Car in for service, need some quick advice on brakes
my rear brake pads are worn out and need to be replaced. Fronts are ok for now.
Do the rotors need to me machined with the new pads? Will I get any kind of odd braking or vibration if I don't get them machined?
Should I look at replacing the rotors as well when I replace the pads?
New pads will run me 178CAD or about 113US
new rotors about 120CAD each or about 76US
Any advice would be appreciated.

can you turn the rotors?
I have been told to at least turn the rotors for new pads. But when I put my new pads on, I did not get them turned, and had no major problems.
The issue will be that the rotors are already worn by the previous set of pads, and the new pads may not make as much contact to the rotor as the previous set, so starting with fresh rotors/pads would be best, but turning the rotors will be fine as well.

yes, the rears can be machined. I think that would be fine for them at this stage
Kind of concerned that the rears have worn down before the fronts though. Most of the stopping power should be from the fronts, right?

The rotors are designed to be replaced with the pads.
At the very least, you should resurface the rotors so the new pads mate properly with a flat rotor surface, but you may wear below the minimum thickness of the rotors, before the 2nd set of pads wears out...which is why Audi replaces the rotors and pads together, rather than resurfacing the rotors.

??? What does that mean?
The fronts do most of the braking, but if the pad thickness in back is smaller than the pad thickness up front, or the surface area in back is substantially smaller than up front, or the pad material in back is softer than the pad material in front...etc., the rears can wear faster.
I don't understand what you're trying to say when you say "the fronts just slow down, the rears actually do the braking".
