Brake feels mush only at low speed(local driving)

[pwu]

Everytime I had to slow down or stop my 4 runner at low speed(5mph-45mph) is to slowly depress my brake padel half way then the brake stops solid. If I slam on the brake, It feels like it has air in the system.

I took it to a local autoshop and they replace MC, rotors, pads and did all necessary adjustments. Nothing worked.

But at freeway speed, the brake feels much better and stops OK from 70mph to 0mph.

The only thing I haven't look at is the booster.
