SO, i need a BRAKE JOB....I went to the mechanic to check and my rear pads are done.....But he tells me i need rotors...My next door neighbour works for nissan and also said i need pads, but rotors seem fine...How do i know if i need them or not.....The rotors look like the fronts and seem fine. But, how can i be sure...No need scratches on the surface..

 

First: If you got two guys telling you that rotors are needed and you have no clue what they're talking about, you may need rotors, specially if one of those guys is your neighbor and works for Nissan.

Second: You could take take a micrometer and measure the thickness of the rotor to make sure they're with in spec. Check your owners manual.

 

no, nisssan my neighbour who works for nissan is saying its fine...No need to replace...The other mechanic shop is telling me i need some

 

Get a 3rd opinion if you're unsure about the rotors. The mechanic who said you need new rotors may be saying that because it could have maybe a 6 months to a year left on them so better to replace them now than later could be the scenario.

 

IMO brake guys are rotor replacement happy. As long as they stop and there a decent surface to the rotors it is a little ridiculous to replace rotors most of the time.

 

depends.

Rule of thumb is replace rotors with pads, otherwise pads don't bed properly and then you have pre-mature wear.

 

if you need rotors i can sell you my stock rotors, they are in great condition.

 

Brembo rotors..

 

whats funny is that the rear right side is making a squeek....He tells me the rear right side rotor is gone. But then i ask him to check the other rotors and they are all fine....Bit the rear right looks like the rest of them...No cracks, no rust, no warpage, no nothing....I donno..Im gonna tell him to throw the pads on, if not, ill just go pick up my pads and go to another mechanic.

 

70 to throw some pads on.....is that a decent price...but the nissan wants 100...mite as well go to nissan

 

Pads bed due to friction with the surface and will do so properly even with the shittiest rotors in the world. You may get a terrible pulsation in your brake pedal but they will still bed. It's simply a function of friction.

You can change pads on many cars without ever changing rotors. Porsche recommends that you never change the rotors unless they are lower than minimum. To make that easy the designed the calipers with a pin & slip system that allows you to change the brake pads without even removing the rotors. I always would bed in two sets of pads, one for racing the other for street. Then when I hit the track, I could just slip in my racing pads and race right away and swap back to my street pads to drive home. (no squeeky squeeky...)

So if the rotors are within tolerable spec (on the rears there is very little use really so I would say they most likely are) then put some pads on and away you go.

 

Thats a good idea actually, I've always been under the assumption that rotors should atleast be turned when using new pads.

 

Oh my bad OP I misread your post. Ya these guys have the good dirt on your problem. Sorry man.

 

well, i just bought the pads and put em on, and everyting worrks perfect

 

You mean you didn't run head-long into a wall and explode in a fiery inferno of death?
