Default Rusty Rotors - how rusty is too rusty?

Hi guys,
this isn't about either of my Hondas but rather for a 2001 Volvo XC70, but it's a general question and I don't belong to other forums so i thought ye wouldn't mind if i asked here where i trust the advice i get :-)

my brother is visiting from up north and he brought me a whole mess of car problems that he has neglected to get done. We replaced his control arms, fly rods, sway bars and did the basic 110k tune up. doing all this i noticed his brakes were so worn and rusted that they were falling apart so we did that too. the front rotors themselves looked fine but given the state of his pads i thought it wise to check his rears - and since we were doing his fuel filter anyway i figured it couldn't hurt. well - see for yourself.

i hate to pile the repair bills on him but wouldn't i be remiss in not at the very least having this rotor resurfaced? that isn't typical yankee salty-roads rotors is it?

please let me know
thanks!

No problem! A car is a car, and brakes on most cars are similar!

Looking at that rear rotor, I can tell that about half of the stopping surface is reroded and literally rotted away - you can see this by the size of the orange rusty area. The only contact area is the inner black circle. I had a similar problem on my Accord and the rotors were so pitted and rusted that there was no point in resurfacing them - just got new ones. I recommend you do the same. If you can do the labor yourselves, you should be able to save some money. Your rotors look pretty pitted too, and I would get new ones. Look up on google also what a good and bad rotor looks like, this should be some good additional info for you as well.

I used to have an 06 volvo s40 and as soon as my breaks got wet (after washing the car or rain) the next morning i would have rust. but with my normal driving the rust wore off but the edge always had a little bit. but my pad took off at least 95% of the rust when driving. never had that much rust after driving like in your pic

Talking I Agree :)

Replace rotors and the hardware if it looks that bad..check brake lines and brake hoses and also replace..if you do the job you do it right..or suffer the problems later...
