This should really get the purists here all wound up…
The caps on my brake/clutch reservoirs have given up the ghost. After ~22 years, the VERY thin aluminum “screw” part of the caps has literally just about turned to dust, so they barely screw onto the bottles, and the whole plastic/aluminum float assemblies are no longer connected to the screw caps. Amazingly, the float assemblies and plastic parts appear to be just fine. But, given that the “correct” replacement bottles/caps available STILL seem to be quite expensive, and of marginal quality at best, I’m seriously thinking of forgoing originality, and replacing them with something far cheaper, far more functional, and more readily available. I came across these:
Being an old BMW guy, this has a certain attraction. This one bottle provides fluid for both brake masters, and the clutch master. It is baffled, so the two brake masters each have their own fluid reserve, and the clutch connection comes off nearer the top of the bottle, so, while a brake leak will starve the clutch, a clutch leak cannot put the brakes at risk. A single float switch covers all three systems.
