My 2003 Acura MDX makes noise while going down the slope with brakes. Mechanic told me brake pads of rear wheel are worn out and that's why it's making grinding noise sometimes. He is also asking me to resurface the rotor. Is it necessary to resurface the rotor while replacing brake pads.

If it's at the point of grinding, yes.

It is only necessary to resurface the rotors if the pad/shoe has worn down so far that it has cut into the rotor. You can tell if this has happened by running your fingertips over the rotor top to bottom (don't try this right after you've driven it let the brakes cool off ). If you can feel grooves in the rotor then you will need them turned. It is not necessary to turn rotors every time you replace your pads.

If you have had metal to metal contact then I suggest you have your rotors resurfaced or replaced if they have been resurfaced before . Most cases they only remove a small amount of metal to accomplish this. With simi-metallic pads you get more rotor wear so again it is probably a good idea to have this done. But on the other hand I have replace pads and skipped truing the rotors and had no problems..It all depends on the condition of the rotor. Bear in mind most brake shops will insist they true the rotors even if they are in excellent condition.... its money in their pocket..

The grooves in your rotors will put grooves in your pads. Change the rotors. There are three prices of rotors .The cheapest are the two year guarantee also called throw aways . They are good and better than grooved rotors.Turned down rotors will warp because the heat transfer in the rotor is changed with less metal.That is why front rotors have the Finns in the middle. The cost of turning them down is about the cost of the less expensive rotors

Depends how bad and how long you let it grate.
When the pads wear down so some metal is touching the rotor (making the grating noise) you risk scratching the rotor, if that has happened then wear and tear on your next set of pads will be very VERY rapid.

the proper way is to resurface the rotors every time you do a brake job to get the optimum brake performance but it can be done without resurfacing them.

Not unless the rotors are scored from the worn brake shoes.

djs above is correct, it's just as cheap to buy new rotors as it is to turn them down. Personally I'd get new rotors because you have less chance of warping.
Disk breaks are really easy to replace, if you can change a tire you can probably replace them yourself and probably save about $200 bucks.

usually if the rotors are warped then they need to be resurfaced that is common maintanance when changing your brake pads

I have the same question...thought No for resurface rotors...but will see what experts have to say
