This bolt is used on various Porsche brake caliper applications, depending on model and axle position.
What This Part Does / Functions
• Secures the brake caliper to the hub carrier / upright
• Maintains correct caliper alignment over the brake disc
• Helps ensure consistent braking performance
• Supports safe operation of the hydraulic brake system
• Provides correct OE Porsche thread, length and strength specification
• Replaces worn, damaged, corroded or previously removed caliper bolts
• Helps prevent caliper movement caused by incorrect or worn hardware
• Maintains factory Porsche brake system fitment and quality.
Why Replace This Part?
Brake caliper mounting bolts are safety-critical fasteners. They are exposed to high braking loads, heat cycles, road debris, corrosion and repeated service removal. If a bolt is stretched, damaged, corroded, rounded or incorrectly reused, it may not clamp the caliper securely. Replacing caliper bolts with OE Genuine Porsche hardware helps ensure the brake caliper is fastened correctly using the proper factory specification.
When to Replace This Part
• When removing or replacing a brake caliper
• During brake caliper refurbishment or upgrade work
• If the original bolt is corroded, seized, rounded or damaged
• If the bolt threads are worn or contaminated
• During front or rear brake overhaul
• If the caliper mounting hardware is missing or incorrect
Where It Fits on the Car
This bolt fits at the brake caliper mounting point, securing the caliper to the suspension upright / hub carrier. Depending on the vehicle application, it may be used on the front calipers, rear calipers, or both.

Whenever brake calipers are removed for servicing, pad replacement, disc replacement or caliper refurbishment, it is good practice to inspect the mounting bolts for wear, corrosion or thread damage. Replacing worn or damaged fasteners helps maintain correct clamping force and supports safe, reliable brake operation.
Manufactured from high-grade steel with the correct dimensions and thread specification, this mounting bolt provides a secure and dependable fit for a wide range of modern Porsche models.
What Does the Brake Caliper Mounting Bolt Do?
The brake caliper mounting bolt fastens the brake caliper securely to the hub carrier or suspension upright. It is responsible for maintaining the precise alignment of the caliper while resisting the significant braking forces generated under heavy deceleration.
Why Replace the Brake Caliper Mounting Bolt?
Brake mounting bolts experience repeated heat cycles,
vibration and extremely high clamping loads. Over time they may suffer from:
- Corroded or damaged threads
- Wear from repeated removal and installation
- Loss of protective coating
- Incorrect torque from previous servicing
- Stretch or fatigue after extended use
Replacing the bolt during brake maintenance helps ensure the caliper remains securely mounted.
Common Symptoms of a Worn or Damaged Mounting Bolt
- Damaged or stripped threads
- Corrosion on the bolt shank or head
- Difficulty achieving correct torque
- Caliper movement due to incorrect fastening
- Fastener showing signs of previous over-tightening
Features
- Direct replacement brake caliper mounting bolt
- High-strength steel construction
- Precision manufactured for accurate fitment
- Designed for demanding braking loads
- Ideal during brake disc, pad or caliper replacement
- Helps maintain correct brake caliper alignment
- Suitable for road and performance applications
