only 4% might catch fire lockup and launch the rider like superman? if the new improved replacement part was $100 I would agree just kill off a few riders and passengers ok but the part is only $36 thats a harder sell
My DLP list shows the secondary master cylinder
complete is available @ M/CYL ASSY., SECOND 45600-MCC-016 001 $90.64(retail)
$68.79 (DLP price).
Parts must now come from Japan! That would make it approximately $8,667,540, just for parts, which doesn't include the horrendous cost of shipping to dealers and labor to install.
Moot point on price difference. Surely not a hard sell in anybodies mind to only replace those that fail.
I still maintain, if one's rear brake drags enough for heat generated to start a fire and one can not detect that, one should not be riding!
Another moot point, as I understand what you're saying but, a rear brake locking up will not launch you like superman. It will cause, most likely, the rear to slide out from under you, dumping you on the road for at least a good dose of road rash or much worse.
There has been no official word as to whether this failure mode can manifest itself after years and miles of faultless service or if it's a bad one when the brake drag starts or how long/miles it takes to reach the danger point. Having said that, I would be riding only the miles it takes to get it to a dealer for the check and no further!
Ride safe
