just booked mine in. The only warning sign it says on the letter is " Some Fiesta St vechicles with RED brake calipers could experience a very slight brake fluid leakage from the brake hose connection to the Front brake caliper. If a slight leak is present,over a period of time,the brake fluid level will reduce and eventually cause the brake fluid light to come on.The time it takes for this to occur will depend upon vechicle useage and your Driving style. You may also experience a slightly longer pedal travel..
It is important that this vechicle is returned to a Ford Authorised Dealer.Your Dealer Will check the front brake Hose connections and if necessary fit new seals
