why does my 01 tahoe use up rear brake pads so quickly 92k miles on car and never replaced front pa

Could be, or could be bad rotors or a sticking caliper.

your e-brake cable could be adjusted too tight

the pad is too small for the size of the vehicle Gm fixed this problem in 06 they switched back to drums on the rear. maybe try a ceramic pad it might last longer

92 K is a lot of miles on the front pads. If your on gravel or dirt, try a controlled panic stop and see which tires lock up first. If your front breaks don't lock up first, it may be a proportioning valve.
