A young rider friend of mine has ended up with a knee like a melon after cresting a berm following rear brake failure on his KTM 04 125SX. It appears the seal inside the master cylinder was bad, so when he was braking it was putting the reservoir side of the system under pressure, and eventually blew the fluid level sight glass out of the wall of the master cylinder resulting in loss of fluid and total brake failure.

Has anyone had this fault , and if yes are there any mods or aftermarket kits to avoid in future, thanks Sully.

I have heard of this happening to one other person on a 03. I dont think there is any after market stuff available, but KTM makes a repair kit for the master clyinder for about $30. Otherwise if you need the whole master its about $130.
