2012 Honda Odyssey
Original problem: Shudder while braking. Took it to the tire shop to have tires (relatively new not showing any signs of uneven wear) rotated and alignment checked. Alignment check passed but they said brakes were in need of replacement.
I ordered pads and rotors for all four corners and replaced everything. Job went smoothly, no hiccups.
I then took it out to break in according to MFG recommendations (5 x 40 to 10 stops, 5 x 35 to 5 stops, drive for 5 minutes without using brakes to let them cool).
The van does stop but the pedal felt very spongy, so I took it to a mechanic to have the brakes bled. He found some air in both rear lines. I never opened the system. I only compressed the calipers.
While bleeding the air out the pedal felt very firm. After bleeding it out it still feels spongy. There are no leaks that I can see. No fluid in wheels or on ground. Reservoir is holding steady.
As this is my wife's vehicle, it's possible it has always been like this and I am imagining things but I'd feel much more comfortable with a firmer pedal that didn't travel as far. Are there any other things I should check?
