Since your front rotors are RMs, I think it's safe to assume they are cross drilled and slotted? I am curious if anyone has ever machined/resurfaced them, or do they just need to be replaced? As far as replacing the stock rotors, if they are not entirely worn out, just resurface them. Around $20/pair or per disk, not sure. But definitely cheaper then buying new rotors at $200+ for a pair.

 

They are slotted but not crossed drilled. I am not sure if they would need to be replaced or not... What if they tell me the rotors are too thin, is there anyway to check to see if they are being honest? Measuring myself would be hard to do accurately. If so I will have to buy new ones.

 

Usually you could tell just by looking at them. Rear rotors even new will be thinner then the front ones, and more than likely not vented, since they only handle 20-30% of breaking. The best thing to do is to go to any auto parts store and look at generic rotors. They are all approximately the same thickness, especially if they are made for your car. This way, after 5 mins at the store you'll know whether or not the guys at the shop are telling you the truth.

 

i think it just needs oil then. because i can break from 100 without my hand on the wheel and it won't vibrate and it will break in a straight line.

 

John, do you have stock brakes front and back or aftermarket?

 

stock as can be. lol. well my pads aren't from the dealer. they are from kregans.

 

Straying off subject, but here is the recommended minimum thickness for rotors:

Front 30.0 mm (1.181 in)

Rear 15.0 mm (0.591 in)

 

haven't measured. but oh yeah forgot to answer a question asked earlier. my pads are pretty new. about 5,000 miles on them still very thick

 

Yeah, brake pads can be as thin as 1mm (absoluste minimum). I am not sure at what point they start to squeal.

Anywayz...
