OTC's One Man Brake Bleeder Hose is designed to allow one person to remove air from brake systems one wheel at a time. One end of the specially designed bleeder hose simply slides onto the bleeder screw then tangs and a sliding lock washer hold the hose securely in place to prevent leakage. A check valve on the other end of the hose prevents air from entering the brake system when pumping the brake pedal. One person operation means there's no need for an assistant when bleeding brakes. Value is at the core of the OTC tool and equipment portfolio. For a simple repair or the most complex drivability concern, these award-winning tools universally solve problems faster, and at better value, than any other product line available. Whether it's a specialty tool or unique piece of service equipment, OTC provides top solutions to modern automotive service challenges while increasing technicians' productivity and shop profits.
