Works Front Brake Cap

Recommended Posts

Something strange started happening. After a crash where the bike laid down for a half hour, my front reservoir went dry. I removed the cap back in the garage and filled and bled with new dot4, replaced the cap and with the steering turned left, brake fluid is leaking from the cap.

Looking at the cap it has channels cut into the rear of the cap that have to be allowing the reservoir to atmosphere, it just looks that way. There is no gasket seal, is there supposed to one? What is causing the fluid leak?

There should be a rubber bladder/seal under the cap.

Kawie dealer is an idiot, get an oem rubber seal and install under cap. Res may be alittle full if it is still topped off.  Have a rag handy when u put the cap on.
