Forty tonnes.
Brought to rest.
ABS, EBS, calipers and discs for European trucks and trailers. Engineered for the long descent.

That is 9.9 megajoules in motion.
Every joule of it leaves through the brakes.
As heat.
ABS
Grip, held at the edge.
On packed snow a locked wheel stops steering. ARRESTA ABS watches every braked wheel through its own speed sensor. The moment one starts to lock, the modulator releases and reapplies pressure, many times a second, so the wheel keeps turning and the driver keeps the line.
- Layouts
- 4S/4M, 4S/3M, 6S/6M
- Sensing
- Inductive wheel-speed sensor per braked wheel
- Approval basis
- UN ECE R13
EBS
The pedal becomes a signal.
Electronic braking sets pressure axle by axle the instant the pedal moves, then tells the trailer to brake in step over the ISO 11992 link. Load sensing puts the work where the weight is.
- Brake signal transmitter
- Central module
- Rear axle modulator
- ISO 11992 trailer link
- Load sensing on air suspension
- Trailer EBS modulator
Tractor and trailer, braking as one.
No push from behind, no jack-knife from a trailer that brakes late.
Calipers
Clamp force from a single stroke.
The brake chamber pushes a lever, the lever drives two thrust plates, and the pads close on the disc. An automatic adjuster keeps the running clearance constant as the pads wear, so the pedal feels the same on the last kilometre of the pads as on the first.
The range
| Caliper | Wheel | Disc |
|---|---|---|
| AX-22 | 22.5″ | 430 mm |
| AX-19 | 19.5″ | 377 mm |
| AX-17 | 17.5″ | 330 mm |
Then the long descent.
Discs
Where the energy goes.
430 mm, internally ventilated. Radial vanes pump air through the disc every turn it makes.
High-carbon grey iron, chosen to hold its shape when it glows.
A separate hat lets the friction ring grow with the heat, without pulling the hub along.

Four systems, one stop. Every ARRESTA part is built for the moment nobody on the motorway ever notices.
