DIY Mechanic Check: Before Visiting a Shop
- Visual Inspection: Press the brake pedal in park with engine running. If a continuous hissing sound comes from beneath the driver dashboard, the brake booster diaphragm has failed.
- Check Fluid Levels: Verify engine oil level, coolant level in the reservoir, and transmission/power steering fluid condition.
- Replicate Under Control: Note whether the sound happens when moving or stationary, and if turning the steering wheel alters the pitch.
