Did I Install Correctly? - Rotors

I just got done installing the front two rotors that I received from rotorpros. It was actually quite easy. I used the DIY from the org and it helped a lot and took my 1 hour for the first wheel and 30 mins for the 2nd wheel.

Prior to me taking off the calipers, front wheels were spinning freely without any grinding noise or minimal grinding when I raised my car. When I got done installing my new rotors, the brakes were biting on the rotors and was making a grinding noise when i spun them. Is this normal? Should I be concerned? I don't believe you can screw up on this since the procedure simply involves removing 4 bolts and putting it back in the same place.

Another thing I noticed after the install was that I hear like a deeper screeching noise when I go really slow and when the car is just about to come to a stop. The noise is there when I am just about to stop from going maybe less than 5mph. Is this due to the rotoros being new?
 
I used my old pads. They looked brand new.

What do you mean by compress them? I didn't have a problem putting the calipers back on. I'm just concerned with the grind...

Crap... I googled and I think I know what you are talking about... I gotta set the pistons back to it's original setting when it had new pads. I absolutely didn't do this.

If I reused pads, should I still compress them?
 
As your pads and rotors wear the caliper piston extends out of the caliper more, when replacing the pads or rotors you need to compress the caliper piston to allow clearance.

After you re-install everything you then pump the brakes a few times to re-set everything.
 
Crap..... Thanks for the advice. Back to the garage again... I don't have a C clamp handy with me... any ghetto way of compressing the rotors?

I compressed them all the way down and started the car. I freaked out when I first pumped the brakes because there was absolutely no pressure. I pumped it couple more times and the pressure feel came back. I took it for a spin and used the brakes under normal driving conditions. Prior to compressing the pistons, my wheels were literally covered in brake dust for such a short drive. Now that I've corrected it, it looks like the brake dust appears to be normal.

I'm so glad I got help! I think I would've eaten my almost brand new pads and ate through my rotors too. I think it's fixed now and it's all thanks for the helpful advice! :tup: I really appreciate the help. I just hope I didn't screw up my new rotors. Do you think I might have messed up my front rotors from my 2 to 3 mile drive testing them prior to compressing the pistons?

I am going to install the rear tomorrow night. I learned quite a bit from this install. I don't think I will screw the rears.
 
Just got done installing the rears. I changed both rotors and pads at the rear. It took me about 15 minutes trying to remove the lower bolt that hold the brake clip thingy. That thing was on sooo tight and there wasn't enough space to get my torque wrench in there. I must hammered it for good 10 minutes after I greased it up.

I test drove it for good 5 mins stopping frequently and looks like everything is working as usual. The rears have minimal brake dust.

I love the help i get from :iS: :tup::tup::tup::tup::tup:

any squeaks?

No squeaks at all. I made sure to use that brake lube thingy that you apply behind the pads. Brake change is probably one of the easier things you can do. I think the dealers charge so damn much because there is so much manual labor involved. I changed my mazda pads after the infiniti and it is MUCH harder to compress the brake pistons back to the original place. It was ridiculous. I had to go rent a tool from autozone to compress the pistons. The next time I do this, I will just go rent the tool first before I take the calipers apart.

Anyhow, I think everyone should try to do their own brakes. It's actually quite easy. Even a noobie like me did it in the end. I did have some problems, but it was because it was my first time.
