My 2000 Honda Accord with 135k miles has drum brakes on the rear, disks on the front with OEM Honda pads and original rotors. Brakes work fine except after a lengthly (1hr or more) highway cruise. If I have to hit the brakes agressively for a traffic slowdown it momentarily pulls to the right then goes straight. After that it stops straight until you have driven for an extended time again. I suspect one of the calipers is getting the pads moved further apart during the long drive and they have to travel slightly further before contacting the disk thus delaying the braking on that side. There is no vibration or pulsation like a warped rotor would cause. Has anyone experieced this issue and know the fix?
