Top half of Front brake rotors on 2016 Tacoma rough or pitted.

The bottom half of the rotors are smooth. I had just over 6k miles when I notice this. Any ideas as to what is causing this? Would this be from bad pads, rotors, or calipers. Would this be something covered under warranty? TIA

 

need pics

 

Rotate the wheel 180° (clockwise or anti-clockwise, doesn't matter) then the "top half" will be smooth.

In all seriousness, please explain what "top half" and "bottom half" of a disc rotor mean to you--and remember every picture is worth 1000 words...

 

You beat me to this joke...all I could think of when I saw “top half”

 

if you mean like this, this rotor is what they -all- look like after
a few thousand miles

 

As I look at the photo, it appears that the smooth area is between a band of rough surface near the hub and the outer portion of the rotor surface (what I called the top half). The rust pocked area is the smooth portion (rained last night). So, do I have a bad brake pad or bad rotor? Both passenger and drive sides are like this. TIA

 

something is fucky with your brakes. looks like something NOT normal going on.

that should be a much larger shiny surface and no rumbly looking gray area above

it should look like the pic I posted. yours looks like incorrect pads
or something else problematic.

(the surface rust you show is normal when it rains)


yes warranty would cover that, as that is not normal. PLEASE pull a wheel off and
take pics of what is in your caliper and how pads are installed (if you have the time)

 

Something is significantly wrong with that brake, most likely at least the outer pad--though it almost looks as though there is no outer pad.

Take it directly to the dealer ASAP, though in a hard stop the ABS would compensate if it wanted to lock up, it is not really safe to drive like that!

What does the disc on the other side (of the truck) look like?

 

I would suggest that they take it to the dealer slowly, since they ain't gonna be able to stop good

 

Yes, that is the As Soon As Possible part...

 

yeah...BAD

looks like the whole pad is missing that that is the brake piston directly hitting rotor...

if that is the case, you need all new calipers...if this is what is happening don't settle
for simple new pads, the whole piston is corrupted if it's hitting rotor and though it
is serviceable, toyota doesn't deal in caliper subassemblies

 

Who needs brake pads!!?? LOL wow!

 

OP; it has to be nasty sounding, you did not notice that?

 

Ummm, doesn't that look a lot like a rear drum?

 

More pics please.

 

You know what? I think you are correct. The rear drums are designed to sort of mimic the look of a disc rotor...

 

I wanted to say this, but wanted to give OP benefit of the doubt...that would be quite the blunder.

 

This is what I was thinking, that's not a rotor we're looking at.
