Why change the Extended Brake Lines? Every time you apply pressure to the brake pedal, your brake line rubber expands a bit due to the high hydraulic pressure (volumetric expansion) used during braking, which eventually causes the brake lines to ‘soften’, increasing with age, resulting in a soft spongy feel in the brake pedal.
When you have that feeling, then it is possible that new brake lines are required. If a lift has been fitted to the vehicle with already softened brake Lines, this can further result in brake line failure. Brake Lines Kit Brake Hose Kit Braided 105 Series ABS 3Inch Lift
