Can't overemphasize how important proper bed-in is, it basically removes the top surface of the pad onto the rotor so there is a common material on the two braking surfaces. It's a very aggressive procedure as far as the heat generated and the proper time it takes to complete the process. Each pad has different bed-in procedures but most are basically similar. If bed-in is done improperly it can leave too much of the pad in one spot on the rotor or not enough of the pad material distributed throughout the rotor leaving uneven spots. Sounds like that may have been the case and like Ryne mentioned a better quality pad would be a good idea next time around.

 

Another reason I recommend Akebono ProACT is because their bed in procedure is... well... just drive is as you would, lol. Fool Proof!

 

Over-torquing the wheels on installation can also lead to warped rotors. Some shops will just run up the nuts with an air gun and not properly torque the nuts. I think the previous suggestions are more on point but this is another thing to consider.

 

That's what I figured you'd say, lol. But do you know that for a fact? Or are you just saying that because it's Autozone's house brand? But yes, if I get them turned, I'll put new pads on. How much should it cost to turn the two rotors? Also any other good pad recommendation guys? And bed in process?

 

Stoptech pads for me. Look up track bandits bedding procedure. Most bedding procedures are going to be various flavors of hard braking with cool downs between. I like 6-7 reps of 75->40, with a couple minute cool down between.

 

The main thing is DON'T be braking w/ the vehicle completely stopped during the bed-in, the pads will literally bake onto the rotor and leave high spots.
I also have Stoptech Street Pads, great pads although a bit dusty (small price to pay for the bite).

 

Yes, sorry. Don't stop, the temperature will deposit more brake pad material in one spot and you'll get high points again.

When you brake with properly bedded brakes and rotors, the layer of brake pad material on your rotors is continuously broken down and rebuilt. Bedding your brakes deposits more than it breaks down, basically.

With this in mind, rush hour is not a good time to do this, nor is an especially crowded part of town. I usually choose really early in the morning in a deserted part of a highway, so I don't alarm people.

 

Might even call the police dept. and explain what you're wanting to do, they may have an area they'd recommend.

 

I'm not saying your pads are the problem, but they are suspect just like every part of the braking system. I am biased because I have these pads on my car and they are the most well balanced pad I have ever had. They have great stopping power with out any drawbacks like noise. Also, they do not have a bed in process. Akebono says to bed them in by driving the car normal. This leaves much less room for error.

 

Could that just be with the stock rotors? Cause I have slotted? Can one pad need a bed in process and the other not? Anybody else have any recommendations or experience which pads would be best with the rotors I have?
