FINALLY, I found a solution to get a better brake pedal feel and stopping power from the wimpy stock 3rd gen odyssey brakes; stainless steel braided brake lines.
Some people here have installed the pilot brakes on their odyssey. I tried it after these people made claims that their heads are hitting the windshield after installing pilot brakes lol not literally, but you get my point. (also placebo effect)
BIGGEST WASTE of time and money. The brake felt WORST with the pilot brake upgrade. Why? Now you have bigger calipers, brake fluid needs more time to get to the pistons. This results in more pedal travel than stock and no braking performance increased whatsoever. Going back to stock was better after the pilot brake upgrade.
I thought stainless steel lines weren't going to do anything, especially with just the front stainless steel braided lines installed. I went ahead and installed just the FRONT lines with Dot 4 brake fluid. Now, I finally have better brake pedal feel and also better braking power. This is because the stainless steel braided lines do not flex/expand when you brake, fluid travels faster to the brake pistons and gives you better braking performance. I plan on installing the rear lines as well.
No need to upgrade to bigger wheel setup with these lines. With the pilot brakes, you need to upgrade your stock wheels too.
I recommend getting the clear stainless steel lines so you can easily inspect them.
Here are videos on replacing the brake hoses and bleeding brakes. Stainless steel lines and Dot 4 brake fluid are linked in the videos. They are available for all of the odyssey generations.
