Freelander Brake Discs

wrote:


Drilled/Grooved discs offer no increase in stopping performance, but
they do allow for greater use of the brakes, as the holes/grooves keep
the disc cooler and help to stop brake fade. Vented discs usually have
adequate cooling for normal useage anway.

Also, under extreme conditions drilled discs are weaker when subjected to
severe usage - probably not an issue on a freeblander but something to be
aware of nonetheless. Discs that are grooved and dimpled (drilled but not
right through) are said to be some of the best in terms of pad gassing and
debris removal but still retaining strength. On a road vehicle, I'd go with
standard or grooved only.
