The original master cyl. is real easy to rebuild & the kit is not expensive. You will need to buy a brake cyl. hone. They are available at the Chinese tool stores for less then $10. Make shure there are no deep corrosion in the bore. A small amount will hone out & a slight discoloration is acceptable. If it won,t clean up you will need to buy a new one or get it sleeved. It is best to bench bleed it & get some Speedy bleeders.
