This stems from an argument I had earlier today, and I do not know enough to speak intelligently on the subject.

When replacing the front brake pads on a 2005 Sienna, should
a) the rotors be machined?
b) ceramic brakes be used?

I have been told that machining rotors has gone by the way-side since 1992. I was also told that ceramic brake pads will warp and tear rotors.

Any information you have would be greatly appreciated, reference material absolutely awesome!

Here is some reading hope this helps.

You did not specify how many miles you have with your van. Is it the second time you change the brake pads? Machine or not depends on the thickness of the rotors. I would suggest you change both rotor and pads the same time if money is not a concern. Ceramic pads are OEM pads, stick with ceramic.

Vehicle has 123k miles, and this is the first time I have changed the pads, but the car was bought used at 99k. Money was a concern, but not necessarily directed toward what I am looking for. Essentially, is the practice of turning the rotors still recommended by ASE and/or Toyota? I cannot seem to find that information on my own.

At this mileage and you bought used. I would suggest you to change the pads and rotor together. For myself, I change the rotors with the second pad replacement.

Some people/shops will machine rotors. Others tell you not to bother since you are reducing the thickness of the rotor. Rotors aren't that expensive and you cannot put a price on your safety. It's not like this is a Ferrari.

Look around and I'm sure you can get a good deal on rotors. I would get a better set of brake pads and make sure you lubricate your sliding pins and calipers good.

According the service manual, the front brake discs have to be at least 26 mm (1.024 in.) thick. I think it is no need to replace discs if they are not worn out or damaged.

19. INSPECT DISC THICKNESS
(a) Using a micrometer, measure the disc thickness.
Standard thickness: 28.0 mm (1.102 in.)
Minimum thickness: 26.0 mm (1.024 in.)

Just did front brakes on our van, checked rotors and they specked out OK. Our van has 98k miles on it, on the back of the pads it was stamped Toyota. First time changed? I bought Akebono ACT906A and they were the best fitting brakes I have ever installed in 42 years of working on vehicles. I have not heard of this brand if it wasn't for Sienna Chat. I always bought from auto parts stores and are very impressed with them.
