Front

1. Jack up and support front of car. Remove wheels Mark wheel positions if locating studs are not fitted. Place support stands under lacking points





2. Remove lower guide pin retaining bolt.





3. Raise piston housing and tie back with steel wire
4. Remove brake pads

NOTE: Do not operate brake pedal while pads are removed. Clean pad mating surfaces in caliper.





5. Press brake piston back fully. Press back piston slowly using adjustable pliers, taking care to avoid damage to dust seals. Sluggish movement of the piston, as indicated by failure of the piston to return to its original position when pressed inward, may be due to oxidation. Caliper must be reconditioned if this is the case.

NOTE: Level in brake fluid reservoir may rise when piston is pressed inward, causing fluid spillage.

6. Inspect piston dust seal. Caliper must be reconditioned if dirt has entered cylinder due to damaged dust seal.





7. Inspect for corrosion or dirt between upper sliding plate and caliper retainer. Clean as required. Inspect that upper sliding plate are in position in piston housing and caliper retainer. Remove lower sliding plate. If fitted (see arrow A). Inspect guide pin dust seal. Replace seal if in poor condition.
8. Inspect disc friction surface and measure disc thickness. Replace disc if component shows signs of severe wear. distortion, variation in thickness or other defects.





9. Install new pads and lower piston housing. Tighten lower guide pin retaining bolt to 27 Nm (20 ft. lbs.). Use new bolt. Check level in brake fluid reservoir. Operate pedal repeatedly.
10. Refit wheels as per markings. Finger-tighten nuts, then torque diagonally to 85 Nm (63 ft. lbs.).
11. Test drive car.
