Removing and Installing the Front Disc Brake Pads

Removing and installing the front disc brake pads

Warning! Danger of accident if brake pads with the wrong brake pad quality are installed!
^ Use only the type-specific brake pads specified in the Porsche Spare Parts Catalogue!

Removal
^ Remove wheel!
^ The core of the warning contact wire must not be left exposed! Worn insulation is insignificant!
^ If necessary, remove a little brake fluid from the expansion tank by suction in order to prevent spilling when disc brake pad is pushed back!





1. Remove fastening screw at retainer pin. Subsequently screw in auxiliary screw M8. Hold down expanding springs with -a screwdriver- and remove retainer pin.
2. Remove warning contact wire at brake caliper and expanding spring. Remove warning contacts from brake disc pads.





3. Place piston resetting fixture 144 on brake caliper between the disc brake pads and push pads back evenly -movement arrows-.





4. Remove disc brake pads.

Installation

Warning! Danger of accident if old parts are fitted on brake caliper!
^ 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! New disc brakes must be clean and free of grease!
^ Check disc brakes for wear.
^ The core of the warning contact wire must not be left exposed! Worn insulation is insignificant!
^ Use new repair kit!

1. If necessary, push brake piston back into its original position using the piston resetting fixture 144.
2. Install new disc brake pads.

Note!
^ Make sure that the retaining pin is inserted in the correct position! The side levelling surfaces prevent the retaining pin from twisting in the brake caliper!





3. Install expanding spring. Centre 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 install fastening screw at retaining pin with specified tightening torque (30 Nm (22 ft. lbs.))!
4. Install warning contact wire at disc brake pads and expanding spring.





^ The cable guide in the expanding spring must be at the bottom!

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 be between the -MAX-MIN marking-.
7. Mount wheel.
^ Use correct tightening torques!

Bedding in the brake pads
New brake pads require a bedding-in period of approximately 200 km! Not until then do they achieve their best friction and wear coefficient! During this period, the brakes should be subjected to full stress when travailing at high speed only in emergencies!
