Here Are The Compact, Ultra High-Tech Brakes F1 Cars Are Using In 2018
The 2018 breed of F1 cars is set to be the fastest ever as the combination of constantly-evolving aerodynamics and softer, grippier Pirelli tyres should be good for an extra second or two per lap over last year’s machinery.
The brakes are an often forgotten aspect of F1 cars, but the level of development that goes into them is no less than you’d see for an engine or a front wing. Brembo supplies most of the grid and with the extra speed (and the extra weight caused by the Halo), the Italian manufacturer hasn’t skimped on the details of this season’s braking equipment.
To cope with the extra stresses caused by the stickier tyres, the carbon discs have gained an extra 100 ventilation channels to help cool them down from over 1000 degrees centigrade. There are three types of disc depending on the circuit, ambient temperature and race strategy, ranging from 900 holes to 1200, with a massive 1500 on the beefiest set. Front discs will generally be 32mm thick, with the rears at 28mm.
They’re incredibly light, too - at little more than a kilo each, they weigh six times less than the carbon ceramic discs you might find on sports car, and 12 times less than regular steel discs.
There’s no holding back when it comes to the calipers, either, which themselves can reach 200 degrees centigrade. Despite the demands, keeping the weight down is key, so Brembo has managed to make them lighter and stiffer to maximise the effectiveness of the brake-by-wire systems.
This is especially evident with the rear brakes, which only run four-piston calipers (as opposed to the six-piston ones at the front) because the resistance generated by the energy recovery systems of the hybrid power units aids with the stopping power.
Brembo works with each team to produce bespoke discs, depending on whether there’s a preference for lighter, but less stiff discs, or ones with a stiffer construction at the cost of increased weight. Where thousandths of a second can make an enormous difference, the driver having confidence in the feel of their brakes is absolutely vital.
A Formula 1 caliper is expected to last for at least 10,000km, with teams ordering a dozen or so sets to get them through the year. Discs need to be changed a little more frequently - generally, a team will need between 140 to 240 per season, and upwards of 480 pads.

These brakes probably break the bank
“Brake” puns? It’s time to stop.
The door is to the right please exit 😂
Still won’t work for Moanjean
But experiencing this technology is certainly a heart stopping experience
I guess we need Nitrogen filled tyres next and then we are good!
They already use Nitrogen filled tires.
When can I put these on my civic?
They probably cost more than a Civic.
When is the bigger wheels coming? I mean F1 is the only series that i can think of that still uses 15 and 13/4(?) inch wheels.
Bigger wheels means space for bigger brakes means later braking right? So why F1 don’t switch to 18’ or above? (idk I’m not a racing driver)
Bigger wheels were tested a few years ago, and they were much faster than the smaller ones. That was only an experiment, though
Bigger rim = less rubber = less grip
It would require a massive redesign. Bigger wheels means less tyre, so they’d have to redesign their whole suspension systems as they use the tyre side wall as part of the suspension set up.
Small rims and small brakes reduce the unsprung mass, but I’m fairly sure that the better braking performance and - more importantly - the less brake fading you get from installing larger brakes would outweigh the mass disadvantage. And since just about everything on these cars is made of carbon fibre, I would even doubt that the unsprung mass will be increased by too much.
F1 cars are slowed down by the rules in many aspects. Ferrari and Mercedes could make their cars five seconds faster around the lap without too much effort if they had free rein. But that’s what the F1 is about - building the fastest possible car that’s still conform with the rules. If everyone had free rein, they’d all be driving cars based around the concept of the Brabham BT46B.
So that’s why HAAS was doing well. I mean, at until the wheels “broke” loose.
I know my way to the door, thank you very much.
Will it fit my Honda ?
Still gets defeated by a plastic sandwich bag. Those who saw the Australian Grand Prix and Sirotkin’s retirement know what I mean
