Zeekr 007 Big Brake Kit Upgrade / TTSPORT Classic 7640
This isn't the first Zeekr 007 or 007GT to come through the shop wearing a TTSPORT Classic 7640 up front — it's honestly hard to keep count anymore. The pattern behind every one of these builds is the same: a car with plenty of power and not quite enough brake to match it.
The Zeekr 007 was built around a straightforward idea: strong motor output, quick torque delivery, and a car meant for daily commuting, highway runs, and the occasional hard drive. That combination puts real demand on the brakes. The factory setup holds up fine around town, but on repeated high-speed stops, long downhill sections, or back-to-back hard braking, drivers start to notice fade and a pedal that goes soft. A car this quick needs a brake system built to the same standard as its powertrain.

Why It Works
The 007's problem was never straight-line speed — it was slowing a heavy, high-power EV down consistently and repeatedly. A few basic mechanics explain why this kit addresses that:
- A forged six-piston fixed caliper with a two-piece aluminum body flexes less under load than a stock sliding caliper, which keeps pad pressure even and the pedal consistent instead of going long and soft.
- The 380mm rotor adds mass and swept area over the factory disc, giving the system more thermal capacity to absorb heat on long downhills or repeated hard stops before fade sets in.
- The vehicle-specific bracket geometry is sized to clear the Zeekr 007's factory 19-inch wheels, so no spacer is needed and offset and track width stay unchanged.
Drivers who've done the swap describe a light initial bite, a linear mid-pedal build, and strong confidence at full travel — no nose-dive around town, no anxious moments on a highway panic stop, and no fade after repeated use. It's not track-only stiffness; it's a pedal tuned for daily driving that also holds up when the car is pushed.
