Hi there,
Based on all the details you have mentioned, the possible problem could be a bad vacuum booster check valve, a vacuum leak, or a faulty brake vacuum booster.
1. A bad check valve may allow leakage. The check valve ensures vacuum pressure stays within the booster and does not leak back to the engine intake. It results in reducing the booster's effectiveness and also results in "crunchy" brakes, as you have explained.
2. A small hole on a brake booster hose will drop the pressure needed for the brake booster to function properly, causing warning messages and a hard brake pedal.
3. If the brake booster is malfunctioning, it leads to a faulty diaphragm or internal wear.
Please consult your trusted auto repair shop for proper diagnostic and troubleshooting repair as the best option. I hope this helps!
