They swell if they get contaminated with any type of petroleum product.
I would replace the master, ALL rubber lines and all wheel cylinders.
Also you will want to look over the steel lines REALLY close. If they
look rusty replace them. Being a popular vehicle there are all stainless
kits available as bolt on items to replace the lines. Not really cheap
bust for a pony car I'd spend the money.
Keep in mind that a car is rather difficult to stop if the brakes fail.
