Repairing Master Cylinder

How hard is it to repair the master cylinder? my nissan hardbody master cylinder went, and cnat find a used one.. and new ones are abot 80$ info needed..

do you know whats wrong with it? i know some rebuild kits (seals etc.) will end up costing more than 80$..

Look on eBay. Last one I bought was under $30 shipped.

just buy a new one.

roughly 98% of the time, it will cost exactly the same to rebuild the hydraulic part than to buy a new one. plus, if you buy a new one, you can usually get a warranty

I would go with a new one
