I had my rear brakes done at the dealer about 2 weeks ago. At the time, they said my front pads were still good (about 50%), but that the rotors were glazed and should be machined, so I went ahead and did that.

Now I'm thinking I'll just go ahead and do the front pads myself now. (Believe it or not, they are the original front pads after 65K miles.).

My question - can I just replace the pads or do I need to machine the rotors again? I've put about 500 miles on the car since the front rotors were machined. How many miles max can I get away with before needing to machine them again (in case I don't get around to replacing the pads right away)?

TIA

 

Machine them,

Oreilly's will machine rotors or you may find a mom and pop shop that will machine them for you pretty cheap.

 

Bump for the morning crowd.

 

You'll be fine. Don't waste your money.

 

When I did my rear brakes for the first time, I wasn't able to get the rotors machined. I put the new pads on over the old, grooved rotors (not ideal, I know). Never had any issues.

 

It's not just the matter of not wasting your money, you can only turn them down so much before they must be replaced.

 

you should be fine, if you managed to keep 50% of the pad life minimal if any damage should have occured to the rotor. You would be better off replacing the pads then doing the rotors. the only thing I find odd is that the back brakes had an issue before the fronts

 

Glazed Rotors dont require machining. Just a good scuffing
from some 100 grit sandpaper. They tore you a new one there.
The 'glazing' is actually brake pad material that has transfered
to the rotors. This is a good thing. Rotor machining is not
determined in miles but in the actuall condition of the rotors.
In a perfect world, rotors almost never need to be turned.
A simple deglazing will bring them to life again awaiting the
new brake pads. A cross hatch pattern is what you are looking
for. This allows the new pads to 'bed in' properly.
Google 'bedding brake pads'.
If they rotors are not smooth and properly glazed but scored and
have deep circular grooves in them, then its time ti machine them.
The deep grooves would be from not replacing the pads in time
and actually have the metal bacvker plate on the pads ride on
the rotors instead of blake lining material.
Inspect, determine, turn or scuff and install new rotors.
The rotors themselves have a minimum thickness cast into them
in the form of a number in thousands of an inch.
The very edge of some OEM rotors has a divit cut out of the edge.
Turn them past this divit and they could explode under heavy braking.

btw, Did they turn these rotors on the car or off the car.
In your presence or behind your back?
Rotor turning is the biggest scam in the book.

Its not that odd.
My rears are taking a beating and the fronts look like new
after 40K miles. But then I dont use my brakes unless I really need to.
New rotors are soooo cheap, why would you not want brand new rotors
instead of turned rotors and pulsating brakes.
