Brakes weird

[SleeperSolara]

Ok here's the deal wit my brakes again.
I have bought new pads for my car when i got it, and bled the lines for the brake system.
Yet te brakes pedal still feels mushy, when i press it.
I have no air in the system at all.
I read some when that mixin' brake fluids is bad.
I didn't know what was in the reserivor at first, i poured in SynPower brake fluid.
I know i need to bleed the whole system to have one fluid type of fluid in the system.
Could it be the lines or the brake booster??
What you guys think??
I read here that some guy put on a Supra brake booster and that it worked great.
Is that a striaight bolt on??

ABS always feels mushy to me hehehe. Really how many miles do you have on the pads? They can take 300-1000 miles to get going right. Mixing fluid isn't good they're different Dot ratings from what I understand. Also, I would check the lines and see if they're getting smooshy.

I think that i might have mixed the brake fluids, from the previos owner.
The lines are in good shape.
And the pads have at least some hundred miles on them.
I think it is the brake fluid.
