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
