Brake vs Clutch fluid reservoirs

Hey guys,

Quick and probably obvious question: Is there any difference between the clutch fluid reservoir and the front brake fluid reservoir?

Could i theoretically replace them both with identical universal reservoirs (eyeballing the plain ones, as my current ones are corroded & ratty as balls)

As you noticed the clutch one is smaller and they contain different fluid but besides that anything that fits and works with the hose size will do!

Cheers guys, Much appreciated!
