Diagnosing Brake Issues: Master Cylinder or ABS Modulator?  @ericthecarguy
Uploaded December 2025 | Updated September 2026, 2 weeks ago
This is the first time I’ve seen this, but that doesn’t mean it’s the first time this has happened. My wife’s 2012 Honda Odyssey with about 194K suddenly developed a very soft brake pedal one day. Watch the video to see why that happened, and how you can diagnose and repair this problem yourself.

Thank you for watching!
