I notice after I change pads and break them in, the brakes do feel a bit soft until they really get a chance to work themselves in. Takes about a hundred miles or so.
What break in procedure did you use? I assume you had good pressure before the change?
Bleeding would most likely help if you haven't done it in a while, but be careful how you bleed them as you can end up ruining the MC if you have an old one in your car. Good fluid to use is the Valvoline Super Syn brake fluid, unless you will be tracking the car. Then you might want to use a higher BP fluid, but pay a lot more money.

Re: just did brakes, not a lot of pressure (kkim)
its been about about 8-9 months, how long should u go before u bleed them?
my pads were hella low so i dunno if that effects pressure but i had more pressure before.
to brake them in i went 30-35 mph and stopped 6 times with moderate braking and then 50-60 mph 4 times with moderate braking, i didnt really get a clear answer on how to do it.
im pretty sure my MC is the one that came with the car. it has 95k miles on it and valvoline is what i use

Bleeding once a year is about right for a street car.
How did you spread the calipers when you installed the new pads? Did you crack th caliper bleed nipple or just push back with a clamp? You might have somehow introduced some air into the system if you bled the nipple. I would try bleeding the brakes.
Watch out if you use the pump and hold method w/ a buddy. I place a couple of pieces of wood under the brake pedal area to prevent the pedal going all the way to the floor when you open the bleed nipple.
With old MCs, the brake piston only gets pushed down a certain distance during normal use. After the MC get old, rust starts forming in the unused bore travel due to water absorption in the brake fluid. When you bleed your brakes after the rust has formed, the rubber seals on the MC piston gets torn as the seals are dragged throught the rusted up bore walls. You end up with a MC that will not hold pressure and will either have to rebuild or replace the MC.
hope bleeding your brakes will restore some pedal feel.
Good luck
