1967 GMC E5500 Recalls (5)
- Campaign:
- 69V039000 on 10/11/1979
- Component:
- Service brakes, hydraulic:foundation components:master cylinder
- Affected:
- 163,493
- Notes:
- Possibility that seal on piston in master brake cylinder may, after extendedusage, allow brake fluid to pass seal permitting brake pedal to be pushed tofloor in a slow gradual stop or upon the first ap- plication of brakes aftervehicle has been standing for a period of time.is also a possibility thatinner liner of vacuum hose which connects to brake vacuum booster may collapse,causing loss of power brake assist.(correct by installing new parts in brakemaster cylinder and modifying vacuum hose rout- ing.)
- Campaign:
- 67V007001 on 10/11/1979
- Component:
- Steering:hydraulic power assist:hose, piping, and connections
- Affected:
- 413
- Notes:
- Possibility that, during a full right hand turn, the power steering pressure lines running to the power cylinder may become scored or partially crushed through interference with a clamp on the power steering power cylinder piston rod.this may result in loss of power assist, but manual steering control would be maintained with higher efforts.also during a full right hand turn, the left front tire could contact the power steering power cylinder ball and studor its clamp.this chafing could cause tire failure.(install new power steering pressure lines, reposition the ball stud clamp, and readjust the front wheel stops to eliminate the interference conditions.)
- Campaign:
- 67V101000 on 10/11/1979
- Component:
- Service brakes, hydraulic:power assist:vacuum
- Affected:
- 15,382
- Notes:
- Possibility that improper length hydraulic brake hose may have been inadvertently installed on one or both sides of the front wheel.brake hoses that are too long will contact the tire or shock absorber during a full right or full left turn.this could chafe the hose and could cause a rupture and loss of braking action.(inspect and install correct length hose as required.)
- Campaign:
- 67V089000 on 10/11/1979
- Component:
- Service brakes, hydraulic:power assist
- Affected:
- 14,012
- Notes:
- Possibility that a lack of brake power assist may be caused by a defective check valve or by possible interference between the booster actuating huband dust seal retainer on the firewall.loss of power assist will result in higher than normal brake pedal effort and make it difficult to stop within a satisfac- tory distance.(inspect, test, and replace parts as required.)
- Campaign:
- 66V033001 on 10/11/1979
- Component:
- Steering:linkages
- Affected:
- 495
- Notes:
- Possible installation of incorrect steering pitman arm and drag link assembly. this could cause a loose- ness in the drag link to steering arm connection, which could result in the drag link becoming disconnected from the steering arm, causing a loss of steering control.(inspect and install correct pitman arm and drag link assembly as necessary.)
