Brown foam in radiator overflow

Start by reverse flushing your cooling system using a quality flushing agent.
Brown sludge can be corrosion or it can be oil from a leaky head gasket.
After cleaning have your coolant tested for combustion gases to see if it may be a head gasket issue. If the brown comes back it may not be a combusion chamber leak but one between an oil passage and the coolant.

Thanks Speedy, I'll try those things and see what happens.
