How It Works

Mill Out The Damage.
Insert A New Segment.

Brake discs can get worn, damaged - or break outright. Our mobile uptower machine mills away the damaged section and fits a new one, completing the repair in place.

How the repair works

The machine is mounted at the brake disc, mills away the old damaged "pocket", and a new segment is inserted - completing the job without removing the disc from the turbine.

Why repair uptower

  • The brake disc is repaired in place - no component exchange
  • Functionality of the brake system is restored
  • Further damage development is stopped early
Technical Specifications
Equipment Mobile uptower milling machine
Method Damaged pocket milled out, new segment inserted
Repair location Uptower, in place
Repaired Uptower The disc stays on the turbine - the damaged section is milled out and replaced in place.
Function Restored A new segment restores the brake system to working condition.
Damage Stopped Early repair stops further damage development in the disc.
No Exchange Repairing the damaged section avoids exchanging the component.

FAQ

Frequently asked questions

Can a damaged brake disc be repaired uptower?

Yes. A mobile machine is mounted at the disc, mills away the old damaged pocket, and a new segment is inserted - completing the repair in place.

What brake disc damage can be repaired?

Discs that are worn, damaged or even broken can be addressed by milling out the damaged section and fitting a new one.
