Q: I have a 2007 Honda Odyssey. When I’m stopped and push my brakes as hard as I c an, the pedal nearly touches the floor. It’s a soft and spongy pedal, as if air is in the hydraulic system. The car stops adequately without having to depress the pedal really hard.

Two dealers said the vehicle is operating properly. I don’t believe them. Should I?

A: I suspect air in the hydraulic system. My Alldata automotive database pulled up Honda service bulletin 07-045, dated March 2009, that addresses this symptom of a soft or low pedal. The likely cause is air leaking into the system from the ABS/traction control modulator control unit.

The brake system should be bled manually to see if the pedal height returns to normal. If it does, the control unit should be replaced. If the vehicle is out of warranty, the bulletin indicates the repair may be eligible for “goodwill consideration.”
