Bill thanks for the input, yes I have subsequently had the brake fluid replaced using a reputable shop and initially thought it had solved the issue, however it came back on drive off this morning albeit after a longer driving period (3-4 mins) and less severe. That would suggest that the interference between the pads and rotors is less than before. So when it happened, as before it felt like the braking force was applied to both sides equally and both rotors were equally hot. So that would suggest both caliper pistons are failing to release fully until the brake pedal is lightly applied. Is there any other component of the brake system which could cause residual pressure in the front brake circuit, or should I just replace both calipers?
