I know what your thinkin."Don't be cheap,just have the old rotors turned it dont cost much".Yes i kinow this.Anyway does it really hurt anything to put new pads over the old rotors even if the rotors havent been turned.The rotors do NOT have any large grooves in them.They are still smooth.I just dont want to have to get back into tearing this truck down again because taking the old rotors off an 87 GMC v-1500 4x4 takes a special socket i do not have and i dont want to have to put new bearing seals in it too.Plus i dont have that much time.Just let me know what you think about using the old rotors without turing them and just using new brake pads.Thanks.

There are alot of good answers here,so i will let this question go to a vote.

no it doesnt, "unless" rorors are damaged or have fractures, "which I`m sure you would have checked"?
I have been replacing disc pads the same way for years.

It's not a matter of being cheap it just a matter of doing the job the right way the first time. Even though you may not see any grooves on the rotors they are warped and uneven. Because they wear over time the same way your brake pads do. If you don't turn the rotors and just install new pads then I will guarantee you within a few short weeks you will notice your brake pedal starting to pulsate. That's because your new pads wore themselves the same shape of your rotor. Hopefully it doesn't cost you too much to get them turned. Some parts stores are totally ridiculous. You can almost buy a new rotor for the price you pay to have the S.O.B. turned. Anyway hope this advice pointed you in the right direction.

it wont hurt anything the only thing it will do is maybe make your new pads wear down faster. Dont worry about it I always replace the pads without turning the rotor. In fact now that i think of it I dont think I have ever had a rotor turned I just wait until they get bad enough to replace. Depends on the vehicle but on my car the rotors are about $15 a piece and they get $7 to turn them and you have to wait an hour for them to get turned I just spend the extra money and get new ones.

If your rotors are in good shape it can be done. Just remember
there will be some break in period as the new pads seat into
the rotors. If your rotors are grooved the new pads can not
make full contact. Reducing the brake surface reduces braking
efficiency. So if you rotors are like this ^^^^^^^^^^^ and you new
pads are like ----------- you should machine or replace them.
Remember its cheaper to do it right the first time. Than having to
do the same job twice.
PS Remember it is hard to put a price on life so be safe. They
are you brakes after all.

Assuming they are smooth, without any warping, and still thick enough, machining the rotors will only help the seating process. To replicate this for your application without turning them, take some large grit sandpaper and scuff the front and back of the rotors in a zig-zag pattern. Thatll help the two surfaces mate together, giving you much better brakes. Also, when you get done, do a few quick panic stops (preferably on a side road or in an empty parking lot). Thatll help them to seat much quickly.

You won't have full braking efficiency until the new pads wear into the grooved disc. Try a soft pad material.

I heard it would start new grooves in the pad. If they aren't that deep, I don't think it's a big factor, but depends on the depth of the groove.

No I don't think so, my husband has to change his brakes quite often, and he doesn't turn or change the rotors.

I would want to repack the bearings though, if not done in a while, but I have plenty of rags, grease, and the special socket.

If thje rotors are smooth it's a waste of money to have them turned!!
