Review on Cardone 10 1863 Remanufactured Master Cylinder by Quinton King

Bought this master cylinder for my SUV. Went to install, removed tank cap and found full of heavy rust. The outside has some light surface rust which is common as they cannot be painted. However, the inside is important, and the inside is full of rust. BAD BAD BAD. Poor quality parts and questionable sellers seem to be the norm for Revain.
