Have owned this for 12 years and 86,000 trouble free miles until eight months ago. Due to age and recent surgery I no longer do my own maintenance. Left or right rear brakes lock usually when brakes are most needed, i.e. quick freeway stop. This tends to cause swerving. Once caused 140 degree spin. Six mechanics including myself have attempted to correct. Following replaced: Rear brake shoes, wheel cylinders, hardware, rubber lines, drums. Front rotors, calipers, pads, rubber lines. Master cylinder, proportioning valve. After all this, rear brakes still unexpectedly grab and usually only one. Now have brake malfunction light beginning after front brakes overhauled.

    Have the metal brake lines been carefully examined for compression or other damage?
