Not true. Brakes need time to dump heat. With repeated hard braking it's not too hard to overwhelm the brakes on most cars.

- tempestn 3y agoBut the scenario we're talking about here isn't repeated hard braking.
- fsckboy 3y agobrakes heat up, and the hotter they get, the faster they dissipate heat. nobody here has taken that non-linearity into account.
- tempestn 3y agoThe relationship between temperature and friction varies for different brake pads. Of course everything dissipates heat faster the hotter it is, but only racing pads actually tend to gain friction with heat (up to a point). But again, it doesn't matter, because road cars are traction limited in braking.
