Clutch Quadrant
The clutch pedal mechanism from the donor vehicle, sierra or granada will operate with a self adjusting quadrant mechanism. This will auto adjust as things settle and stretch over time to keep the clutch working. The standard mechanism is likely to have a red quadrant. The quadrant is a toothed piece that the cable fits over, the teeth grab other parts of the mechanism to adjust. A common problem is that there is not sufficient movement of the cable with this red quadrant and so it should be replaced with a larger radiused quadrant which increases the amount of cable movement for the same amount of pedal movement.
The replacement is part number 91AB7L609AA. If you get if from a ford dealer it will be white, if you get it from another motor factors place it could be another colour.
