Brake failure by model year
What owners say
Rear brake line is routed- (1) from master cylinder (2) down past driver's side front of vehicle (3) across rough body bracket. This causes the brake line to be worn in 2 places causing loss of hydraulic fluid and brake failure. There is a useless piece of spring-like sheilding which the aforementioned bracket can easily separate/slide between and begin cutting the brake line, rendering the rear brakes completely disabled and the entire braking system suseptable to the introduction of air in the lines.
When making a turn vehicle will lose braking power due to the wire coming from ABS computer and running to front disc brakes, caused brake failure.
Intermittently when the brakes are applied the pedal goes to the floor, resulting in extended stopping distance. Dealer has been notified. Throttle failes to come to idle at stop. Stays at high speed. Growling from trans-clutch area - hard shift - clutch failure.

- What is wrong
- Vehicle description: light duty passenger pickup trucks equipped with 4.3l engines. The front brake line can contact the left-hand side of the engine oil pan causing the brake line to wear to the point of brake fluid loss during brake application.
- Risk
- Brake fluid loss can reduce braking effectiveness and increase stopping distances resulting in a vehicle crash without prior warning.
- Remedy
- Dealers will inspect the clearance between the oil pan and the brake line. If the clearance is 6mm or less, dealers will install an additional brake line clip and if there was contact between the oil pan and brake line, the front brake line will be replaced.
