I decided to replace the hoses on the front because my daughter will be driving the truck and I want to make sure she can stop and the hoses are 38 years old (as far as I know). When I went to look it wants to know which size REAR brakes (11" or 11-5/32") the truck has before I can pick the front hoses. I thought this odd but remembered that there are 2 different front brakes, which would make more send. I have the 1" thick rotors, does this correspond to a certain rear brake? I would think the 11" but I know how engineers can be. Thanks!
