Having the brakes fail while driving is a dangerous and horrifying experience, especially when traveling on an interstate highway or other high-speed roadway.

The National Safety Council has these tips for coping with brake failure:

• At the first sign of trouble, try not to panic. Instead, work the vehicle into the right lane and then toward the shoulder or, if possible, toward an exit. If it is necessary to change lanes, do so smoothly and carefully, watching mirrors and the traffic around very closely.
• Remember to use the directional signal to indicate intentions to other drivers. When you reach the right lane turn on the car's emergency hazard lights.
• Let the car slow down gradually by taking foot off the gas pedal. Steer as the vehicle slows and shift the car into a lower gear to let the engine help slow the car.
• Once off the traveled roadway, shift into neutral and gradually apply the hand brake until the vehicle stops. If that brake also has failed, direct the car onto a soft shoulder or rub the wheel against a curb which will help slow the vehicle down. Get the car off the roadway and to a safe place to avoid stopping traffic or being involved in a rear-end collision.
• When safely off the road, put out reflective triangles beside and behind the vehicle to alert other drivers; keep the emergency flashers on.
• Professional assistance will be needed. Raise the hood and tie something white to the radio antenna or hang it out the window so police officers or tow truck operators will know you need help. Don't stand behind or next to the vehicle; if possible, stay away from the vehicle and wait for help to arrive.
• All interstate highways and major roads are patrolled regularly. Also, some highways have special "call-for-help" phones. If you have a CB radio or cellular mobile phone call for assistance from the vehicle.
• It is inadvisable to walk on an interstate. However, if you can see a source of help and are able to reach it on foot, try the direct approach by walking, but keep as far from traffic as possible.

A final caution, do not be tempted to drive your vehicle, no matter how slowly, without brakes. Call for help to get the disabled vehicle towed and then have the brakes repaired by a qualified mechanic.
