Hi Guys,

Today I went for the usual yearly inspection and I was told it would cost around 850$ to replace both front and rear rotor/pads.

My Subaru Impreza rotors are 275mm. Has anyone managed to make a rig to clean the rotors.
 
If the rotors are at the wear limit then there's noting that can be done.
I recall reading that OEM rotors tend to be thinner today so don't have enough thickness to resurface.
 
I have only ever replaced rotors on my 98 K1500 4x4 because they warped beyond repair on a regular basis. Too small for the weight of the truck and payload.

I'll just share my history with rotors. It used to be common practice to have the rotors cleaned up / trued at automotive machine shops. Even some mechanic shops had brake lathes that would do drums or disc machining. They saved a lot of money back then and made sense. The rotors had a minimum thickness that was easy to find.
But, the last time I took some rotors in that were plenty thick, I was very disappointed in the work that was done. The rotors clearly weren't set up correctly. They don't have machinists running those brake lathes. When I put them on and checked with a dial indicator the faces ran out more that ten thousandths. So I had to buy new rotors and they ran quite true.

My advice is to shop around for a better price on your rotors. Sounds to me like you are taking to a dealer with those prices.

I got a pair of new one too. Subaru wanted 850 just parts rotor brake pads if you did not order them online that have big discounts. I don’t use them very often as I do 80% highway. So if the minimum is met after the cleanup I would very moch like to save 300$

Meaning how did I replace them? I just bought new ones. They were cheap though, like $80 a piece so it was not a big deal.
I used to have a 2000 Subaru Legacy that was a brute to have repaired. Loved the car because of the snow handling but it was a total lemon and it bled me dry so I sold it.
