Zeekr 001 Big Brake Kit Upgrade / TTSPORT Evolution ES6
16 Jul 2026
Heavy EVs like the Zeekr 001 put real load on their brakes. Curb weight is high, and even with regenerative braking handling most day-to-day slowing, the friction brakes still have to do the work in hard, repeated stops. That's exactly the kind of use where a factory floating caliper can start to feel soft or inconsistent under the pedal. This case swaps the front axle to a TTSPORT ES6 big brake kit from the Evolution Series.

Why It Works
- The ES6's two-piece forged aluminum body resists flex under hard, repeated braking, so pedal feel stays firm rather than going soft or spongy.
- Six pistons per caliper (27mm, 32mm, and 38mm pairs) add up to roughly 50.2 cm² of combined piston area, spreading clamping force evenly across the pad for a stronger, more linear bite.
- A radial-mount design paired with a vehicle-specific bracket keeps the caliper centered on the rotor with no spacers needed.
- Rated for 18-inch wheels and larger with a 99mm minimum spoke clearance, the kit tucks behind the Zeekr 001's factory wheels.

Frequently Asked Questions
Does the TTSPORT ES6 big brake kit fit under the Zeekr 001's factory wheels?
Yes. The ES6 caliper is designed for wheels 18 inches or larger with a minimum spoke clearance of 99 mm, so it clears the Zeekr 001's factory wheels without spacers.
What type of caliper does the ES6 kit use?
The ES6 is a two-piece forged aluminum caliper with six pistons per side (27mm x2, 32mm x2, 38mm x2), giving roughly 50.2 cm² of total piston area for even pad contact.
What rotor size does the ES6 caliper work with?
TTSPORT recommends the ES6 caliper with rotors in the Ø355-380mm x 32mm range, paired with a vehicle-specific bracket for the Zeekr 001.
