Exact Compatibility & Fitment Notes

TONGLI rectangular hollow brake pads function specifically within hydraulic disc brake systems. Verified model compatibility includes the Kugoo G-booster and KuKirin G4 electric scooter frames, alongside standard mountain bike hydraulic calipers. Physical dimensions measure 30mm by 30mm with a thickness of 4.5mm. Users must verify caliper clearance before purchase to ensure proper rotor alignment. Replacement becomes necessary when the pad friction material thickness drops below 1mm or when braking performance decreases due to surface glazing or contamination. Consistent monitoring prevents rotor damage caused by metal-to-metal contact during deceleration.

Material Durability & Technical Features

High-density, full-metallic lining construction facilitates heat dissipation during frequent braking cycles. Metallic compounds offer increased friction coefficients compared to resin-based alternatives, particularly in wet or steep terrain. Rectangular hollow geometry promotes airflow, which reduces thermal buildup within the caliper housing. Each unit weighs 0.04kg, contributing minimal mass to the unsprung weight of the braking system. Installation requires removing the caliper pin, sliding out worn components, and resetting the hydraulic pistons to accommodate the thicker profile of the new pads. Proper bed-in procedures involve controlled braking on flat surfaces to align the pad surface with the existing rotor track. Mechanical integrity stays stable under heavy loads, provided the braking surfaces remain free of oil and debris.
