For some time now I've had an issue with a vibration or shudder in the '07 accord when traveling at highway speeds and the brakes are first applied. By the time I decelerate to 60mph or so the problem is gone. It never happens at 'around town' speeds.
I disassembled, cleaned and lubricated the brakes looking for the source. I found a caliper slide pin on the passenger rear to be frozen--and the inboard pad was unevenly worn. Also the inside surface of the rotor was uneven.
So I replaced the rear rotors and pads, installed new caliper hardware, and re-lubricated the heck out of the caliper slide pins so they move freely. I am disappointed today to find that I still have the same shudder at high speed when first applying the brake. It is less severe but still there. Any ideas on where this is coming from? --there was nothing I could find wrong visibly with the fronts.
Also, I took time to wire brush and clean the hub so the rotor would have a smooth/clean surface to rest against.
