thanks for that my dad said that its definitely something with the brakes bc they were new brakes and it was as if the two front ones were burnt like charcoal would burn he said maybe something that relays from the front to back brakes?

Could be the brakes are locking up-due to a caliper piston not retracting or a collasped brake hose

Inspect/test the brake system that's the only way to find out
