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
