg when the front tire gets replaced.  They forks did not appear to be binding after centering the caliper.

 

A shim .010 thick will not require longer caliper mounting bolts.

Just had a look at mine. Right hand calliper is also  rubbing. Front wheel has never been off. will try the pinch bolt trick and see if that helps tomorrow.

That's what fixed mine. It floats on the right side and if it's off just a tad it pushes the fork over a couple millimeters. Mine is fine now.

Same issue on my bike, pinch bolt thing didn't work, called the dealer to discuss, they asked me to bring the bike in for a photo and they will see what Yamaha Australia have to say about it.

There are a couple of key points about aligning the forks and the calipers in this video. I haven't tried this method yet but it seems more thorough than how I've done it up to now.

After reading what has been posted here and consulting the workshop manual and a bit of head scratching I have solved my issue with the alignment and rubbing.

 

At first attempt I loosened off the pinch bolts and axel, gave it a few shoves on the handle bars, tightened the axel up by hand and then the pinch bolts. = Bugger still rubbing.

 

Second attempt I read the workshop manual first. and noted inside pinch bolt first then outside. Result, made a little improvement but still not lined up properly.

 

I went back scratched my head and decided to do it exactly as the manual states and found the axel was being done up way too tight by my handometer.

 

So I;

 

1. loosened the pinch bolts and axel off

2. Give the front end a good few shoves and compressed the forks up and down a few times

3. Tightened axel to the required 72NM with a torque wrench and not with my Handometer

4. Tightened the inside pinch bolt first 21NM then the outside (Tighten to 21NM straight away do not partially tighten then torque down).

 

 Result = No more rubbing and calliper is aligned central again.

Hmmm, I wasn't that thorough, I'll give it another shot.

Same problem. @rumrum method fixed it. 1506 miles on mine. Slight rotor and caliper wear. Gonna let it ride.

Got some joy with a bit more effort!

I don't have a 1/2 drv torque wrench, so I just didn't go so hard on the axle this time and disc clears the caliper, still not centred but a lot better, that's another beer I owe rumrum.
