Installing front brake pads: Notes
- This can cause malfunctions.
→ Fit new expanding spring, new retaining pin and new retaining pin screw on the brake caliper.
Do not grease the back of the disc brake pad !
The new disc brakes must be clean and free of grease!
Check disc brakes for wear. For wear limits see Technical Data → 46 TW Tightening torques for brake mechanics - as of MY 2003 (All Models Except Cayenne S TIO Titan) .
The core of the warning contact line must not be left exposed! Worn insulation is not significant!
Use a new repair kit!
Observe correct tightening torques → 46 TW Tightening torques for brake mechanics - as of MY 2003 (All Models Except Cayenne S TIO Titan) .
1. If necessary, push brake piston back into its original position using the piston resetting fixture (replaces P83) NR.144 , see Workshop Equipment Manual, Chapter 2.4.
2. Fit new disc brake pads.
- Make sure that the retaining pin is inserted in the correct position. The flat side surfaces prevent the retaining pin from twisting in the brake caliper.
3. Install expanding spring. center the retaining pin in the bore with the M8 auxiliary screw. To do so, push retaining pin back with auxiliary screw and push retaining pin through. Remove auxiliary screw and fit fastening screw at retaining pin with specified tightening torque → 46 TW Tightening torques for brake mechanics - as of MY 2003 (All Models Except Cayenne S TIO Titan) .
4. Install warning contact line at disc brake pads and expanding spring -arrows- . The cable guide in the expanding spring must be at the bottom! See Fig 2.
5. Position disc brake pads by operating the brake several times.
6. Check brake fluid level and correct if necessary. The brake fluid level must lie within the MAX - MIN marking. See Fig 3.
