06 Accord Value Package sedan, front disk, rear drums, 2.4L, automatic. At about 65K miles, steering wheel would vibrate and you could feel a shudder when braking from speeds above 50mph. Changes pads and rotors (front, rears are shoes), problem persists. Checked runout on new rotors - none. Cleaned and lubed caliper slider pins, flushed and bled brake fluid, tires are new, alignment is fresh. Car doesn't pull when braking, just this shudder and vibration until the car slows below about 40mph, seems to get worse the hotter the brakes are. I've checked front end components, everything appears tight, no movement in the wheels like a bad bearing. Car now has 77K on it. It's been to the dealer twice, but they only go out and drive it on 35mph surface streets for five minutes and come back with no trouble found reports even though I've asked them to please take it out on the Interstate and, when safe, to brake fairly hard (or to ride with me and I'll demonstrate it) but they claim it should do it at all speeds if there is a problem.
I'm at a loss where to go next. I'm kind of down to thinking it might be a bad caliper that is binding up the piston but I've got no uneven pad wear and didn't on the old pads with 70K miles. Any help is appreciated and thanks so much for this great forum!
