Hey guys this is my first time posting on here so g'day, I've recently bought an FZj80, I'm a first-year mechanics apprentice but this problem has stumped me, whenever the car is driven in hot weather and the brakes hit a certain temperature the calipers start engaging slowly to the point where its undrivable, I'm planning on putting new pads and discs on it once I can afford them and also do a full caliper rebuild but also heard it could be something to do with my brake lines, I don't think its the master because as soon as the brakes have some time to cool down they're perfectly fine again. if anyone here has any ideas about what it could be. first time it happened was Christmas day, pads and discs aren't in the best of shapes as well but other than that the car is basically bone stock. I'm also thinking about replacing the brake lines but planning on doing a 2-inch lift on it later on, I don't know if ill need extended brake lines or not for that yet and if so is it alright to put extended brake lines before the car gets a lift
