Right - here is the awaited thread on Hamilton’s brakes. It’s a long story, so be patient
I’ll start by saying, in F1 there are a few major components that make up braking systems. These are the discs, the callipers, the master cylinder as well as the pedal setup (stiffness, modulation).
Every F1 driver has a unique preferred setup regarding these components - and Hamilton’s was to use Brembo callipers (supplied to all teams) mixed with discs and the master cylinder from Carbone Industrie.
He used these at McLaren, and when he moved to Mercedes in 2013 he initially adopted a full Brembo system which he initially struggled with.
Why? This is where it gets interesting, and what you see in 2026 is quite similar.
CI discs are much larger and more powerful than Brembo discs. A lot more powerful, so much so that for 6 months Brembo were unable to replicate this on Hamilton’s 2013 Mercedes - that he made the switch to CI and the rest was history
2/4 An article from @SportmphMark
from early 2013 details this perfectly - and it’s the exact same story as 2026.
Essentially, it all comes down to working the front tyres. On the less powerful Brembo discs - Hamilton was unable to fire up the front tyres in his usual fashion. He said at Monaco:
“I have been struggling all weekend with the car. That last lap was the first time I felt like I had switched the front tyres on and even in that I had understeer. I haven’t had that since 2005. I don’t usually have a problem with confidence so really I am delighted to be second.”

Now, why does this combination work for Hamilton, but didn’t work for Rosberg for instance?
Fast-forward to Hungary 2015 - where Hamilton and Rosberg had a somewhat heated exchange in the press conference about the brakes.
Rosberg adopted Hamilton’s discs for various portions in an attempt to match Hamilton’s braking performance, to no avail.
Rosberg complained but Hamilton clapped back, saying “he felt perfectly fine on the brakes in Austria, just to let you know”.
In 2021, Rosberg detailed Hamilton’s technique of “feeding in the brake pedal” versus the traditional “stomp on the brakes and trail off” style he used.
When Rosberg used Hamilton’s CI brakes, the greater stopping power and stiffer pedal caused him to consistently lock the front tyres with no solution - and his old Brembo discs were not powerful enough to match Hamilton’s braking performance, so it was a lose-lose.
Now, onto 2026.
According to reports, Hamilton has pushed for his normal brakes to be used on his car since the day he arrived, but this process seemed to take nearly 18 months.
Essentially, Hamilton was left using Sainz’s brakes in 2025 and could only make minor adjustments due to the cost-cap and the focus on 2026 (according to Brembo themselves).
In terms of what the CI brakes are doing to the car, as mentioned above, the more powerful discs no doubt play a role in giving him those front tyre temps he is so sensitive about.
Here’s where it gets interesting - will it solve Leclerc’s issues?
Well, if the issues stem purely from the brake system themselves - he’ll swiftly have those issues eradicated at Barcelona.
However, Hamilton is the only driver to use CI discs on the current grid, and his choice comes from 20 years of feedback, honing in a style he developed when he was coming through the ranks.
Simply taking his brakes and getting them to work without the nuance of how they were developed is no easy task - and a dangerous rabbit hole t fall into if not careful.
Just for reference, McLaren had Akebono callipers at the time, not Brembo callipers.
I knew Akebono supplied something but couldn’t remember what exactly
