Brake Master Cylinder problems of the 2008 Honda Odyssey

Dangerous braking due to soft brake pedal; relative to NHTSA campaign number 10v098000. This recall has been previously addressed on this vehicle, however, the problem persists. Increased stopping distance, vehicle has a tendency to roll through stop signs or stop lights if driver is not careful to begin stopping earlier than normal. Vehicle has a new master cylinder installed yet the problem remains. Elevated vehicle on jack stands to check caliper function. Discovered only two wheels are braking. With engine running, while on jack stands, I had my wife press and hold the brake pedal while I attempted to roll each wheel; the left front and right rear wheels rolled freely with brake pedal pressed, and the right front and left rear were unable to be rolled with brake pedal pressed. With brake pedal pressed and a proper bleeding sequence, I opened the bleeder valve on the calipers. The left front and right rear calipers exhibited no fluid pressure. It is known this vehicle braking system is made up of two hydraulic circuits linking the left front with the right rear, and linking the right front with the left rear. Something linked to the previous recall is causing the brake system to fail and continue to exhibit the same problem as before.

I have read that a lot of 2008 Honda Odyssey have a brake pedal that goes to the floor and my brake pedal does the same. I had to drive very slow so the car will stop, pedal goes to floor before slowly stopping. Honda dealer replaced the master cylinder $600. 00 drove home, went back next day because it was not the right fix. Dealer had it all day, said he talked to Honda tech dept. On phone checked computers and other things as per tech advice, every thing is working as it should, no cost to me but brake pedal still goes to the floor. My wife can not drive this car, it is parked till you can tell me how it can be fixed and safe for us to drive and every one on the road. I could not live with myself if my family were hurt or if this 2008 Honda Odyssey could not stop and hurt or killed other people. Please make Honda fix these brakes.

We purchased our 2008 Odyssey on 7/5/08. After driving it a while we noticed the brakes appeared to be soft and spongy. When I finally took it in for service, I was told it needed a new master cylinder (at 2800 miles), which they replaced. After I picked it up, I drove it a few miles and the brakes still felt soft and spongy, so I drove back to the dealership. The service manager then drove the car and told me 'that's the way the Odyssey brakes are. ' while on a trip we took it to another Honda dealer and was told the same thing. We have a ridgeline and those brakes are not soft and spongy. It appears that many other Odyssey dealers have the same problem.
