ER or LR Brakes - Embraer Legacy E35L
 

Hello PPRuNers,

Does anybody know the difference between "ER or LR Brakes" (ref. Embraer Legacy AFM, Supplement 9, Embraer Takeoff Analysis Software ETOASECJ, pp S9-3 f)?

Any hint would be greatly appreciated.

On a further note, it appears the distinction refers to different brakes by BF Goodrich. The performance software, however, seems to compute the same distances and masses regardless of which brakes are being selected.
