Hi there. From the description you have provided, your vehicle’s hard brake pedal is a safety concern. It could be, the power brake booster check valve is faulty. It could be, the brake booster itself, is at fault. A hissing sound may be heard, when the brake pedal is applied. It could be, low engine vacuum supplied to the brake booster. I recommend having your vehicle’s hard brake pedal be diagnosed and repaired by a certified technician from YourMechanic.
