What's that bar do?

[itchybro]

Neat torque arm daymare thread over at pelican site. Make me think I may not want that shorter arm for awhile.

I followed it to the braking nightmare making me think even more that I don't want to linked brakes. That bar provides the second arm of the parallelogram that is your rear suspension.--Jerry

Yuck! That looks like no fun. As long as the rear wheel didn't lock up (ie, binding u-joint, bottoming out), and the rider didn't freak out, it wouldn't be too hard to control. The bearings are still intact and braking wouldn't be affected due to the already collapsed nature of the FD.

 

On the other hand, if it happened in a tight turn...

Looks like Oprah Hazzard has been at it on other sites as well. The sky is falling! The sky is falling! Jeeeeeeeeeese!

I wouldn't say the sky is falling but as a nuclear engineer, I don't like safety systems that are single failure vulnerable--even if failure is very unlikely. I like my old, direct acting ABS brakes. As I shop for future bikes, this will be a negative on the side of the BMW. --Jerry

'Bout time we have a decent avatar of Shawn. Good lookin' guy like that got to 'spread the news'.

Ayup. Look at his choice of words and his references to the Continental-Teves system, and that's definitely him.

 

As far as the Paralever arm...I don't remember the technical name for it, but the hexnuts that go on the bolts that hold the swingarm in place - those nuts are slightly squashed from side to side, providing more friction than Nylock nuts, maybe even more than Blue Loctite. Something went seriously wrong if that's what backed out on the guy. Not only that, but the nut backed out, AND THEN the bolt danced its way out of the hole.

 

It's the first time I've heard of this happening. It was the shorter torque arm, so I wonder if it was an aftermarket change, and he used different nuts (or eschewed a torque wrench).

I don't know if it's a technical name or not, but in the automotive industry we refer to those as crimp nuts. Please, no visuals needed!

I thought that those nuts were "one time use" only... Meaning, when you remove them, you have to replace 'em w/ new. Could it be that the nut was reused and no longer had the (for lack of a better term) crimp strength to it?

There's nothing in the manual about replacing those nuts, either on the Paralever arm or on the shocks (which use the same type of nut).

Well, there might be a more technical term for it but in the airline industry we refer to those nuts as self locking. They are reuseable if you cannot thread the bolt through the nut with your fingers.
