Re: Way off Ranger topic.
General rule of thumb is that if you replace 1 it is best to replace both. That is since when one the calipers has a problem it messes up the other one, such as in many cases if one caliper is sticking it can be the other side that has the problem. However, if neither is bad you should be ok to replace just one.
