In a few sentences

In brief

The construction must be compared to the rest of the braking system.

Useful to know

HELLA offers apparatus with a different number of pistons and variants with or without a clamp. These differences show why a common photograph is not enough to choose a substitute. [1]

More pistons do not automatically give an estimate of the braking distance of the entire vehicle. Dimensions, controls and other components participate together. Upon purchase, specify whether all the necessary knot is offered and for which side it is intended. Compare exact numbers and applications instead of accepting visual similarity as proof of compatibility.
