Need some help please identifing the chassis and brakes

i bought a kart for my son to ride around the neighborhood, and the rear caliber seals left the chat on the initial ride. looking to rebuild or upgrade, new to this style of karts.
i looked over the whole chassis for any identifacation numbers the only number it has on it is 1116 stamped on the brake mount.

Again thank you for your time and help.
