I would first check to make sure that your vacuum pump is working.

You can unfasten the brake booster vacuum hose from the brake booster while engine is running and test with finger for a suction sensation.

Ok, the brakes on these cars are extremely simple, and extremely high quality.

If the pedal is mushy, you have air in the system.

If the pedal drifts to the floor, you have a bad master cylinder.

If the pedal is hard to press with the engine running, you have bad vacuum supply, or a bad booster.

That’s it.

If a wheel is dragging, you could have caliper issues, flex hose issues, or rarely master cylinder issues.
