Standard vs Silicone Fluid?

It was recommended to me by a fellow rider who also services bikes that silicon brake fluid is alot easier on rubber components within a brake or hydraulic clutch system. Would this extend the life of the hydraulic clutch components?

Possible. To try it though you have to absolutely remove ALL traces of the standard DOT 4 fluid in the circuit first, which means disassembly of the master and slave cylinders, cleaning them thoroughly, blowing the lines clear and flushing them with DOT 5, then re-filling with DOT 5.

The two fluids are not compatible.

I don't see any reason other than that to not do it since the clutch system is simple. I certainly would not try to do the brake systems though.

I don't want to achieve immortality through my work...I want to achieve it through not dying.

No bike now, but maybe in the future.

Just remember dot 5 is NOT authorized to be used in a BMW motorcycle...

The dot 4 is all you really need..............Regards Pete
