I just put new rotors on my car and new brake pads. When it was driven afterwards they seemed like they were smoking and grinding a bit. Is this to be expected?

Nevermind the grinding part, it's not that noticable. I had to change them because my squeeler never alerted me to their wear, therefore ruining my rotor in the process. Anyways, does anyone also have any advice on HOW to wear them properly? No hard breaking... etc? I can down shift but with my 4 banger its a little jumpy for me to do that. Any suggestions?

This sound like to me you have a caliper hanging up and not releasing when you stop braking. I would take it to the shop you had the brake and rotor done and they can test the calipers. You need to do is ASAP because it can cause damage to the part you just put on. If the place that did the work on your brake say nothing is wrong I would take it to a second brake/auto shop.

Does your brake pedal throb or pulse when you are applying the brakes? How many miles has it been since you changed your brakes pads? Do you have disc brakes on all four corners? With what you said in your question, it sounds like your rotors are warped. If so, then you will need to replace your pads and rotors. You should probably have your brake fluid changed too. This should be done every couple of years. Brake fluid absorbs water and water will boil if it gets too hot causing air to develop in your lines. This is why brake fluid is used rather than water. DOT 3 brake fluid has a high boil temperature. DOT 4 is what they use in racing cars. If your pedal feels soft or spongy, this could mean that you have air or water in your brake lines, which is not good and I would be hesitant in driving it.

There is something called "run in" when it comes to brakes and rotors.
Basicaly new brake pads don't meet flush on the rotors when first installed and they temd to make a little noise at first. Maybe the first ten times braking. But it should be more of a whooshing sound.
As far as the smoke, it's pretty much normal to have some light smoke coming from the brakes for the first couple times comming to a stop.
That being said, if something seems out of the ordinary, it's better to have it double checked just to make sure.
If you can put it in gear with your foot off the brake, it should roll forward. If it does, you should be fine.

Assuming the new rotors & brake pads were the correct application for your vehicle, and installed properly, it's not unusual for new brake pads to make some additional noise as they seat themselves to the new rotors. This condition should dissipate within a day or two. Most new brake rotors have a protective coating on them to prevent corrosion. New rotors should be thoroughly cleaned with a brake cleaner solvent to remove this coating before installing them. Also, care must be taken not to leave grease on the braking surface of the rotors. I suspect this may be the cause of the smoke you observed. This too should dissipate within a day or two. Keep in mind that extremely hard braking/panic stops or abuse can cause the brakes to become so hot that smoke may be emitted. Try to avoid hard braking if you can as the excessive heat can cause your new rotors to warp. Warped front rotors will cause the steering wheel to shake when brakes are applied. Warped rear brake rotors or out of round rear brake drums will cause a shuddering vibration that may be felt in the brake pedal or throughout the whole vehicle in severe cases.
Hope this helps you out!

they will smell,until the pads get set to the rotors,but for the grinding,it shouldnt do that,sounds more like a bearing.better check the calipers,to see if they are releasing the pads from the rotors,they could be sticking,and maybe that was the reason in the first place, why you had to get new pads and rotors.

Well, Most new Rotors have a films on them from keeping them from rusting. this can be washed off by soapy water. Now, The grinding part? Sounds like your brakes may not be properly installed.

If you did it yourself and arent confident, have a friend double check your work. If you had a mechanic do it, ask them about it. Pads and rotors do behave differently when breaking in, but did you actually see smoke? You saying it "seemed" like they were smoking is confusing.

It sounds like they didn't get everything aliened properly. Take the car back to the shop and have them to take care of it. It should not be smoking or grinding under any circumstances.

no it is not normal. who ever did the brakes forgot or didn't grease the slide pin on the calipers. every-time u step on the brake pedal it causes the caliper to slide up and down. those need to be greased

this is normal, but make sure you don't ride the brakes. brakes need to be burnished in,so that the brake pads seat in correctly
