Brake System: Visual Inspection Of Brake Pads And Brake Discs For Wear
WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Risk of accidents if brake pads and brake discs are not replaced in time.
- Injury and material damage due to impaired braking effect.
→ The brake pads must be replaced when the brake pad warning indicator lights up, but no later than when there is a residual pad thickness of 2 mm.
→ Brake discs must be replaced on reaching the wear limits.
Information
- If brake pad wear is indicated by the warning light, the warning contact (sender including line and plug connection) must also be replaced.
- Replacing the warning contact can be avoided by replacing the brake pads no later than when the pad thickness is approx. 2.5 mm.
- Warning contacts must be replaced if the core of the wire is worn. Worn insulation is not important.
- However, if only the plastic part of the warning contact is worn, there is no need to replace it.
- Visually inspect the brake pads for wear -arrows-
(wear limit 2 mm).NOTE: From model year 2003 - model year 2007 → Checking thickness of brake pads front brake pads or Checking thickness of brake pads for rear brake pads.
As of model year 2009 → 463602 CHECKING THICKNESS OF DISC BRAKE PADS AT FRONT → 463802 CHECKING THICKNESS OF DISC BRAKE PADS AT REAR
- Carry out a visual inspection of the brake discs for wear → WM 4600TW Technical data/test values and brake wear limits .
