Front master cylinder failure

Recommended Posts

Just a heads up.

This morning I had a catastrophic failure of the front master cylinder. It gave no warning. No fade or slow leak down. Just nothing. It worked just fine at one stoplight. Completely failed at the next. Puked brake fluid all over the fuel tank.

Rode it to my dealer using the rear brake, it's under warranty and will be taken care of.  That's the good news. Bad news is, it's on extended back order. 

I was supposed to meet my son in Murphysboro next week and ride to NC for a few days of fun.  

😡🤬

Whoa! That is a dangerous failure to have! Glad you didn't end up having to ditch the bike or something. Luckily haven't heard of another failure of this sort so hopefully that is an indication that it is very rare.

Hope you get back on the road soon.

@fddriver2 - Do you know what exactly failed on the master cylinder?  For it to be spraying fluid and go dead instantly, I assume some sort of catastrophic failure 

Glad you’re ok & hope it’s resolved soon.

Looks like an FJR, Concourse, and Huyabusa all had a little too much to drink one night...

Probably uses the same master cylinder.... hahaha. (I have no idea.... just being funny)

 

Edit.... I believe they are the same except for the resevoir. The sub assembly has different part numbers (assuming due to the different resevoir) but if you look piece by piece the part numbers are all the same.

@texscottyd It looks like the seal around the plunger failed. It wasn't seeping or anything. Brakes at one stoplight. Zippo at the next. brake leaver pulled all the way to the handlebar. 😑
