Zeekr 001 Big Brake Kit Upgrade / TTSPORT Classic 8703S
Zeekr's 001 is a heavy, quick electric liftback, and factory brake hardware on cars like this is built to a price and a weight target — not to a repeated hard-stop target. This case documents a Zeekr 001 fitted with a TTSPORT TT8703S big brake kit, a straightforward OEM+ upgrade aimed at giving the factory setup more capability without reinventing the wheel.
TTSPORT builds each kit — calipers, rotors, pads, and fluid — as a matched set rather than mixing components from different sources. The goal on a car like the 001 is the same as on any performance platform: firmer pedal feel and more margin before the brakes start to fade under repeated hard use.

Why It Works
The basic mechanism behind any big brake kit is the same, and it's worth spelling out rather than just taking on faith. A forged caliper is stiffer than a factory sliding caliper, so less of the driver's pedal pressure gets lost to caliper flex and more of it goes straight into clamping force on the pads. A larger, heavier rotor has more mass to soak up heat during hard braking, which delays the point where the pads and fluid start to overheat and the pedal goes soft — the classic symptom of brake fade.
- Forged caliper construction reduces flex, so pedal input translates more directly into clamping force.
- Matched rotor and pad hardware is sized to work together for more predictable bite and wear.
- A complete kit — caliper, rotor, pads, fluid — avoids the guesswork of mixing components from different sources.
Fitment Notes
TTSPORT's general design approach for platform-specific kits like the TT8703S is to work from the factory hub and mounting points, using vehicle-specific hardware rather than generic adapters. That's the philosophy behind this installation on the Zeekr 001: a kit built for this particular platform, not a universal part forced to fit.
As with any brake upgrade, wheel clearance should always be confirmed for the specific wheel and offset combination on the car before ordering.
