Hilux Brake thud?

Bryan,
If the noise is only there when the vehicle is cold, I would suggest its the pads mate. Some pads sit slightly loose in their calipers when things are cold. Once they get hot, they naturally expand and sit tight inside the caliper. That would be the first thing i would take a very close look at. Also possibly could be the calipers themselves OR the mounting bolts being worn or loose.
Its not uncommon for some pads to sit a tad loose inside the calipers, (I am refering to aftermarket mainly) but once the heat gets into them, they expand and tighten up which in turn will stop the noise until things cool down again.

I am amazed that they told you there is nothing they can do about it...thats just a cop out mate. They can do something to stop the noise, anything from replacing the pads to modifying the way they sit in the caliper, if your vehicle is new, get back to them and speak to the service manager about the noise, Dont just accept what they tell you..NEW CARS DONT MAKE CLUNKS !!! ..or if they do, the dealer has to fix it.....its simple.

I had a thud in my 80 Series a while back and it turned out to be a missing (yes .. missing) caliper bolt. Was lucky to get a replacement in quick time. So I would be taking a close look at the bolts and make sure they are firm. Brake pads, as explained earlier, could also be a clue.

Bit embarrassing, but when I was mmuuuccccchhh younger, my EH ute developed a clunk each time I accellerated. After much searching, testing 'U' joints, Gearbox bearings, etc, I pulled the seat forward to look for something behind and found a full can of Coke, which would just roll slowly as I accellerated and hit the rear wall of the cab. Hhhhmmmmm!

BTW, good luck finding your problem.

Happy trails, Mike.

Just a quick update, I'm not very technically clued up when it comes to vehicles, I can do the basic maintanence. Climbed underneath to change gearbox and Tcase oils, while I was under the vehicle I had a look at the left brake that was making this so called "normal" noise. The steel thing? that holds the pads in (presume caliper?) has a big bolt missing a fairly big one I might add.

I checked the right side caliper and it had both bolts. These bolts are marked with a "11" and I presume they rather important. Is this likely my problem?

Cant believe a Toyota "mechanic" could not see this!
