Machining rotors

[Brody]

QQ,

What sorta prices have you seen to machine rotors?

Ive just gotten 2 quotes, 1 for 60 per rotor, and another for 27.

Seemed abit steep just to spend 5 minutes shaving some metal...?

I will have the rotors off the car.

27 sounds more like it! I have to get mine done all the time, I think I pay 50 for the pair.

Instead of maching your discs just buy some slotted ones i paid $400 for mine and fitted them myself. It saves the hassle of maching your discs everytime your brakes start to squeal or watever.

$50 is much cheaper than $440min (if i was going to buy new rotors i would get the dba 4000).

1 side question, DBAs website says original thickness - 30mm, min thickness, 28mm. So with abit of wear, and then having them machined, theres not going to be a great deal left?!?!

$30 a pair and 1.5hrs up here Brody.

I could be wrong but I think the amount worn and the amount machined is tiny compared to 2mm (ie. machining takes the thickness down 0.05mm?)

Please correct me if I'm wrong...

I'm starting to get some rather extreme brake shuddering under what I'd class as medium braking. My pads still seem pretty chunky, but the front rotors arean't to smooth to touch.

Is it worth getting all 4 rotors done?

Machining is definatley worth it.:uh-huh:

Shuddering usually means warped discs. If your discs look worn then get them done.

It's like a tetanus shot: If you can't remember the last time you had it done then it's due (same for bleeding the brakes ).

strutto - the amount removed from the disc is dependant on how deep the grooves are. The machining takes them back to a flat surface.

I paid about $50 a disc, done thru reputable race workshop who's done lots of suspension work for race car (including Brock's Monaro). Definitely remove my shuddering problem. I think sometimes you get what you paid for. My disc was machined last year (probably cost less than $50 a disc) by some common brake shop and even after machining it, brake shudder remains. So we ruled out it wasn't the disc and waste time for a year checking wheel alignment, balancing rims, etc. Turn out it is due to to poor machining job on the disc last yr. With this recent $50 a disc job, it fixes the problem. I shouldn't have wasted so much money on alignment and balancing....
