I have a 89 toyota camry wagon and I need to know what size the metal rear brake line is to repair a small leak in the line by the driver's side back door. They make a coupling that you can use but you need to know the line size.

 

Lines are either 3/16 or 1/4 inch.

Thanks I appreciate the response.
