The TTSPORT 7642TK is a Direct-Mount Series front big brake kit engineered for 2021-2026 GWM Tank 300 builds. It pairs a 6-piston forged aluminum caliper with application-correct one-piece high-carbon rotors — Ø335 mm × 32 mm for ICE models and Ø345 mm × 32 mm for Hybrid models — plus stainless braided lines and vehicle-specific fittings for loaded trucks, larger tires, and repeated heavy braking.
Larger off-road tires, steel bumpers, drawers, recovery gear, and long descents all push more energy into the front axle than the stock setup is sized for. The 7642TK adds piston area, swept area, and rotor mass exactly where the Tank 300 needs it — the front — so pedal feel stays firm and fade resistance improves on repeated heavy stops.
Vehicle-specific direct-mount geometry and brake-line fittings for the GWM Tank 300 front axle — no universal-bracket guesswork.
Two-piece forged aluminum body with 34 mm × 2 and 38 mm × 4 pistons, 63.5 cm² total piston area per caliper for stronger, more even clamp.
Tank 300 ICE uses Ø335 mm × 32 mm front rotors, while Tank 300 Hybrid uses Ø345 mm × 32 mm front rotors.
One-piece heat-insulated pistons with dust boots help manage heat and contamination during repeated braking events.
PTFE inner liner, SUS304 stainless braid, and PVC protective outer sheath help maintain a firmer pedal under load.
Built for loaded Tank 300 builds, larger tire packages, towing, trail use, and repeated heavy braking events.

For 2021-2026 GWM Tank 300, the correct 7642TK rotor specification is Ø335 mm × 32 mm for ICE models and Ø345 mm × 32 mm for Hybrid models. Confirm 17 in or larger wheels and 94 mm minimum spoke clearance before ordering.
2 × 7642TK 6-piston forged aluminum front calipers, left/right specific.
Brake pads for both front calipers, rated 0–600 °C and intended for iron / steel rotors.
2 × one-piece internally vented high-carbon front rotors, left/right specific. ICE uses Ø335 mm × 32 mm; Hybrid uses Ø345 mm × 32 mm.
2 × three-layer stainless-steel braided brake lines with PTFE inner liner, SUS304 braid, PVC protective outer sheath, and vehicle-specific fittings.
Vehicle-specific direct-mount hardware for GWM Tank 300 front-axle installation.
Direct-Mount Series uses one-piece rotors and direct-mount calipers. Rotor Hats and Caliper Brackets are not included because they are not used on this 7642TK application.
7642TK requires 17 in or larger wheels with at least 94 mm of spoke clearance. Wheel diameter alone is not enough; spoke shape, offset, and inner barrel profile must be checked before ordering.
17 in or larger wheels are required.
Minimum spoke clearance: 94 mm. Check spoke shape, offset, and inner barrel profile before ordering.
Application: 2021-2026 GWM Tank 300, front axle. ICE uses Ø335 mm × 32 mm; Hybrid uses Ø345 mm × 32 mm.
