Hand brake forget to release foot brake failure

Hand brakes generally brake the rear wheels. Santana's brakes are usually front discs and rear drums. Handbrake did not release to drive, may be because the brake rear drum of the thick iron bar (connecting the handbrake puller and the rear drum of the bar) did not return to the position, you can put down the handbrake directly drive to try. In the process of driving it will slowly return to the position, or put a longer time, it will also return to the position. If you are not sure, go under the car and pull the bar back.

Based on what you've said, it looks like your footbrake is only braking the rear wheels, not the front

Suggest adjusting the front brakes tighter. It is best to check the front wheel brakes. The handbrake has been left on for so long that the brake drums must be rubbing badly and the braking effect on the rear wheels is also affected. It's best to check the rear brakes as well.
