Does this brake disc need to be replaced?

[limey]

Put bike on centerstand , start it , take find sandpaper and to the serfice ,, clean then rotor , new pads .... that's the way i woud have Done it

That's a bit dangerous, I'd be turning it by hand or leave it alone.

Thanks, AV Geek. I checked Rocky Mountain (I do a lot of shopping there and they're great), but the only rotor I found for the S10 was a Galfer. They only had aftermarket brake pads, too.

Bike Bandit seems to be about 50-50 on bad reviews for customer service. Naturally there is probably a bias there, but the complaints seem to revolve around orders that take far longer to ship than promised, showing parts as available on line when in fact they aren't, and hidden shipping/handling costs. Fortunately, I apparently won't need a rotor immediately, so a delay in getting one won't cause a whole lot of problems.

LOL, I feel like a dork quoting myself, but for anyone following this thread, I was wrong about Rocky Mountain ATV not having OEM parts. I missed that entire section of their website where they stock OEM stuff, so I did them a disservice by being uninformed. They do stock OEM parts for the S10, and at a decent discount too. So, once again, hats off to Rocky Mountain.

I have a service manual. The issue isn't the thickness or runout of the disc; I was more concerned with whether there appeared to be enough surface damage to the disc to warrant a replacement. The service manual doesn't go into specifics about that.

I don't think I would be worried so much about the surface damage or the way it looks. I use mine for a lot of off road and it looked a lot worse than yours, I actually just replaced the rear at 100,000 km just because it was under tolerance.

Hey RC, I think most rear discs will eventually become scored, my 2012 was really bad, but the thickness was good, it bothered me, so I changed the pads with organic version, saw no improvement in performance or lack thereof. Spoke to a few other riders that had same issue on GS's, seems it is more common than you expect. Change the pads, be done with it.
I would be more concerned if it were the front discs.... just my humble opinion.

Thanks Limey. I've decided to just put the new EBC pads on and run it like it is, and keep an eye on the pad wear. If the braking feels compromised after the break in period, or it's too noisy, I'll just replace the rotor and go back to OEM pads. If all is good, I'll probably run the EBC pads until they wear out, and then replace the pads and rotor. I don't know how long the EBC pads last, but I was getting 15,000 miles or so out of a set of OEM pads. If I even get half that out of the EBC's, then the rotor will have almost 40,000 miles on it and will probably be due for replacement anyway.

I definitely now believe the reports that the Super Teneres are really hard on the rear brakes. My front brakes have just shy of 14,000 miles on them, and they look great. I managed to wear the rear pads down to the metal in just 15000 miles. The previous set had 15,000 miles on them when I changed them, and they were pretty worn out too (but not as bad as the current set). I suppose that's a byproduct of the linked brake system. Lesson learned, though; I'll definitely keep a better eye on them in the future.

 

[RCinNC]

Hey, Dogdaze, how ya doin'? Yeah, I'm just going to wing it for now and just put on the new pads. In the meanwhile I'm going to have to buy a micrometer so I can check the rotor thickness and keep an eye on it. This was one of those issues I've never encountered before, so I really wasn't sure what a rotor damaged beyond use would look like.

You have to remember, they are linked brakes when you activate the fronts first. If the rears are activated first, they are separate. Hats off to Yamaha for doing that!! It allows more control when doing slow, tight, moves. Like bar lock turns. Linked brakes were designed for inexperienced riders. I believe that Yamaha knew that the TENERE was not a bike that first time riders were going to be interested in.

 

[RCinNC]

Yeah, I knew that. I rarely use the rear brake alone, unless I'm doing the slow speed maneuvers like you described, or maybe scrubbing off some speed before a curve. I'm not an inexperienced rider (almost 40 years now), but be that as it may, I like linked brakes, though they took some getting used to.

My only complaint with these fantastic linked brakes is I have been brainwashed by them.
I have to remind myself on other bikes that my right foot needs to be more active in braking decisions.

I had ABS on my V-Strom, and now ABS, linked brakes, and traction control on my Super Tenere. I think if I went back to my old non-ABS HD Road King, I'd probably high-side it before I got out of my cul-de-sac .........

That's how I am with ABS. I get on my FJ, and have to remind myself that I have to think about hard braking. I've actually had guys tell me that they can stop quicker/shorter without ABS. When grandma pulls out in front of you....on wet pavement....start thanking the ABS gods!!

 

[Dogdaze]

Hi RC, I'm good thanks, busy with mundane life issues, have not ridden in over a month, snow, ice etc.....
I hope this settles your mind about the disc, as long as it's not warped or below thickness level............ just ride it................ in between making add-ons for us to copy ::008::

Lately I've been working on some custom made gunbelts and holsters, so the Super Ten projects (like the modifications to my cell phone case) have gone on the back burner for a bit.

It was 2011 and I had just gotten my PDP Tenere. I immediately took off for a multi-thousand mile ride with nary a plan or itinerary. Found myself in Arkansas heading back home from "the dragon" and it was raining pretty good. But I had bonded with the machine (on the dragon) and was at a pretty good clip when I HUGE deer ran right out in front of me. Honestly, I didn't have time to think ABS. I just grabbed a hand full of everything I could get.

STUNNED me! After 40+ years of riding, I had never experienced such an amazingly composed halt in the middle of the road.

Made me a believer from that moment on. And it might be the beginning of my cheerleader approach to this machine over all these years.
I'm unabashedly a Tenere fan for so many reasons. I have explored its strengths and weaknesses in what I believe is a thorough manner.
It's brakes are just one thing I am continuously pleased with.

 

[RCinNC]

It would come in handy if the bike came equipped with an easy way to disable the ABS for those occasions in dirt/gravel when ABS is actually a hindrance. With that said, though, I think ABS on motorcycles is one of the best innovations to come along in years, and I've been a true believer ever since someone pulled out in front of me at an intersection while I was riding my V-Strom. Those ABS brakes were good, but the linked ABS system on the S10 is so much better.

 

[Mark R.]

An ABS off switch is easy to install. I have one, and it is absolutely vital for off road riding, IMHO.

[RCinNC]

Yeah, I know there are aftermarket solutions; I just think that a bike that's designed for the type of riding that the S10 is, should come with a switch to disable the ABS as a piece of standard equipment.

 

[Mark R.]

Agreed.

 

[Sierra1]

On my Jeep, when put in 4-lo, all the electronic nannies are turned off. I'm kinda surprised that on the Tenere, when the traction control is turned off, the ABS doesn't get turned off also. In a manner of speaking, they're different sides of the same coin. Like the Jeep, it's just programming.

 

[snakebitten]

I suspect that if it did have an ABS defeat button I would defeat it at times offroad. But having said that, with a fair amount of serious off roading, especially for a HUGE dirt bike, I've not been punished by it being on much. On the contrary, it's almost always impressed me with its dirt stopping savvy.

If it really drove me nuts, or severely hampered my riding I'd just go through the effort to defeat it.
The fact that so few have equipped their Tenere with a defeat button says a lot.
Many of those same bikes are farkled up pretty nicely. That button isn't difficult to add.

Could just mean I don't charge as hard as I sometimes think? Lol
