2005 Suburban
270k
Absolutely base (purchased with no options or packages)

I need about another 150k out of this ride.

I'm starting to get pull on the front brakes, sometimes severe. Should I be thinking about the calipers?

Better to purchase reman or rebuild? If reman, who would you recommend?

Is this something I ought to just do anyway, given age and mileage?

How do I measure the rotors to see if they need replacing?

What else ought I be thinking about to try to extend the life on this one? Just had to have the fuel sender unit replaced. Put new plugs and wires in at about 180. New shocks at about 220.

Thanks
