New brakes and rotors make rubbing sound

I just installed new front brakes and rotors on my '14 Tacoma. I used the basic brake and rotors available. Nothing fancy or expensive.

Everything was working perfectly, but after about 15 miles with the new brakes and rotors, when I come to a stop, I can hear and feel a rubbing sound coming from the brakes. It does that when the truck is about to stop. I've searched forums and cannot find anyone with this issue. When people have issues with brakes, they describe a squealing or grinding sound. But mine is different. Mine may be more like a grinding sound, but it's not high pitched. It's a rubbing sound and it causes a minor vibration that I can feel when I'm in the driver's seat.

I know the brakes are new but can't think of why they make a rubbing sound that I feel. I just need some direction as to what to do.

 

Any chance you are hearing the front differential cage bearing? It's most noticable as you come to a stop.

 

Also did you seat the new brakes?

I’d pop my head back under there and check everything visually, make sure nothing obvious sticks out.

 

Backing plate or wheel bearing

 

I’ll have to take that in to get the front differential cage bearing checked but I don’t know if that would be it.

A few weeks ago, I replaced pads only and that rubbing sound was intense. Three days ago, I replaced rotors but kept the same newer brakes that I just put in. That rubbing sound was gone and stopping was smooth and quiet. But after about 15 stops, the rubbing sound came back.

And this new post came in mentioned something about seating the brakes. I have never heard of that before. Please explain that to me because I don’t think I did that.

 

Bedding the brakes is not as common these days. Pad composition really makes it unnessasary.

 

The brakes I purchased came with shims already attached to them. I did not use the shims that came standard with the truck. Also, I put brake lube on the back of the brakes before I inserted them into the caliper. Could that also be the issue?

I also used the cheapest brakes and rotors that Auto Zone sells in stock. I wonder if I should've gone up a level with the brakes.

Also, I was reading about brake and rotor bed-in and it mentioned something about brake judder. The term "brake judder" would be the best description of my issue.

 

I know this is an old thread but were you able to ever figure out the problem to your rubbing noise? I just replaced my rotors and brake pads and now when braking at low speeds I hear a rubbing noise from the front driver side brakes.

 

The last time I used the cheapest pads I could buy I was replacing the pads in about six months. Never did that again.

 

When you do the brakes, it is important to remove the slide pin (for lack of a better term) that the disk housing rides on and clean it up and lubricate it. Also, clean the pistons because they will be set in deeper with the new pads and dirt and rust is a piston seal killer.

Not doing that once cost me a new set of rotors when the brakes rode them and they warped. That mistake will never be made again.
