When owners reported it

Service brakes, hydraulic:antilock/traction control/electronic limited slip
Model years: 2000
Problem: Vehicle description: s -trucks equipped with 2 wheel drive. These vehicles may have had the right-hand antilock brake system (abs) module feed pipe and/or brake crossover pipe tube nuts tightened without seating the pipe-flared-ends enough to withstand normal assembly and vehicle inputs without partially unseating. This does not comply with requirements of fmvss no. 105, "hydraulic service brake normal, emergency, and park braking performance."
Risk: If this occurred, the seating seal could be broken during vehicle assembly, or from early road inputs or brake fluid cycling, and a leak could occur increasing the brake stopping distance.
Fix: Dealers will inspect the brake pipe union for signs of brake fluid, and if necessary, install a new brake pipe union.
Service brakes, hydraulic:antilock/traction control/electronic limited slip
Model years: 1995, 1996
Problem: Vehicle description: certain 4-wheel drive pickup trucks and sport utility vehicles equipped with abs (antilock braking system) manufactured from september 1989 through august 1996. Under certain driving conditions the switch which signals the abs system whether the vehicle is in 2-wheel or 4-wheel drive can malfunction causing increased stopping distances during abs stops while in the two-wheel drive mode.
Risk: If this occurred at a time when minimum stopping distance was required, a vehicle crash could occur without prior warning.
Fix: Dealers will replace or repair the 4-wheel/2-wheel drive switch.
Service brakes, hydraulic:foundation components:hoses, lines/piping, and fittings
Model years: 1998
Problem: Vehicle description: light duty pickup trucks and multi-purpose passenger vehicles. A fatigue fracture of the rear axle right-hand brake pipe can occur causing a slow brake fluid leak resulting in a soft brake pedal. If the brake pipe breaks, the driver would experience a sudden drop in the brake pedal, the instrument panel brake light would illuminate, and there would be a loss of rear brake performance.
Risk: Partial loss of braking at a time when minimum stopping distance was required could result in a vehicle crash.
Fix: Dealers will inspect and replace the brake pipe.
Service brakes, hydraulic:pedals and linkages
Model years: 1995
Problem: The brake pedal pivot bolt was started in the weld nut, but was not torqued correctly causing the bolt to disengage from the weld nut.
Risk: This condition can result in a total loss of brakingcapability.
Fix: Dealers will inspect for hand-started brake pedal bolts and torque them to correct specifications.
