•  If caliper mounting hardware is missing or incorrect
•  During front brake disc, pad or caliper service where replacement is recommended

Where It Fits on the Car
This bolt fits at the front brake caliper mounting point. It secures the front caliper to the suspension upright / hub carrier. Correct torque specification and Porsche workshop procedure must always be followed during installation.

Brake caliper mounting hardware is safety-critical and should be fitted by a competent technician.

Brake Disc Mounting Screws. M6 x 16. (for vehicles with 5mm spacers/Factory option XRP)
2 x Brake disc screws are required per disc/5mm spacer.

Brake disc retaining screw is an extended length fixing screw designed specifically for Porsche vehicles fitted with factory 5mm wheel spacers. It secures the brake disc (rotor) to the wheel hub, ensuring correct disc positioning during wheel installation and brake servicing. On vehicles equipped with factory spacers, standard-length disc screws are too short to achieve proper thread engagement. This longer version compensates for the additional spacer thickness, allowing the brake disc to seat correctly against the hub and remain accurately aligned until the wheel bolts are installed. Manufactured to Porsche factory dimensions and thread specification, this screw provides correct fitment, corrosion resistance, and reliable retention during service and assembly. It is a critical but often overlooked component when working on cars with OEM wheel spacers.

Fits:
Porsche 996
Porsche 997.1
Porsche 997.2
Porsche 991.1
Porsche 991.2
Porsche Boxster 986
Porsche Boxster 987.1
Porsche Boxster 987.2
Porsche Cayman 987C.1
Porsche Cayman 987C.2

Porsche Panamera 970

Why Replacement Matters: 
Using a standard-length brake disc screw on a spacer-equipped hub can result in insufficient thread engagement, leading to poor disc retention or stripped threads. Replacing missing or incorrect screws with the proper extended version ensures correct assembly, avoids hub damage, and maintains factory-correct brake installation.

This high-strength fixing is engineered to withstand the extreme forces and temperatures generated during braking. Whether replacing damaged hardware, rebuilding the braking system or installing new brake discs or calipers, using Genuine Porsche mounting bolts helps maintain the safety, reliability and performance of your vehicle.

What Does the Brake Caliper Mounting Bolt Do?

The brake caliper mounting bolt is a critical safety component within the braking system.

Its primary functions include:

• Securing the brake caliper to the suspension upright.
• Maintaining precise caliper alignment with the brake disc.
• Withstanding the high braking forces generated during normal and performance driving.
• Preventing caliper movement under heavy braking.
• Helping ensure even brake pad contact and consistent braking performance.

Correct caliper mounting is essential for safe, predictable braking and long-term brake component life.

Why Should Brake Caliper Mounting Bolts Be Replaced?

Brake caliper bolts are subjected to repeated high loads and temperature cycles throughout their service life.

Replacement is recommended because:

• Threads can become stretched or damaged during removal.
• Corrosion may reduce the integrity of the bolt.
• Repeated tightening can affect clamping performance.
• Previous incorrect torque settings may compromise the fixing.
• Brake system upgrades often require new mounting hardware.
• Genuine replacement bolts ensure the correct strength and specification.

Using new genuine hardware helps maintain the correct clamping force specified by Porsche.

When Should They Be Replaced?

Replacement is recommended when:

• Replacing or rebuilding brake calipers.
• Installing new brake discs.
• Performing major brake servicing.
• The original bolt shows signs of corrosion or damage.
• Threads are worn or damaged.
• Carrying out a complete brake system overhaul.
• Following Porsche workshop recommendations where new hardware is specified.

Replacing brake hardware during brake servicing is an important part of maintaining braking safety and reliability.
