Replacement rear disc brake pads for the 2026-version KuKirin G2, G4 and G2 Ultra electric scooters.
Available in two braking compounds:
Black – Resin/Organic: Smooth, quiet braking with strong initial bite and good lever feel.
Gold – Full-Metal: Greater durability and heat resistance for demanding riding, wet conditions and repeated braking.
Each variant is supplied as a complete set with two brake pads and the matching retaining hardware shown in the product photographs.
Designed for the rear brake calliper fitted to:
KuKirin G2 – 2026 version
KuKirin G4 – 2026 version
KuKirin G2 Ultra – 2026 version
These pads do not fit every KuKirin G2, G4 or G2 Ultra brake calliper.
KuKirin has used several different brake-pad shapes and calliper configurations across different production years and versions. Before ordering, compare your existing pad with the photographs and confirm:
Rear brake position
Approximately 33.9 mm overall width
Approximately 40.3 mm overall height
Approximately 24.3 mm rectangular pad-body height
Position and shape of the retaining tab
Retaining-pin hole position
Friction-material slot
Spring or retaining-clip configuration
The two compounds share the same general outer pad shape, but their friction-material and spring configurations are different.
The resin pad provides smooth and quiet braking with strong initial bite and predictable modulation. It is a good all-round choice for commuting, casual riding and predominantly dry conditions.
Resin pads are generally gentler on the brake rotor but wear faster than full-metal pads, particularly in wet, muddy or high-temperature conditions.
Identifying features:
Black backing plate
Centre slot through the friction material
Small square opening on the reverse
V-shaped wire spring
Split retaining pin
The full-metal pad provides greater durability, heat resistance and sustained braking performance. It is better suited to heavier riders, repeated braking, steep descents and wet or dirty riding conditions.
Full-metal pads can produce more braking noise, require a longer bedding-in period and may cause greater rotor wear than resin pads.
Identifying features:
Gold backing plate
Continuous friction surface with no centre slot
Different wraparound leaf-spring configuration
Split retaining pin
The resin and full-metal retaining springs are different. Always install the matching hardware supplied with the selected pad set.
Overall width: approximately 33.90 mm
Overall height: approximately 40.33 mm
Rectangular pad-body height: approximately 24.34 mm
Small manufacturing tolerances may apply. Compare the shape and measurements with your existing brake pad before ordering.
One set contains:
Two brake pads in the selected compound
One matching spring or retaining clip
One split retaining pin
Suitable for servicing one rear brake calliper.
Brake installation is safety-critical. Keep the friction surfaces and brake rotor free from oil, grease and cleaning residue.
After installation, check that:
The pads move freely inside the calliper
The spring and retaining pin are correctly secured
The brake rotor is centred between the pads
The wheel rotates freely when the brake is released
The brake operates correctly before normal riding
Bed in the new pads with repeated controlled braking from a moderate speed. Avoid prolonged heavy braking until the pad surfaces have properly transferred and matched to the rotor.
