It is not unreasonable to do so. Most brake manufacturers would probably agree. However, you may have the rotors turned in order to provide a smooth surface. So to answer your question, It isnt always necessary but he isnt trying to tke you for a ride.

Most of the answers here are correct. Next time, ask to see your old rotors or ask them to save the old rotors. If the old rotors are smooth and you see no grooves or deformities, and they suggested to replace the rotors, find a new mechanic. Make sure the mechanic doesn't overtighten (use an impact wrench) the lug nuts on your wheels. If they do, you have a much higher chance of ending up with warped rotors, particularly if you drive an Asian or European car with relatively low torque specs. If this happens, then your steering wheel will start vibrating excessively when you brake. Then you will need new rotors the next time you get new brake pads. Avoid mechanics who cause these problems. Most don't do it on purpose - they use an impact wrench without a torque limiter to save time, not knowing about the damage they can cause (on imports, usually).

you are supposed to turn the rotors everytime you replace pads so the pads can seat properly to the rotor. You usually only replace the rotor if it is warped or past its turning life. Usually you only turn a rotor once. I rarely ever turn my rotors though. If you dont wear the pad down to the metal, the rotor should be smooth enough to just throw pads on. But shops usually turn the rotors as a part of their service.

That shouldn't be necessary every time. Unless you wear the pads down to the rivets or backing plate and groove the rotors. Most rotors can be turned on a lathe once, unless they are so warped that they can't be machined without going below the minimum thickness required for safe operation of the brakes. good luck.

unless you take the pads down to metal to metal or grinding everytime you shouldnt need to replace them everytime .brake rotors can be machined within allowable specs.you can only do this a couple of times to a rotor before it has to be replaced.sounds like your getting ripped off time to find another shop

hes just trying to get more money.if your rotors are still good,then you dont have to replace them everytime you change pads. i replaced alot of pads and i didnt replace the rotors,unless they were bad,like grooves cut in them or low spots on them.if your rotors are good,then all you have to do is sand the rotors a little and replace the pads.

Because they make more money if they sell you new rotors than if they simply grind the old ones to a flat surface again. Find a friend good with cars to do it for less money or even better fix them yourself. Brakes are actually really easy to fix. I dont fix my own as i dont have much time on my hands but my neighbor fixes them for almost 1/3 as much as most mechanics will and he doesnt recommend me to have 2000 in repairs done that i dont need. Beware of mechanics they do sell you things you dont need, most work on commission these days, places to avoid include valvoline- cheap oil changes but they try to sell you wipers, air filters, and recommend things you dont need and they dont even have a formal education in mechanic stuff, other places to avoid include monroe and good year. Monroe is a good place to get your muffler fixed and valvoline is a good place to get your oil changed and good year is a good place to get tires but get just what you intend on getting before you arrive and dont let them talk you into having other repairs done. Most commercial mechanics have no morals and will be the first peope you meet if you ever get to visit Hell. However some of the small garage mechanics provide excellent service, give you what you actually need and are usually willing to help out with temporary fixes if you are tight on money. So screw all the chain mechanic stores they suck!!!

maybe your rotor isn't smooth or it might be they get paid by commision so that would be more money for them.
