My friend goes to school at UTI and he is going to align and change my break pads for free but he told me he already passed the class where they let you resurface the rotors..i was wondering if its necessary to resurface,if it is I guess I can take them off the next day and take them to a shop to get that done
Btw I have brembos..

 

Its not required but new brake pads need a fresh surface to bed into for max performance and no noise.

 

Not required but if you don't your pads will wear out unevenly

 

That's a pretty general statement to address an issue that really needs to be addressed on a case-by-case basis.

It depends on the condition of your existing rotors at the time of the pad replacement. Some rotors (based on their condition) should be turned on a brake lathe to even up the braking surfaces, some rotors are not technically capable of being turned since their factory runout measurements will put them out of spec if you use a brake lathe on them(as is the case with the factory-equipped Brembo rotors on some G35's), and sometimes the rotor wear is very even and uniform and it's just not necessary to lathe or replace them.... and you just slap some new pads on and go. I usually end up not having to resurface my rotors, but there have been times where the rotors on some of my older cars that I've owned were in sorry shape and I just replaced them. A lot of it depends on your driving/braking habits and the environment in which you drive.

 

Depends, if the rotors are running true and within specs you can get by with scuffing them with fine sandpaper to remove residue. Then do the "bed in" process after your pads are installed. (search)

Its a general answer because its a general question. Also it costs around $20 generally to resurface rotors, so it would be foolish not to take the extra precaution especially when it cones to brakes and given the cheap cost.

If there blanks generally you can resurface the rotors at least once if there under 30k. You can't resurface slotted and drilled rotors.

 

How do you know when u need new rotors?

 

there's a set thickness that the rotor needs to meet in order to be able resurface. Once the rotor becomes too thin you cannot resurface.

 

It's not required but much better to. Also scrub and clean the crud off the brackets before lubing everything up as well.

 

The rotors have the minimum thickness stamped on the edge. Measure it with a caliper.

Also no, you don't have to turn your rotors when changing pads. Especially if you are keeping pad material the same, ie oem to oem.

 

I've just slapped new pads on several different vehicles and never had a problem. That's assuming they don't have significant runout problems or deep groves or anything. I think you'll be fine if they're in decent shape.

 

Not necessary but depending on the condition of your rotors it would be recommended.

 

Is there a certain type of grease/fluid I am supposed to apply to the stoptech street break pads I ordered for my brembo calipers? I am finally changing them tomorrow,my current ones are DONE.

 

You don't need any fluid or anything, but clean the rotors off with some steel wool and brake cleaner to remove the factory protective coating

 

ideally...........yes! If not , then buy new ones..........IMHO!
