The TTSPORT 7640TK is a Direct-Mount Series front big brake kit engineered for 2024-2026 GWM Cannon Alpha / Poer Sahar / P500 applications. It pairs a two-piece forged aluminum 6-piston caliper with Ø335 mm × 32 mm internally vented one-piece high-carbon cast-iron rotors, stainless-steel braided brake lines, and vehicle-specific fittings.
This kit is built for loaded pickup use, towing, heavier wheels and tires, overland weight, rough roads, and long downhill braking where stronger front-axle control and repeatable pedal feel are needed.
Why GWM Cannon Alpha / Poer Sahar / P500 Builders Choose the 7640TK
The Cannon Alpha, Poer Sahar, and P500 names are used across different markets for the same GWM pickup platform family. The 7640TK keeps the brake upgrade vehicle-specific by using direct-mount front caliper geometry, matched brake-line fittings, and a fixed Ø335 mm × 32 mm rotor specification.
6-Piston Forged Caliper
Two-piece forged aluminum caliper with 27 mm × 2 / 32 mm × 2 / 38 mm × 2 staggered pistons.
50.2 cm² Piston Area
50.2 cm² total piston area per caliper helps deliver controlled front-axle clamp force.
Ø335 mm × 32 mm One-Piece Rotor
Heat-treated high-carbon cast-iron rotor, internally vented, fixed, directional left/right specific, with curved slot / Grain Slot face pattern.
99 mm Spoke Clearance
Recommended for 17 in or larger wheels with at least 99 mm minimum spoke clearance.
Three-Layer Brake Lines
PTFE inner liner, SUS304 stainless-steel braid, and PVC protective outer sheath help reduce hose expansion.

Quality hide
Size: 2' x 3' (Oblong)
I've purchased 5 hides from different offerings on this platform. I keep coming back to these for my needs due to the quality and price. I also prefer the natural state these are in, compared to the dyed versions offered by others. Highly recommend by me someone who actually uses them for home bedding and camping bedroll purposes.
