While attempting to stop our 2001 Odyssey in my son's school parking lot the brake pedal--without any prior warning--went to the floor and I coasted past my intended stopping point by about 20 feet. Luckily no person or vehicle was directly in front of me at that time. I was able to restore brake function by pumping the brake pedal. The next day my mechanic examined the brake master cylinder and found brake fluid leaking into the brake booster. He explained that when the seals on the master cylinder leak the fluid collects in the brake booster. To correct the problem he had to replace the entire master cylinder. He thought that this problem was very very unusual. He specializes in imported vehicles and had never before replaced a leaking master cylinder on a Honda Odyssey of any model year. Our Odyssey is a 2001 model, is very well maintained and has been driven less than 64,000 miles.
