New SRAM hydro brakes out by April

[mvrider]

So, it took them 3 years and 2 winters to develop the recalled version. How could their customers trust the new version that's rushed to market?

incremental versus ground zero development

Bike radar has some quotes I found alarming:

Three types of hardware concerns lead to the late-December recall, which affects both HydroR rim and disc brakes: the bleed port, the piston assembly, and the master cylinder.

There wasn't one major concern, there were three???

"In the winters of 2011, 2012 and most of 2013 we did not encounter problems," Day said. "We were very comfortable that we were testing widely in the environments that the product would be used in. So we were as surprised as anyone when it manifested on December 7."

Extensive testing was done in the lab and in the field, Day said.

"There were some small changes from pre-production to production products and it was in those adjustments that the problem came," Day said.

So they extensively tested one product, made changes, sold the (untested?) revision, and then were surprised when it failed?

Now SRAM has put an environmental chamber into use as part of its testing regiment. "It wasn’t a tool that we had used in development," Day said. "We thought field testing was adequate. The weekend after the (Dec. 7) failure we began using that tool, to begin digging into the cause. One of the things historically that we found is that laboratory testing is very important but you can’t test for everything in a lab. We thought we were covered; we weren’t covered."

Hey sram, before you go electric:
