    Hello!

    I was wondering if anyone had had a similar issue with their 355.

    The brake pedal is very firm and the brakes barely work, suspected that the servos are not working.

    At the same time the brake lights are on constantantly even if the brake pedal is not depressed.

    The radiator fan fuse was badly burnt on the casing but the fuse was intact

    The pop up headlights are struggling to come up but very noisy.

    All these issues happened at the same time.

    The brake warning light and Abs warning light also have come on.

    I am guessing they are all interlinked given they happened together, replaced the fuse but as the original wasn't popped it made no different.

    Anyone had a similar experience!?

    Thanks in advance

    Do you mean the brake lights at the rear of the car? Is your pedal at a normal height? i.e. the same level as the clutch pedal. Do you have an air gap between the pedal and the pedal switch with the pedal not pushed?

    The brake warning light comes on for the follow on a '95 car:

    Low brake fluid quantity
    Front brake pad wear
    Low ABS pump pressure

    Could be a faulty pressure switch, but with all the other symptoms, I'd say unlikely. Is the ABS pump running constantly or not at all... or does it cycle on and off?

    There are two radiator fans. Which fan fuse was burnt? The burnt fuse casing suggests there is a high resistance between the fuse prongs and the relay board.
