Zeekr 001 Big Brake Kit Upgrade / TTSPORT Evolution EB8
The factory brakes on a Zeekr 001 are tuned for daily comfort, not for hauling down a heavy EV from real speed with confidence. This build, done by Hangzhou Chedao, swaps the stock front setup for TTSPORT's new Evolution Series EB8 — a forged 8-piston caliper paired with a 405x34mm high-carbon heat-treated rotor — running behind the car's stock 21-inch wheels with no spacers.
The front axle gets the full EB8 package: caliper, rotor, custom bracket, pads, and stainless lines. Everything was engineered to clear the Zeekr 001's factory wheel without spacing the wheel out or altering the offset.

Why It Works
The EB8 is positioned by TTSPORT as a street-focused, high-performance caliper. Spreading clamping force across 8 pistons instead of the stock caliper's smaller count gives the pad more even contact against the rotor, which translates into stronger, more usable stopping power.
Each piston is a two-piece, internally vented design with an optimized seal setup, which helps the caliper hold up better under sustained heat and keeps bite consistent instead of fading as pads and fluid get hot. TTSPORT states this results in a more linear, refined pedal feel — especially noticeable at higher speeds, where braking stability and response matter most.
- Forged aluminum caliper body resists flex under hard, repeated braking compared to the factory unit
- 405x34mm high-carbon heat-treated rotor adds mass and heat capacity to resist fade on repeated stops
- Custom vehicle-specific bracket fits the EB8 caliper behind the Zeekr 001's stock 21-inch wheel with no spacers
- Built to handle high-intensity use and harsher operating conditions with a lower risk of failure or damage over time
