Well I must state that at 79,000 miles I had the front brakes done. I now am going to have the rears done at 90,000.

My question is should I buy new rotors or just have them turned? My fronts squeak sometimes, not too bad and were turned. I do tow a boat about 50 times a year.

 

Seeing as it is your first job i would think the rotors should be ok. Check the minimum run-out, if their ok just have them resurfaced. Ocassional squeaking brakes doesn't mean you have a problem unless it's excessive and/or consistant

 

x2 what Dave said. Measure the thickness with a digital caliper ($10 from Harborfreight). Replace it if the thickness is less than 1.417".
