Hen Brake Pads 2009


H.e.n. bikes

Recommended Posts

Because every time a new HEN product comes out I only ever seem to have negative comments. For this one it's basically poor finish and limited recess for the pad to sit in. Heatsink ftw in my opinion...

Have to agree with dave, to be honest.

Are they some christmas cracker version?? :-

While seemingly a simple and practical way of dealing with mounting....... we found (Plazmatic CR pads,circa '99) that the stresses put on the slave nipple when pads were not adjusted to be close to the rim were........well, negetive in effect...........broke the nipples. And I hate it when my nipples are broken.

I am not a fan of the 'O ring' mounting on any CNC backings, but surely the issues you found with the Plaz backings was down to their shape, not the fact they were mounted with an O ring?

Doesn't the O ring reduce the chances of the backings snapping the tabs (that hold the brake pad in place) on the slave pistons?

Yes, it was not the "O" ring itself that was the problem..........sort of.

The "O" ring does not really absorb that much force as it is pretty small. Using an "O" ring that is larger to try and compensate only gets you a pad that mushes around too much. The mounting area needs to have sufficient flexibility to diffuse forces from the nipple. The trick of course is that the pad at the same time remain well enough connected to the lever for accurate feedback/feel.

I admit, that of the thousands of CRs we made, there really were not that many that had slave cylinder issues. The above concern really only reared its head when the brakes were set up so the slave cylinder had to really extend itself out before pad hit rim.

Woah woah woah Adam, slow down, you're forgetting Tim is always right!

Always right?.... most certainly not. I am not sure in this instance relating bits of historical observation has much to do with self ascribed omnipotence.

Only issue I had with CRMs was that, at one stage, I had 13 pads that were out of their backings because they just weren't glued in all that well, which was disappointing for a pad of that price.

There was a couple batches where the glue was an issue. For those that made the effort to contact, I replaced them without question. If I had anymore, I would mail them to you......... sorry about that.
