So both of my rear calipers are dead . Im just wondering whats my best option in this case ? buy after market , or rebuild those ? if buy after market what brand ? and what to stay away from ? Im broke now so just trying to say away from spending too much

 

Dead as in seized up, leaking, or what?

Wouldn't even bother trying to rebuild them, personally. You could get a set from a junkyard, or just grab a set of aftermarket calipers. AZ has them for ~$80, but other auto parts stores may have better prices.
