Installing Front Brake Disc

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Installation of brake pads with the wrong brake pad quality
  • Longer braking distance
  • More wear on brake pads

→ Only use the type-specific brake pads listed in the Porsche Parts Catalogue.

→ Replace the brake pads when the brake pad wear indicator light comes on, but no later than when there is a residual pad thickness of 2 mm on each axle.

→ Replace the brake discs on each axle as soon as the brake pad wear limit is reached.

NOTE: Removing/fitting wheels
  • Risk of damage to (ceramic) brake discs

→ Use two assembly pins when removing and fitting the wheel.

→ Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.

Do not confuse right and left brake discs during assembly!

Distinguishing characteristic: Part No.! The flat surface of the brake discs is marked with R = right or L = left.

Information 

When replacing the brake discs due to wear, the brake discs on one axle must always be replaced.

Irrespective of wear, a brake disc change can be necessary on the brake disc friction surfaces due to edge damage. In this case, only one brake disc can be replaced if the friction area surface of the other brake disc is OK.

  1. Check that all parts are in perfect condition and replace them if necessary.
  2. When replacing brake discs -2-  on vehicles with centre-lock wheel, five new wheel attachments -1-  must be fitted.

    The wheel attachments -1-  (5 x), comprising an attachment pin -1.1-  , sleeve -1.2-  and self-locking screw -1.3-  , are only available as a set for one brake disc (Part No. 997.341.901.00).

    1. 2.1. When fitting the wheel attachments -1-, always check the following: 

      All contact surfaces must be clean and free of grease.

      Tightening torque for self-locking screws -1.3-  = 6 Nm (4.5 ftlb.).

  3. Clean the levelling and centering surfaces on the brake disc and wheel hub. Then apply a very thin coat of Optimoly TA to the centering surface on the wheel hub.
  4. Fit the brake disc. Observe specified tightening torque. → 4600TW TIGHTENING TORQUES FOR BRAKE MECHANISM 
  5. Fit the brake calliper. Replace the brake calliper fastening screws each time they are removed. Observe specified tightening torque. → 4600TW TIGHTENING TORQUES FOR BRAKE MECHANISM 
  6. Fit retainer for connector for wear indicator on wheel carrier.
  7. Fit the speed sensor (ABS sensor).
  8. Position disc brake pads by operating the brake several times.
  9. Check brake fluid level and correct if necessary. The brake fluid level must be between the MAX-MIN marking. → Brake system: checking fluid level →  470801 CHECKING BRAKE FLUID LEVEL
