An essential part to have functioning so you can stop is your Buick brake lines and hoses. These auto parts are made specifically for your make and model so the correct amount of hydraulic pressure can be received by the calipers and your vehicle will be effectively slowed down. Each brake line and hose for your Buick is made specifically for one application. This is an auto part that should never be interchanged with any other than for its listed intentions. The hydraulic fluid that travels thru them is at high pressure when the brake pedal is applied. If there is even a small imperfection in the seals or the brake line and hose themselves, brake failure can and will occur on your Buick. All replacement Buick brake line and hoses are made to meet or exceed original equipment specifications. This is one of the parts where a cheap replacement in order to save money is highly discouraged.
