Geely Boyue Big Brake Kit Upgrade / TTSPORT Classic 8611
This Geely Boyue came in with the factory single-piston front brakes still on it, and the owner wasn't happy with the soft, vague pedal that comes with that setup. The fix: TTSPORT's newly released TT8611 forged six-piston caliper, paired with a 355x28mm high-carbon heat-treated curved-slot rotor and stainless steel lines — an OEM+ swap built to bolt on behind the stock 18-inch wheels.
The single-piston OEM calipers on this SUV clamp fine for daily commuting, but they run out of authority quickly once the pads and fluid heat up. TTSPORT's answer was to replace the whole front corner — caliper, rotor, and lines — rather than just swap pads, which is the only way to actually change how the pedal feels and how the brakes hold up under repeated hard stops.

Why It Works
Each TT8611 caliper weighs just 2.10 kg. That ultra-light, ultra-thin build trims unsprung weight at the corner, which helps the suspension react faster over rough pavement. Inside, three opposed pistons of different diameters sit on each side rather than matched pairs — that staggered layout keeps pad pressure more even across the pad face, so the caliper delivers strong clamping force without giving up the linear, predictable feel a street car needs.
- Forged aluminum caliper body sheds heat better than the cast-iron OEM single-piston caliper it replaces.
- The 355mm rotor is noticeably larger than the factory disc, increasing pad contact area for a stronger, more consistent bite.
- TTSPORT states the TT8611 is currently the only six-piston caliper that clears 17-inch wheels with no spacers, so it sits comfortably behind this Boyue's 18-inch wheels.
