New brakes and rotors why are they smoking?
 

New front pads and rotors installed less than a month ago, took the car back cause the brakes seemed spongy. Mechanic said he fixed the problem still, but they are still not correct.
Went out that night and went down the quarter mile (twice), braked hard and they started smoking bad! WTF is this normal? Braking time sucks now i have to brake twice as hard. The other car already turned around i was still braking - it feels as if it has no stopping power. What to do?

Which started smoking? Fronts? Rears? One side, or both sides?

What type of pads? After they cooled down, did you regain normal braking feel?

Change your fluid?

What brake pads did you get. I will soon have to replace and wanted to know.

sounds like crap pads to me

i got alot of smoke from one of my cars just a few days ago, but only in the first 2 stops during the bedding in process, i imagined that it was just the film crap on the rotors burning off. and yeah the braking sucked those first few stops but thats just how it works, now everythigns all bedded and they feel great. well as great as a saturn can and im using stock pads and cheap autozone rotors, but its on a saturn tho, i use much better brands on my maxs/shos.

check ur slider pins, my 4th gen froze up and the braking performance suffered greatly

I had frozen calipers and my front rotors were grooved not too long ago so i know the feeling. Just double check everything. Check you calipers to see if they are working, and then take a look at your rotors to make sure there is a layer of brake pad material on the entire surface of the rotor. Otherwise, take it to another shop and have them bleed your brakes again.

Need to know the answers to his questions for any help.

i had someone replace my pads when i first got my car and the mounted the pads wrong and when i replaced them they were worn crooked somewhat. and my brother had told me that they were smoking regularly when he saw me drive by. my guess is check the pads to make sure they are correctly mounted and not lopsided or leaning or anything. im not sure how this is possible but it happened to my car.

The only one that smokes under hard stops is the passenger front. After the hard braking the stopping power sux, it feels like there is none.The pedal still goes to the floor to stop.
The fluid is new, the brakes have been bled - i watched them do it. As far as what brand they are - idk, i guess generic rotors and pads. I have the invoice but it does not specify what brand they are.
When it is light outside i will examine the fronts and see if they are seated correctly, and everything is correct..........

Sounds like the piston is sticking in the caliper, it is possible that when they pushed the piston back in the caliper it went in crooked. I'd bring it back and have them check it.

Whenever you replace your front rotors they alway smoke mine did the same thing eveytime and my buddy chris has a 4th gen and his did the same it will go away once you break them in.

They shouldn't smoke. Did you clean off the oil with brake parts cleaner or soapy water before installing the new rotors?

Im not sure what my buddy chris used but i purchased cheap rotors so that could be the reason and ive seen a number of people who brakes smoke and most of the time they say its because there new.

When i install my rotors i make sure i dont get any grease or anything on them so i dont think it would be from that.

No, I mean you have to clean them off right out of the bag. They ship them out with a light coating of oil to keep it from rusting in transit/storage.

Did u check and see if around the pistons on the caliper are leaking ive sen that happen before and it does cause problem with braking.

I learn something new everyday ,nope i dont clean them but now i'll start.

They should never smoke even when you first install them new. If they are smoking, that means your brakes are definitely binding. Make sure to check your caliper pistons in case any of them are frozen, then check the brake pins to make sure that they move freely and aren't seized in the mounting bracket.

wen u get new rotors you need to spray them down with carb cleaner ad wipe them down really good cuz wen the factory makes these OEM or JDM rotors they coat them with oil to prevent from errosion and rust. if you did not wipe them down then the oil will burn due to the friction of the pads. that is the reason y there smoking.
