Changed front brake pads on 99 daewoo matiz but they still feel soft also how do i bleed the brakes on it

Anything to do with brakes requires expertise. You don't want to mess this up because the end result is an accident, injury and/or death.
It is easier to do if you can get the car up in the air a bit and with the wheel removed. It can be done without raising the vehicle and removing the wheel but you'll have less room to work in. If ou do raise the car and remove the wheel be sure to use jack stands not just a jack (Never get under a car that is beng held up with just a jack) The basics are you always have to make sure you brake fluid reservor is filled. Start with the brake farthest from the brake fluid reservor. Have someone pump the brakes and then hold the brake pedal while you open the bleed screw on the brake. FYI: You should put a thin clear plastic tube over the bleed screw and the other end into a bottle with some brake fluid in the bottom (lkeep the tube under the fluid so you don't accidentially let air enter the system). The pedal will sink to the floor as you open trhe bleed screw and your friend HAS to hold it there until you get the bleed screw re-tightened. Then you tell you friend he can let the pedal up and repeat the process. Note: If the brakes do not feel stiffer from you just pumping them you may have a more serious problem than just air in the system. Remember to keep checking the brake fluid reservor and refilling it or you will end up adding more air to the system and have to repeat the whole thing. Also be sure to use the correct type of brake fluid. Also the brake bleed screws can be broken off or rounded off if you don't use the proper sized wrench as they usually are very tight. DON'T EVEN THINK ABOUT USING PLIERS OR VICE GRIPS. If you are unsure of what you are doing get a friend who has some experience or take it to a shop.
