So I have a question for everyone. I'm having the dealership put on some new pads I just got, (Hawk HPS) for front and rear and the dealership is telling me they cut the rotors so the pad fits correctly when they put them on. Is this correct or should I just man up and do them my self without worrying about cutting the rotors and what the dealership has shoved up it's butt?

Thanks

Chris

 

I think it's more due to the fact that when you bed in the pad you actually bed in the pad to the rotor so it's good to have some fresh rotors to do that with.

 

no, it's bad to have new pads and rotors at the same time.

 

How is it bad to have new pads and new rotors at the same time??? Doesn't every new car have new rotors and new pads at the same time?

Or do you mean, new pads without having rotors cut or new rotors?

 

The pads will bed more effectively if you use rotors that are already broken in. Note: if the rotors are FUBAR and your pads are toast, then you can't do much about it, and you have to replace both at the same time.

 

Well this is what I got from a few other people, that's it's best to have the rotors machined when having the pads put on. My rotors now aren't FUBARED, and the dealership even said it's better to have the rotors cut, because if you don't you get a lot of squeaking and what not and can do more damage then.

I just don't want yanked by a dealership. I trust them on certain issues, but brakes always seem to be more expensive once you get to the dealership.

Thanks for the help and I appreciate the input.

As long as the rotors are in good shape, I'd leave them. Their advice not withstanding, it wouldn't make a whole lot of difference anyway. If you get squealing it's more likely that they didn't feel like taking the time to do everything exactly how it's supposed to be done.


edit: it's also worth noting that some pads are just noisy, so check with other people who have used the same pads you're using to find out if it's just the compound.

 

You need to take the old bed martial off the rotors. otherwise you will never get the stopping power of the hawk pads.

You also will contamate (spell) the new pads. Yeah they like to cut them. Ask them to 3m scotch bright them to get the old pad off them. Then after 30 miles ...... dont hit the brakes hard til them. use them and let them cool off. then use them again.

You will have great brakes....

But you need to clean the old brake pads off..... Thats like forgeting to swap the gear oil after installing a used tranny.....

 

no, you don't need to get the old material off the rotors, unless it's unevenly transferred.

 

Well so far, the brakes have been great. I haven't really hit them hard yet and I've probably put more than 30 miles on them, so I should be good. They'll get their first real test Wednesday at the drag track.

i resurfaced my rotors then threw on the same pads and everything worked fine.there shouldnt be any problem

 

You want a nice fresh surface for the new pads to wear in with.. A quick ".004 cut on the rotors will give you a square cut surface which will break in the pads better and it will in theory provide better performance though you may not be able to tell the difference off the race track.
