resufacing break pads?

I recently replaced my stock pads with Hawk performance pads and I didnt break them in properly so now they squeal like the stock ones did. The procedure I used was:

1 Accelerate car to approx. 35 mph.
2 Apply brakes using light to moderate effort to reduce speed to approx. 5 mph
3 Repeat 1 & 2 at least 10 times allowing 1/3 mile between cycles.
Allow pads to cool.

Anyhow is there an easy way to resurface them and start over or would I need to get new ones again? I think its kind of a dumb question because I dont think you can but I want to be sure.

It's probably not the break in that is the problem . Lots of pads squeal in this car - there are a few DIYs - see DIY section .

I was looking to get some brake pads resurfaced (due to my wheels binding on the caliper), and I had zero luck. Resurfacing brake drum pads are easy, but (as I found out) resurfacing brake rotor pads is evidently very difficult to do correctly, and I couldn't find anybody who would touch the pads. Maybe you will have better luck, but you are most likely going to have to come up with a different solution. If your brave you can always try to re-surface them yourself (with a nice belt sander, thats what was suggested to me), but I would tend to agree that resurfacing wont solve your problem. Good luck.

I second this, when I installed my hawk ceramic pads a little over a month ago I accelerated to 60 mph, then SLAMMED on the brakes till about 5 mph's (never a full stop) then repeated about 4-5 times. They've been silent as a virgin since.

Here is the official bed in procedure for Hawk pads from Tire Rack.

HAWK

After installing new pads make 6 to 10 stops from approximately 35 mph with moderate pressure. Make an additional two to three hard stops from approximately 40 to 45 mph. Do not allow the vehicle to come to a complete stop.When completed with this process, park the vehicle and allow the brakes to cool completely before driving on them again. Do not engage the parking brake until after this cooling process is compete.

NOTE: Hawk racing pads (Blue, Black, HT-10, HT-12) may require a different bed-in procedure. Contact your sales specialists at The Tire Rack for racing application information.


Your procedure was pretty similar to this, so it might possibly be your rotors, or it could be that your procedure was wrong. Were your rotors warped/cracked at all? You can try this procedure and see if it works, but I don't really know what else you can do.

Not to be Capt Obvious but did you use anti-squeal grease? My Hawk HP+ were fine with the correct break in three months ago. Now.... I hate them! They squeal sooooo much. Oh well, performance pads. You should hear by buddies 911 Pagids! WOW!!!

you didn't state which Hawk pads

but breaking them has little to do with squealing

I dunno about Hawk pads but the break in you mentioned is pretty typical for regular brakes. I second what has been said already: Its not the break-in that's making them squeal.

As for resurfacing, thats something that isn't commonly done anymore to brake pads due to the potential of asbestos getting in the air. Drum shoes you would find since shoes are reused, whereas pads are throwaway. I doubt you'll really find anyone who can do it...
