The brake lines from engine to the back of the car need to be replaced because one of the attachments (holding the brake lines in place underneath the car) got rusted and corrosion. Then it caused the brake line to get rusted and brake fluid started to leak pretty bad. Is it normal for the brake lines to get rusted"? should I report to Hyundai" the brake fluid reservoir went empty so quickly and I found the leaking spot. It squirts pretty bad when I apply the brake pedal. The leaking spot is underneath the car where the back seats are located. I need some advise before I start doing something. Thank you.

I was driving my vehicle under normal conditions on a major highway. Upon approaching an exit I applied the brakes to reduce my speed. The brake pedal went all the way to the floor and consequently I engaged my emergency brake to stop the vehicle. The brake warning light did not come on until I brought the vehicle to a complete stop. No accident ensured as a result. I had my vehicle towed to a repair facility where repairs were made. Repairs consisted of a complete replacement of all brakes lines since they were all rusted and corroded. Old parts are not available. A few months prior to this incident all the power steering lines required replacement due to rust and corrosion. The complete exhaust system currently requires replacement due to rust and corrosion (system is leaking).

Problems with brake equipment on Hyundai Sonata. While braking the consumer heard a noise front he rear of the vehicle. Over time the noise progressed into a grinding noise. The vehicle was taken to the dealer at 19400 miles and the consumer was informed that the rear brake pads needed to be replaced. The technician showed the consumer the corroded and dirty surfaces that the brake pad holder rested on. This surface is horizontal and does not allow the surface to drain or clean itself. The brake rotors were replaced by the dealer but the consumer was charged $160. For the labors and brake pads. The consumer believes that having the brake replaced at 19000 miles is unreasonable and request reimbursement.
