Things are Heating Up
High temperatures are an inevitable consequence of heavy braking – especially on track. When braking systems are pushed hard, excessive heat can quickly become the limiting factor, leading to issues ranging from brake fade to brake fluid boil.
If your system isn’t correctly specified, a single hard session can be enough to end your day early.
Where the Heat Comes From
The primary function of a brake is simple:
to convert kinetic energy into thermal energy.
The challenge isn’t generating heat – it’s controlling where that heat goes.
Different components within a braking system absorb and transfer heat in very different ways, and each has its own failure mode when temperatures climb too high.
Brake Fluid Boil: The One You Really Don’t Want
One of the most critical – and dangerous – failure modes is brake fluid boil.
This occurs when excessive heat is conducted from the pad–disc interface, through the backing plate, and into the caliper. If the brake fluid reaches its boiling point – typically 190–270°C for DOT 5.1, depending on age and condition – braking force can drop off almost instantly.
Because calipers are heavy components with limited airflow, heat tends to linger. In many cases, the only solution is a complete cooldown before driving can safely resume.
Brake Fade: More Common, More Manageable
Brake fade, while frustrating, is generally less severe.
Fade occurs when excessive temperatures at the pad–disc interface cause the friction compound to outgas. These gases form a thin boundary layer that slightly lifts the pad away from the disc, reducing braking effectiveness.
Most performance brake pads are scorch-treated or bedded-in to remove these gases before use, significantly reducing fade during operation. When fade does occur, it can usually be managed with cooling laps and airflow.
Keeping Heat Where It Belongs
So how does Tribol Braking address these challenges?
The key is stopping heat from travelling where it causes the most harm.
Tribol’s patented composite backplate acts as a highly effective thermal barrier, dramatically reducing heat transfer into the caliper. Our composite material is:
- Over 100× less thermally conductive than mild steel
- More than 10× less conductive than Grade 5 titanium
This keeps heat concentrated at the disc – where it can be dissipated efficiently – rather than soaking into the caliper and brake fluid.
A Compound Designed to Match
Thermal management doesn’t stop at the backplate.
Tribol brake pads are paired with a high-performance friction compound engineered for:
- Low fade
- High thermal stability
- Consistent friction across repeated hard stops
Every pad is scorch-treated and track-ready, delivering predictable braking performance from the first session to the last lap.
Why It Matters on Track
Controlling heat isn’t about comfort – it’s about confidence.
Lower caliper temperatures, stable friction, and resistance to fade allow drivers to:
- Brake harder, for longer
- Maintain pedal feel deep into a session
- Push without worrying about sudden performance loss
That’s where time is found – and days aren’t cut short.
