new brakes and rotors. bedding advice

was looking through old threads but didnt find what I wanted to know.

Have new EBC rotors going on front and rear, ones from blackops. Also have hawk hps going on fronts and stoptechs on rears. Reading EBCs bedding procedure and comparing it to the brake pad bedding procedure makes me confused. The rotors it seems need up to 1500 miles of light use before bedding ive read but the bedding procedure for pads seem like they call for bedding more immediately.

in my mind i gathered that once the zinc is completely gone off the rotors which would be pretty immediate, then the pads are completely mated to rotors and you can bed them without worry.

seems kind of old fashion becuz you can bed with someone these days without being their mate.

So which is correct?

Thanks!

Update on the EBCs.

Waited a few hundred miles to try and do the bedding procedure. Seemed like most of the zinc coating was gone. EBC says wait 1100 miles or something but I had new hawk pads too so I thought sooner would be better. No particular reason. Now I noticed sometime after bedding them, not sure how long after but under 1000 miles, noise coming from the front wheels in parking ramp while driving windows down. It gets louder when gaining speed and remains while braking. I'd say after 10 mph. Sounds metal and cyclical like something every rotation rubbing maybe.

Trouble shot the heck out of this but so far same noise. Havent tried new rotors cuz u cant just throw rotors on and take em back. 20k miles on 2014 srt. Doesn't seem to make the noise on lift wheels off in drive at speed.

I've seen posts of other vehicles with the zinc coated EBCs having same noise.

Long post but wondering if the zinc is on my pads and causing the issue. Dunno if it makes sense but I've seen people say that you should actually manually remove zinc and since I didn't use EBC pads maybe the Hawks don't have the coating to deal with it like the EBC pads do.

Srsly I'm lost and if it ain't coming from my front differential at this point it has to be the rotors.

Re: new brakes and rotors. bedding advice

When I installed my Brembo cross drilled rotors they made a crazy rubbing metal to pads sound until I got all the zinc off. I was concerned I did something wrong, but it's straightforward job. Once the zinc wore off and bedded the new pads it went away, now they're quiet as heck. Brembo instructions said to make several stops under 30mph until it was gone, if not the distribution would be uneven and build up on the pads. It took me driving around my neighborhood for 2hrs making stops no faster than 30mph until it all came off. I was stopping every few miles to check the progress and it felt like forever.
It's an easy check to pull out the pads to check just for reassurance. Did you bend the brake shield behind the rotor by accident?

Hey Mate

Im looking to upgrade my disc + pads soon after doing my service i was told its low.

Would you recommend the Brembo Cross drilled at all? Im thinking of getting the slotted but not sure which one will also look good on the car!

Re: new brakes and rotors. bedding advice

They're really just for cosmetic purposes and the stock rotors are great also. It all depends on what you want to see through the wheel. I really don't think they grab any more than the stockers to be honest. Stock pads and rotors are a great set-up IMO, in exception to the brake dust if you like your wheels clean.
My rotors serve their purpose of looking mean and not cheap.

agree w srt ninja, oem pads and rotors work just fine but being acd, the dust was a major pain. took advice from scott and got cross drilled, hawks pads front and stop tech back. in my uneducated opinion work just as fine as oem set up but without dust. no complaints and as srt ninja pionts out looks awesomely. good luck w your choice

Re: new brakes and rotors. bedding advice

@OP, why didn't you match rotors w/ pads btw? Check the pic attached, done my upgrade this summer and it's a whole new different ride now

And, sorry I couldn't agree abt "it's aesthetic only". OEM rotors/pads are the first thing to replace when you get new car according to each drivers road habits and preferences, or simply you don't have any performance upgrade at all.
