I mean the abs module isn't the issue of why my brake pedal is squishy, like I don't need the abs module to fix the squishy brake problem. I think there is air trapped in the brak lines or master cylinder. And how would I bleed the pv?

but I'm telling you that if there's air in the abs module it will make the pedal squishy.
- If you have performed a brake master cylinder bench bleeding on this vehicle, or if you disconnected the brake pipes from the master cylinder, or if you have disconnected the brake pipes from the proportioning valve assembly or the brake modulator assembly, you must perform the following steps to bleed air at the ports of the hydraulic component:
- If removal of the reservoir cap and diaphragm is necessary, clean the outside of the reservoir on and around the cap prior to removal.
- With the brake pipes installed securely to the master cylinder, proportioning valve assembly, or brake modulator assembly, loosen and separate one of the brake pipes from the port of the component.
- For the proportioning valve assembly or the brake modulator assembly, perform these steps in the sequence of system flow; begin with the fluid feed pipes from the master cylinder.
- Allow a small amount of brake fluid to gravity bleed from the open port of the component.
- Reconnect the brake pipe to the component and tighten securely.
- Have an assistant slowly depress the brake pedal fully and maintain steady pressure on the pedal.
- Loosen the same brake pipe to purge air from the open port of the component.
- Tighten the brake pipe, then have the assistant slowly release the brake pedal.
- Wait 15 seconds, then repeat steps 3.3-3.7 until all air is purged from the same port of the component.
- With the brake pipe installed securely to the master cylinder, proportioning valve assembly, or brake modulator assembly, and after all air has been purged from the first port of the component that was bled, loosen and separate the next brake pipe from the component, then repeat steps 3.3-3.8 until each of the ports on the component has been bled.
- After completing the final component port bleeding procedure, ensure that each of the brake pipe-to-component fittings is properly tightened.

Oh wow, I've never heard of this procedure before! So I basically do this at every brake line connection point like (master cylinder lines to pv, pv lines to brake calipers and then brake caliper bleeder screws)
