I would highly recommend it. My front driver side caliper locked up about a year ago, and every time i would brake, it would dangerously cut to the right, immediately. I replaced the caliper without a problem, and two days later the left one locked up, and i had to wait two more days for the caliper to come in the mail...So i learned my lesson, replace in pairs to avoid the trouble!
