Difference between back and front brakes

Since you got the vehicle with most of it’s mileage on it . . . 135,000 of it’s 149,000 . . . you can’t assume that the previous driver drives like you. If you’ve never replaced a set of back brakes, that doesn’t mean that you won’t have to do it for the previous driver. My wife is on her 3rd set of front pads, 2nd set of rotors on our 2010 Civic, only 35,000 miles. I don’t even talk to her about her driving style anymore, not worth the argument. Some folks drive with one foot on the gas, the other on the brake . . . and you can be sure that something will wear-out faster that way. If you trust the mechanic who recommended the brake job, get it done. If not, get a 2nd opinion. The price seems reasonable, as others have pointed-out . . back brakes are not hard to replace, they just take a lot more (shop) time due to their design. Good luck! Rocketman
