Not sure about Tacos but my Tundra and most others had severe rotor warping
issues.  Best best is to buy a high quality replacement rotor and pads for
both front wheels.  Don't go to Toyota - they'll rip you off.  It's an easy
one hour DIY job.  Premium rotors/pads cost me about $175 I think.  Jack
front end and put on jack stands.  Remove wheels.  Disconnect spring clip
holding brakelines.  Remove caliper bolts and support calipers with bent
piece of coat hangar (don't want to break flexible brake hose from hanging
weight of caliper).  Pull rotor and replace.  If rotor seriously warped may
need to hit it with hammer around the edges to loosen it from wheel flange
assembly (don't damage that part - the rotor is throw-away part).  Use
c-clamp to compress piston and install new pads.  Install calipers and
wheels.  Don't forget the spring clip for hoses.  Check fluid level and
replace if necessary/desired.  No need to bleed if system not opened.  Pump
brake pedal to ensure good pedal response.  Remove jackstands. That's it.
