no, there'd be no way for you to stop in the event you went off roading.

No, you can not. The manaul I think states you must have a rear brake.

Whether you use it or not is your choice.

ok honestly this is beyond embarassing

sticky comes over yesterday to help me install a steering damper, and i tell him how the rear ss line i installed got shredded somehow probably because i didnt route it correctly

he mentions something about how he hopes the rear caliper is ok, and i sort of shrug it off...

fast forward to today when i start prepping the bike and notice there isnt even a freaking caliper there... i lost it sometime sunday at autobahn south (guessing the mounting bolts backed out from improper torque) but it didnt really even occur to me to check if the caliper was still there... as stupid as it may sound

i even had a couple grass excursions that day... which is when im guessing it got jarred off, but i never crashed or anything

i wouldnt believe it myself if it hadnt happened to me, gotta start safety wiring everything i think, no doubts in my mind

I don't think you read correctly, the bike was teched at the beginning of the day, I had a rear caliper at the beginning of the day.

I think I lost it riding around the track because I see no other way for it to have come off.

I went into the grass a couple times, but didn't even feel the need to use rear brake, letting off the throttle and coasting to a slow speed worked fine.

And I'm in B... so is this somehow forgivable if I'm A or something?

It was completely my fault the bike was in the condition it was in, it wasn't stupidity on my part but carelessness really. I took the rear caliper off earlier last week to check the pad wear back there and put on the rear SS line, and I guess that's all where it went wrong when I didn't retorque properly.

Not like there is anything wrong with the bike besides a lack of torque...

WOW, I've never heard of anyone come back to their bike after a track day and not have a caliper anymore that is fuckin great! Sucks though, hope you can get it resolved before your next track day.

Inspect your bike between sessions, give everything a wiggle.



Tom




Glad it turned out OK..... best case.



Worst case ? The caliper Jams in the rear whell when it falls off you have a
crash and then get ass-packed by three other riders. Three of you go to hospital.
The other dies on site and you won't ever need to worry about typing with your
right hand again.



By a torque wrench, pay attention.

And I'm in B... so is this somehow forgivable if I'm A or something?
I think the point he was trying to get at is that at B pace, many feel there is very little reason to either crash or run off the track (although it does happen). I know that you crashed at Autobahn North as well. Perhaps there needs to be a little more attention paid to line and form, or whatever is causing you to sepend so much time off the track.

At A pace, the rider knows the line, and has "proper" form, which may mean somethign different to each rider. At A pace, it is more likely to have an off-track excursion do to traffic, passing, pushing too hard, and/or going beyond the traction limit of the tires, etc...

It is no more "forgivable" in any class, just less expected in B than in any other class IMHO.

Since your bike did not seem to hit the ground, it wasn't necessary for you to "re-Tech". As such, it wouldn't be expected to have parts falling off. Anytime that wheels are removed, it is necessary to check all of the bolts, axle and keepers (if any) especially on calipers. Having them fall off is actually a fairly common mistake. One of my first track weekends, a guy at Putnam ran straight off in front of me going into T9... his right front caliper was hanging by the SS brake line... he didn't tighten the bolts properly.

No worries about, Chach. Glad about three things, one, you aren't hurt. Two, Nick looks like he can help you out, and three, you learned the lesson without crashing.

I have had a two crashes that were mechanical in nature, and two because I pushed tires that were beyond their usefulness at A pace. Personally, I would prefer to crash because I outrode the bike, not because I was ignorant or didn't know any better, or tech my bike well enough. Alas, I have 4 crashes for those reasons, and zero because I pushed the bike to hard.

Good luck with the new part, and hopefully, you double and triple check everything from now on. (I do, after learning the hard way).

See you out there on your next weekend with NESBA (as that is where I ride)

+1 with the safety wire. And always check your bike in between sessions.

I'm very glad you didnt' get hurt by trying to use the rear break and not having it. I'm also glad no one else got hurt from your FOD.

One other thing, if you lost your caliper wouldn't you have left a trail of brake fluid along the track from the exposed brake line?

Never a bad time to climb... unless the weather is really horrible, and then you climb inside!

Maybe this is why my rear caliper is held on by my axle wheel and swingarm. I'm curious too, how do you lose your caliper and not lose brake fluid all over the place.

He probably did lose it. At speed and given the small volume of fluid in the rear brake system, it would be hard to spot. If it flew off as soon as he went off course, the entire brake system would probably be empty by the time he got back on.

Having a track bike with 600 miles on it, I have an inherent preference for things being all nice and new on a bike that I am going to be doing consistent performance riding on.

What track day are you planning on doing though?

Maybe that was the slimey liquid I found all over the front of my bike that day. How do you just "LOSE" a caliper that is bolted on and attached to a brake line.

That could be bad if the fluid ran onto your rear tire.

+1 to what Tom said. I actually had a bike that was new to me. Tom came by and we chatted for a brief moment. He turned around when he walked away and said "Oh yea, your peg is loose." He then walked off. I was like yea, the "A" guys screwing with me again. Nope, my peg was a little bit loose. I just bought the bike and didn't didn't go over that rearset yet.

I safety wire the important parts. (Still have to do that to the new bike though). Everything gets some lock tite. Just the medium stuff so nothing vibrates loose. I was at a CCS race a few weeks ago when two bikes come down the hot pit. Both of them lost their shifter lever bolts.

Tom and Jason from Speedtech have taught me to check your bike and check it often. Do a quick tech of yourself atleast during lunch if not every other session. Check the front brake lever retaining bolt before every single time your headed out. Pilots preflight a plane before every flight.

Glad I notced it Greg..... although it was more than a little loose.

You ever see what a little brake fluid will do to a front fender ?

A few drops will fatigue it so bad that the fender can explode
at speed and come off the bike. brake fluid + bodywork = bad.

Dude are you serious?!

The previous owner could run circles around you on that bike (even without the caliper!).

Seems like an odd statement from someone that used to walk a TT around the track!

wink - your post was dually noted

fortunately, i learned what NOT to do when going off into the grass and doing the wrong thing at ABN, i grabbed front brake and paid for it

as to why ive been going off track, i think its a target fixation problem...

well, the first time i glanced too long at the track photog, and the second time i went into a corner too hot
