Brake pulsating.
 

My Alero has some serious pulsating issues and this is the second brake job that his is happening on. Is there more heavy duty brakes that I can install to prevent this. I have drums in the rear too, is there any way to change those to discs?

Anything but the stock replacements are more heavy duty than the stock ones. The stock rotors warp fast.

Or you can upgrade to Corvette brakes, Brembo big brakes, etc. Check out Aleromod Upgrades too for your options on pads and rotors.

A set of decent rotors from napa would do the trick. The stock rotors warp easily like ion said, and so does just about any rotor from advance or autozone.

i got the same problem. my brakes are warped horribly. does this mean i need to replace pads as well? (sorry for thread jacking!)

Unless you want to gouge your new rotors just to save $19.99 on new pads.
