As Red Bull’s RB19 is prepared for action we’re treated to a view of the front brake assembly at different stages of the build, with the brake caliper fairing installed on the left-hand side of the car, while it’s naked on the right.
Note that the fairing doesn’t have the central window closed at this stage either, which is an option should the team want to alter the way heat moves between the various nests of the brake drum.
The small cooling tube fins can also be seen on the exposed caliper, along with the larger central vents that the team has employed for 2023 to allow heat rejected by the brake disc passage through the caliper.

The Alfa Romeo C43’s front brake assembly, without the main drum cover in place, shows us how differently the arrangement is configured, with the caliper mounted towards the rear, which in-turn results in the brake disc fairing wrapping around the front of the disc.
Note that Alfa Romeo has extended the length of the nose for Australia, with the tip now reaching forward to the leading edge of the mainplane, rather than sitting back behind it on the second element. As a consequence, changes have also been made to the front wing to accommodate the alteration.

Williams is another team to sport the tube fin design on their front caliper, albeit only present on the front and rear of the caliper, with horizontal fins present in the central section.

The FW45’s front brake assembly, now with the fairings in place that wrap around the caliper and disc, is very similar to the design used by Red Bull in 2022.

Ferrari’s caliper is fed cool air by two channels, one either side of the fairing, while ports in the central section of the caliper and fairing allow heat rejected by the drill holes in the disc a passage to move through the assembly.
The SF-23 also has a disc fairing this year, not shown in this image, although that does give us a glimpse of the X-shaped drill pattern in the disc.
