How do Chinese EV brakes work and do they wear like conventional cars?
Brake life is one of the most under-appreciated cost advantages of EVs. Here's what to expect and how to manage it.
Regen does most of the work
In one-pedal driving mode (available on all major Chinese EVs), lifting off the accelerator triggers up to ~0.25 g of deceleration via motor regen. Friction brakes engage only for stronger stops or emergency AEB.
Result: 60–80% less friction-brake wear than an equivalent ICE.
The corrosion problem
Discs that rarely engage develop surface rust — especially in salt-belt climates. This is cosmetic in the short term but can cause noise and uneven pad wear if left for months.
Fix: once a week, do 2–3 hard brake applications from ~80 km/h down to 20 km/h. This wipes the disc face clean.
When to expect replacement
Pads: front 90,000–120,000 km; rear 100,000–130,000 km.
Discs: often outlast pads with 2 pad changes — 180,000+ km possible.
Cost at replacement: pads £120–200, discs £200–400 (per axle).
