Installing rear disc brake pads: Notes
- This can cause malfunctions.
→ Fit new expanding spring, new retaining pin and new retaining pin screw on the brake caliper.
The back of the pad backing plates must not be greased !
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) .
New disc brakes must be clean and free of grease!
The core of the warning contact line must not be left exposed! Worn insulation is not significant!
If necessary, remove a little brake fluid from the expansion tank by suction to prevent overflow when the disc brake pad is pushed back!
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 disc brake pads.
3. Install expanding spring, retaining pin -direction arrow- and lock (safety bracket) -arrow- at top of retaining pin. See Fig 1.
4. Install warning contact line at bottom of brake caliper -arrow- and warning contacts at disc brake pads. See Fig 1.
