    Hi all,

    Truck: 2002 Tundra Limited 4.7L 4WD

    I apologize if this is not the best Forum Topic heading or if in my searching I failed to find a similar question that had been adequately answered, but I am looking for some advice.

    My front disc brakes are squealing increasingly loudly, however, this happens almost exclusively when rotors are cool and when the truck is in reverse. I pulled the tires and found that the pads are 6mm and appear to have some life left in them. The rotors themselves look OK but have some light rust spots on them (nothing I wouldn't expect and no deep groves). Thickness of the rotors appear within spec (1.024 in or 26 mm and 1.102 in or 28 mm, in my research) and they don't have apparent warping or wear that is out of the ordinary. I drive the truck very little and live in a snowy climate.

    Does the squealing indicate that something is definitively wrong and that I should change the rotors/pads? I would call myself an intermediate DIY'er for auto repairs. I have helped others change brakes and feel comfortable with the task but I'm less experienced with the diagnostics. The rear shoes similarly have ~6mm left and I saw no apparent issues in the rear. Any recommendations would be appreciated and thanks for your time!

    If it stops well other than the slight noise when it’s cold, I wouldn’t worry about it. Sounds like you have some pads left, might as well get your moneys worth. My brakes squeak a little too when it’s cold. Some brake pads have an indicator that will rub the rotor and make a screeching noise to let you know it’s time to change them. If that’s not rubbing, don’t sweat it.

    Brake squeal is almost always related to the pads. I use Toyota pads exclusively. I find they rarely squeal. If the rotors are pretty smooth, I just change the pads. If they are grooved, they need to be turned or replaced.

    I found this great video on youtube for by ChrisFix called "How to stop your brakes from squeaking". It does a really great job of going through possible issues so I thought I would post it. I'm going to work on these this weekend. Thanks @SoCalPaul and @15whtrd for your advice.
