The defect
There may be hydraulic fluid contamination from condensation formation that can plug the ABS brake booster pump filter; stress corrosion of the master cylinder snap ring has been traced to chlorine leaking from the low pressure hydraulic hose which may cause it to break; front brake hose to tire interference which may cause failure of the brake hose.
The risk
Contamination of the hydraulic fluid can causemalfunctioning of the anti-lock brake system; low pressure hose leakage causesloss of brake fluid and also results in corrosion and failure of the mastercylinder snap ring, resulting complete brake failure; failure of the front brakehose due to hose to tire interference will cause failure of one half of thebrake system resulting in a longer stopping distance than expected.
The remedy
Replace ABS low pressure hose; rebuild master brake cylinder; inspect, service interference problems, and replace front brake hose as necessary.
