New BMW C 650 GT with 500 km. on it. About a month and a half ago the rear brake reservoir cap vibrated off on the freeway, never to be seen again. Ordered new from BMW. Took a month to come in, but no plastic seal. My scoot has the aluminum cover, a plastic insert under the cap, and a rubber diaphragm. The local dealer says his schematic shows no such plastic cap. Took off my right (front) brake reservoir and there was a plastic cap that assisted the seal. Informed the dealer that my still leaks like a sieve with out the cap. Took the cap off the right brake reservoir and installed it on the left reservoir. Problem solved. Accept now the right (front) brake reservoir leaks like mad. The dealer claims that there is no such plastic seal and doesn't know why mine had them. Its leaking bad enough that I lose half my fluid as shown on the reservoir glass in about 50 km. Any ideas out there? Really need some help.
