I have a 2012 grand sport convertible 27,000 miles putting new brake pads brakes are squeaking is it necessary to change the rotors to or can I just clean dust out of the holes

 

As long as yours have no grooves or abnormal wear,just clean them and reinstall.No need to replace them.They aren't too expensive if you decide to go with new ones.

 

With the mileage, and the fact that the OEM pad-lets are/where HD's that are more aggressive, would pull the rotors to have them turned, to flush the two surfaces to each other. Hence rotors wear faster on the outer edges, then the hub edges, and new pads on the less then parallel rotor surfaces to each other, means more pad wear until they do mate in with the rotors surface. Check around, but locale shop near me, only charges $15 per drilled rotor to turn them to square them back up.


As for pads, would pull them to take a look at how much life is left on them, and if still have some life, problem with the squeaking is the dry metal parts of the pads to the metal parts of the calipers/having the brake silicone grease washed away from all the car washes.


So you never want to get silicone brake grease on the rotor surfaces, nor on the pad part that will contact the rotors, but the metal to metal part of the pad to calibers, need to be lightly coated with silicone Brake grease so you don't have the dry metal against dry metal that will cause the squealing problems.


Also, little bit of silicone brake grease to the anti squeal shims as well (to cross pins and to sides of pad-let metal backer plate edges].

 

I wouldn't put new pads on without turning the rotors.

 

That's a very good point ... but I think there are not many places that still turn rotors.

Maybe I'm wrong, but that's what I am led to believe.

 

ORiley Auto Parts does them, but I am not sure they are everywhere.

 

You also need to find out if the guy who turns them, has had previous experience turning drilled and or slotted rotors. It's a different skill level than plain rotors.

 

In my case, I gave up on trying to find someone that will properly re-surface (turn) my rotors ... I just ordered new ones

 

Not to mention getting rotors resurfaced is a huge pain in the ***. With new rotors you can do one corner at a time and not be bothered with driving all over town.
