Default Brake pad procedure for 2011 Cayenne

Has anyone done a Pad change on a 2011 6-cyl Cayenne ?
I cant stand the brake dust anymore and have purchased low dust pads
Have done the pad R&R on both my 996TT and GT3 (very straightforward) but dont know if the Cayenne is different. If you've done a pad change and can share the procedure and watchouts I would really appreciate it !

Thanks in advance

I can't imagine it being too much more complicated. Maybe check Renntech to see if anyone has done it?

Removing and installing front disc brake pads


Tools
Designation Type Number Description
piston resetting fixture (replaces P83) Commercially available tool Nr.144
assembly pin VW tool T10439









Preliminary work

Lift the vehicle.
Remove the wheel. Use assembly aids (assembly pins)


Brake disc and calliper





Removing front disc brake pads

NOTICE

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.


Information

Do not open the brake system.
Do not loosen the brake hose from the brake calliper when loosening the brake calliper.
The core of the warning contact wire must not be left exposed! It does not matter if the insulation is worn.
If necessary, remove a little brake fluid from the reservoir by suction in order to prevent an overflow when the disc brake pads are pushed back.

1. Screw the two assembly aids (assembly pins) , instead of two wheel bolts, into the wheel hub before removing/fitting the wheel. During removal, first remove the three remaining wheel bolts and remove the wheel carefully without touching the brake discs.

2. Then (after removing the wheel), remove the two assembly aids (assembly pins) again.


Information

Do not open the brake system.
Do not loosen the brake hose from the brake calliper when loosening the brake calliper.
The core of the warning contact wire must not be left exposed! It does not matter if the insulation is worn.
If necessary, remove a little brake fluid from the reservoir by suction in order to prevent an overflow when the disc brake pads are pushed back.

3. Partially remove the brake calliper. Check the following while doing this:

Information

To gain better access for removal of the brake calliper, turn the steering fully either to the right or left.

3.1. Remove the holders -1, 2- for the brake hydraulic lines from the wheel bearing housing

Mounting for hydraulic lines (shown as an example, brake calliper removed)
3.2. Pull the brake pad wear indicator line out of the brake calliper.
3.3. Disconnect plug connection for speed sensor.
Information

Protect the paintwork on the brake calliper from damage using a suitable cloth.

4. Carefully press the brake pads back using water pump pliers. Remove a little brake fluid from the reservoir by suction if necessary in order to prevent an overflow!
5. Use removal/assembly aid for brake callipers assembly pin T10439.

Assembly pin on brake calliper
Information

Never use an impact bolter to loosen and tighten the brake calliper on the wheel carrier.

6. Remove top fastening screw on the brake calliper and insert assembly pin -top direction arrow- .

Fastening screws on brake calliper

7. Remove bottom fastening screw on the brake calliper and insert assembly pin -bottom direction arrow- .

Assembly pin for brake calliper fitted

8. Pull the brake calliper as far as required out of installation position until the brake calliper engages in the cut-outs on the assembly pins. Carefully guide the brake line and brake hose along as well!

Brake calliper tool fitted

9. Fit the brake piston between the brake pads on the brake calliper using piston resetting fixture (replaces P83) Nr.144, and press the pads back evenly -arrows- . Remove a little brake fluid from the reservoir by suction if necessary in order to prevent an overflow!

Pressing back brake pads

10. If you intend to re-use the brake pads, mark the relevant installation position. Carefully slide a commercially available screwdriver between the brake pad/brake calliper and lever the brake pad out by turning the screwdriver slightly. When doing this, make sure not to damage the dust boots on the brake pistons -arrows- .

11. Remove pad retaining springs.






Installing disc brake pads
Information

Never use an impact bolter to loosen and tighten the brake calliper on the wheel carrier.
Visually inspect the thread for the brake calliper and blow it out carefully if necessary using compressed air. Use goggles!
Replace screws.
Observe correct tightening torques → 4X00IN Tightening torques for the brake hydraulic system.

WARNING

Old mounting parts fitted on the brake calliper
Reduced braking effect
Risk of damage to the brake calliper
→ Fit new pad retaining springs
→ Fit new fastening screws


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.


Information

The back of the pad backing plates must not be greased.
Check disc brakes for wear.
Disc brakes must be clean and free of grease.
The core of the warning contact wire must not be left exposed! It does not matter if the insulation is worn.
If necessary, remove a little brake fluid from the reservoir by suction in order to prevent an overflow when the disc brake pads are pushed back.
Use new repair kit.


Installation is performed in reverse order.
1. Fit new pad retaining springs.
2. Place the brake pad onto the sealing surfaces of the pad retaining springs -arrows- .

Fitting brake pad
3. Press the brake pad into the brake calliper with slight pressure and slide it onto the pad retaining pins -arrows- .

Positioning brake pad
4. Fit the disc brake pad. -direction arrow-

Fitting brake pad

Subsequent work
1. Fit the brake calliper.
→ 473919 Removing and installing front brake calliper
2. Position disc brake pads by operating the brake several times.
3. Check the brake fluid level and correct it if necessary.
→ 470801 Checking brake fluid level
4. Fit the wheel. Use assembly aids (assembly pins)

Brake disc and calliper

Bedding in the brake pads
New brake pads require a bedding-in period of approx. 200 km (125 miles) 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!

How do you do the rears though? I've heard the electric parking brake complicates things.

No responses so does mean that nobody has tried this? My plan is to change pads thanks giving weekend. Hope to get some help before then.

Someone posted a step by step youtube that covered the whole process. It seemed pretty standard, with only one or two things you might want to know to make it easier. Let me look.

Let me know, all I found was for -10 and earlier which does not require you to remove the calipers. For the -11 + the caliper needs to come off the rotor. Either lift off or use the special tool listed above.

I've looked, and it seems to be earlier models. Sorry. The youtube I saw removed the calipers, but didn't require a special tool. Nothing beyond a hex-bit or something similar.

PS - I can't picture replacing pads without removing calipers.

For grins and because I have some credit left on my account I pulled up the rear brake procedure from PIWIS. I don't know what the person that told me the electronic parking brake complicates things was thinking. The procedure looks pretty much along the same lines as any brake job.

The tool pic looks like a long skinny 3 square. The caliper pic looks like you wouldn't need it.
