On the top of the reservoir cap there is a little rubber dome. Under the little rubber piece is where a little washer on the level sensor float contacts the two electric pins. However the little rubber dome ontop of my fluid reservoir cap keeps coming off and i dont want dirt etc to fall into the brake fluid. Is something ment to hold this little rubber dome down?
