Soft braking after changing caliper?

you still have air in the system. re bleed it until good clean fluid comes out with no air.

Could there be any other problem that could cause this? And does the caliper adjust itself to the older pads?

it will adjust itself to any pad. once the pedal pumps the caliper to the pad, the pedal should be like it was. thats why i still think you have air in the system.

Ok thanks

Just to add to this one does the car have four wheel disc?

yes

If it has four wheel disc then you have abs how did you bleed the brakes please explain step by step?

I put the car on jacks, took the wheels off, and got a friend for pumping the brakes. after the tires were up I told my friend to press down on the brake, then I turned the bleeding screw for just a second then tightened it back. then he let go of the brake and I repeated that 4-5 times in on each side starting from passenger rear wheel, moving to driver rear, then to passenger front then driver front. I did forget to make sure the brake fluid level was full and it had gotten empty so i had to re bleed all the lines the same way.

Here is the proper bleed procedre for those brakes.
