Gs, sorry I missed the part, you need to completely stop the engine to a off state, Remove the key and start the pedal kick and depress the brake pedal several times around 40 times until you find no vacuum is left in the booster. And Stop for a minute, then again start to push the pedal this time you will a certain resistance , Now visually see what distance is the resistance felt, is it halfway mark or at the 3/4 mark, if it is at 3/4 mark then you need to the brake overhaul ie Complete remove the brake fluid and have an inspection of the pads also, including the parking brake pads. Now replace with new fluid after the complete bleed process is over. I will give you an hint: When a pressure in power supply system is released the reaction force becomes light and the stroke becomes longer.
Now at the second stage, Push the ignition to on and now depress the pedal to 20 times. Give it a minute and now check the brake reservoir in the engine bay, you will see it getting up to to the brim and it will be a slow process that the level will start to decrease. Go back to your car . Now start your car, depress the pedal to a few times. And then give a final release, Take a test drive in a less traffic or congested area or empty traffic road, and do a sudden burst of acceleration and then brake isntantly again do a burst, Till you feel the spongy feeling on brake is getting dissappeared and you will get a firm braking environment result. let us know.
