INFECTIOUS AGENT. Viral pathogens are the most common cause of respiratory infection in travelers; causative agents include rhinovirus, respiratory syncytial virus, influenza virus, parainfluenza virus, human metapneumovirus, measles, mumps, adenovirus, and coronavirus.
Find a repair shop that will cut out the bad section of metal brake line and insert a new section. Some shops will want to replace the whole brake line, but that can be more expensive and not needed in many cases. You'll pay $300 or so depending on the location of the leak.
The make of the car is irrelevant. The location of the leak is what matters. If it is a leaking rubber hose if should cost next to nothing. If it is in the radiator it will cost, at a guess, about Â£150. If it is a leaking cylinder head gasket it will cost several hundreds. Ask for an estimate first, from at least three garages, and plead poverty. Include a Toyota garage in the list.
