Example complaints

2000: “I have owned this truck since may, 2001 (use with approx 10k miles). I took it to have it serviced because the vehicle was losing brake fluid and I could not find a leak at any of the wheels or the flexible lines to the calipers. The shop I took it to called me to tell me that one of the brake lines had cracked where it had rusted just below the master cylinder next to the firewall and that he had repaired that section of the brake line. He further indicated that I would likely have future problems with the same issue because the brake lines all appeared to be very rusty. …”
