Should I change them now... the front left wheel is squeeking loudly and has a high pitched noise.. and today i drove to work and nuttin??? Im taking my car in tomorrow to the dealer to replace all break discs... its worth it yeh??? to change now?

 

Yeah get new pads and get the rotors turned while you are at it. Think about going with some hawk pads. They are nice and don't leave as much dust as OEM pads.

 

how many miles you got in the Z? i changed mine at 16k and the front pads were probably at 25% and squeaked a little.

 

There is little advantage in replacing brake pads early: it just makes your wallet lighter.

When the pads need to be replaced, you will hear it - an unmistakable grinding sound.

 

o believe me it grinded hard last night... and today was a little better

 

Then replace the pads on that axle. As ZCARBANDIT mentioned, turn the rotors.

 

What do u mean by that.. rotors???? axle?? lol

i think i have to buy them as a set of 4.... im taking it to the nissan dealership... or do u think it would be cheaper to buy my own disc brakes and get them done somewhere else?

 

,...

 

Casanova, you shouldn't have to buy your rotors or pads as a set of 4 as they will wear differently front to back. I did front pads & rotors at 25kms, and back at 43kms, but that's just my Z & my driving. Make sure your rotors are machined/skimmed as well, if the rotors are still in good condition.

Seriously if your brakes have seen better days get it sorted asap!! Please.

 

Yep went to another place.... charging me half price... unbelievable.... nissan dealerships are rip offs man.

 

One thing to remember is not voiding your warranty if that is a concern for you as your Z is an 05. Consult your owners handbook.

 

Geez, you guys really have cash to waste ?!?

Do NOT turn your rotors when you change your pads unless they need it (Bad run out, warped - this is rare). Put new pads when the brake warning spring squeal (this is not temperature sensitive) and just bed them in.

Turning rotors... pfawh !

 

I ALWAYS turn my rotors when I change pads.

Why would you put a smooth pad on an unsmooth surface. Thats just less surface area touching... Plus old pad material is bedding into the rotor....

 

Because the new pad will wear within a few days and it's "smooth" surface will change to conform to the ridges on the rotors. If it's surface area you want, you'll get more this way. It's not very smooth to start with in any cases.

Old pad material will rub off pretty fast.

Turning rotors = removing material. On a rotors that only allows for 2mm of wear before needing to be replaced, it's a waste of money. I admit that if my business was selling rotors and charging for turning them, I'd recommand turning them each time too...

We just need to be careful with the new pads and remember the brakes won't be at 100% right away.
