Check your brake system if it lacks vacuum pressure. If it, then you have to put sufficient vacuum pressure on its need. However, if it is below 18 inches, then it needs more air. To do this, you will need to install a vacuum pump or can go for servicing.

Faulty Starter Cable and Battery Terminal

A faulty starter cable is one of the most found causes of a hard brake. If your starter cable gets disconnected from the battery terminal, it stiffens the brake. If your car makes loud clicking while turning the key, your starter cable is damaged.

Check the circuit thoroughly battery, cables, fuses, relay, and ignition switch. If you find corrosion in the cable, then change or fix it carefully. Fixing the cable will fix your hard brake pedal car and won’t start.

Apart from these, if your braking parts are broken or the brake pedals are overheated, it can cause the brake pedal to be stiff, resulting in the car won’t start issue.
