Im just sharing an image sent to us by a colleague, this image is of a brake caliper on a toyota 4wd after a heavy 4wd session, keep in mind the extra costs associated with this kind of driving if your thinking of buying one or doing heavy 4wd’ing, this type of driving adds a substantial amount to the cost or repairs & maintenance, it’s not cheap, & it’s not good for your vehicle. Thanks to Matt Stokes for the image & allowing to share.
