vehicle meshes move incorectly

Hello guys, i saw that front brake calipers on gavril grand marshall doesnt move as supposed to - half caliper goes to disc and half leaves in place resulting in stretching.
On gavril d series i saw that front driveshafts goes faster than wheels turning, resulting in driveshaft going more than wheel.
On ibishu covet brake caliper problem is too, but more like the d series - mesh doesnt strech, but 'de-syncs' from disc.
