WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

Before installation of the brake pads, check the wear of the brake discs. For minimum thickness of the brake discs, see 2. CHECKING BRAKE DISCS FOR MINIMUM THICKNESS . See WEAR LIMIT TECHNICAL DATA AND SPECIFICATIONS - BOXSTER S .
If necessary, press the piston back to its original position using the resetting fixture.
Fit new damper plates in the pistons. Remove protective film from the damper plates before installation.
Insert the brake pads. Ensure correct brake pad quality.

NOTE:

The brake pad quality on the front and rear axles is identical. The pad backing plates (rear side of the brake pads) must not be greased.

Fit new expanding spring, new retaining pin and new retainer (arrow). See Fig 1 . These parts are available as a repair set and must be "renewed" each time the pads are changed.
