Removing and Installing Rear Brake Pads

Removing and installing rear brake pads
Tools





Preliminary work
1. Remove wheel.

Removing rear disc brake pads

WARNING:
Danger of accident if brake pads of the wrong quality are installed.
^ This can result in longer braking distances and more wear.
^ Use only the type-specific brake pads in the Porsche Spare Parts Catalogue.

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!





1. Remove lock (securing clip) -arrow- at top from retaining pin and remove retaining pin -direction arrow- inwards
2. Remove warning contact line from brake caliper and expanding spring. Remove warning contacts from the brake disc pads.
3. Remove expanding spring.





4. Place piston resetting fixture (replaces P83) NR.144, see Workshop Equipment Manual, Chapter 2.4, on brake caliper between the disc brake pads and push the pads back evenly -direction arrows-.
5. Remove disc brake pads.

Installing rear disc brake pads

WARNING:
Danger of accident if old parts are fitted on brake caliper.
^ 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!
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!

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.
4. Install warning contact line at bottom of brake caliper -arrow- and warning contacts at disc brake pads.
5. Press the brake pedal several times while the car is stationary to position the pads on the brake disc.





6. Check brake fluid level and correct if necessary. The brake fluid level must lie within the - MAX - MIN marking.

Bedding in the brake pads
New brake pads require a bedding-in period of approximately 200 km! Only then do they achieve their best friction and wear coefficient! During this period, the brakes should only be subjected to full stress at high speed in emergencies!

Subsequent work
Mount wheel.
