Squeal. AFTER EBC pads and new rotors (pics).
This weekend we installed new rotors, EBC greenstuff pads, and did a full brake flush with DOT4 fluid.
What sucks is that I NOW have a brake squeal from the rear passenger.
It only happens right on startup...when they pads are cold....after they're warm there's no squeal.
I used a BUNCH of sound deadening spray on the backs of the pads. You can actually see it in the pic.
Questions:
1. WHAT WOULD YOU DO? Take out the pads and spray even more deadening spray on the pads?
2. What about sand paper on the rotor?
2. I havent done anything for break-in. Just started driving. Any special techniques you use for break-in?

My newly installed EBC pads squeals too. Though, I didn't put any deadening spray. You could spray the rotor with water, that helps a bit.
The red layer of the pad in contact with the rotor is the break-in portion.

Sorry man. Didn't mean to imply that. I just noticed the red/orange goop along the edge of the pads contacting the disc in the second picture and put hand to head and hoped that wasn't the case. Very glad to hear that it's not!

Per EBC most asked questions:
Bedding in EBC pads
In Street use situations …
Bedding in when the red EBC surface coating (marked on the pads as Brake In) is applied.
Best procedure is to drive gently avoiding harsh braking unless in an emergency for first 100 miles. In the second 100 miles (up to 200) you can use gently increasing brake pressures when using the brakes.
Only after 200 miles urban driving (not 200 miles on a freeway where brakes are almost unused) should you attempt to apply heavy load and heat to the brakes. To do this final bedding on a QUIET ROAD in safe traffic apply the brakes and slow from 60 to 10 MPH five times in a row. Then drive slowly for a few minutes if safe to do so to allow the brakes to cool. Try to avoid coming to a rest whilst the brakes are heated.
A smell may be noticed from the warm brakes, this is normal. Repeat this procedure a second time after the brakes have TOTALLY cooled down. EBC pads get better with miles. Even after this bed in procedure it can take up to 1500 miles before the pads are at their best. In the meantime the pads will be good and safe but true potential not realised. EBC makes performance pads that last, they do not bed in within 5 minutes driving. Noises will be more likely during the first 1000-1500 miles use whilst this chemical bedding takes place.
