Is your vehicle over 5 years old? If so you should consider replacing your rubber brake hoses. Top rubber manufacturers suggest that rubber lines decay after 3-5 years! But even replacing them sometimes isn’t enough because the rubber has a shelf life of about 7 years.
This means that even if you go to your local auto parts store and buy a replacement hose you may be replacing your bad lines with expired rubber because there are no regulations requiring stores to throw out old rubber stock.
Hoses purchased from Shamrock Tube and Hose are made when you order them from new stock, just check the date on the hose. This means that you are replacing your lines with the very best available to get a long life for your vehicle.
