Arrow New Rotors with Old Pads

Rotors: New - Zimmerman coated

Pads: Used - Original Equipment, with 70% life remaining



I'm looking for some feedback in terms of proper break-in/bedding procedure for the combination listed above. The front pads had too much meat on them to throw them away, and spend $80 on replacements.

The plan is to take the OE pads and run them along a sheet of sandpaper, against a flat surface (concrete/metal block) to smooth out any previous imperfections.

I would just do a traditional brake bedding procedure (google). New pads would be optimal though.

Sounds like a good plan with the sandpaper, to remove the glaze and get down to some fresh friction material.

+1.
I have those rotors and they are really good and totally worth it.

I don't think sandpaper is necessary. Just bed them in.

Sandpaper might make it less smooth.
You're comparing sandpaper to a smooth metal rotor here.

??

The surface of new brake pads are not smooth, don't need to be. If the old pads are not glazed you could just put them on and bed them in. If they are, spray mount a sheet of medium grit onto a piece of glass and sand down to good material. Not complicated.

Update:

I replaced my rotors last night, didn't bother sanding the pads as they looked quite even and smooth.

Turns out the old pads were Raybestos, and not OE. I'm not sure how to feel about this.

If they work they work. I don't see the problem.

Re: New Rotors with Old Pads

I work in a shop, we installed couple Raybestes pads on Honda Odyssey, amost everybody came back with the squeaking complains. They are inexpensive and quality isn't good.
To make your setup perfect, I think you should get OEM pads since you have already spent on good rotors.

OE pads are great in many respects for normal street use, but they create HUGE amounts of brake dust. I was so happy to replace mine with fairly inexpensive semi-metallic pads. I bought the Axxis brand from Turner Motorsports and they don't squeal at all and generate maybe 1/3 of the dust of OE pads.

+1 for the squeal.

I've put brake disc lubricant on the back if the pads this time. So far this week, I am noise free.

New Rotors with Old Pads

I bought the Zimmerman coat z's and OE Jurid pads and bedded them properly on my 330ci. No squeak but there is plenty of dust. Can't beat the solid bite of OEM IMO.

What if I told you there's a once a month application you can put on your wheels to completely eliminate brake dust?

Armor all wheel protectant, usually lasts me 6 weeks

It works OK; not magical but a good product.
