Help please

Intermittent squishy pedal is a symptom a failed master cylinder, or rarely a failing ABS pump assembly.

When a master cylinder with a lot of miles, or dirty fluid gets stroked completely (like when the pedal is pushed with brakes apart) the seals get dragged through any debris inside the assembly. This causes debris to get stuck around the seals, and it makes the leak(internally) sometimes and seal other times. It's a pretty common early symptom of failure.
