Volkswagen Bora Big Brake Kit Upgrade / TTSPORT Classic 9040
The Volkswagen Bora was FAW-Volkswagen's first fully in-house designed model, and it's stuck around as a favorite for its balanced looks and solid German build quality. This case looks at a Bora owner who wanted sharper, more confident braking to match the car's spirited driving character — the fix was a TTSPORT TT9040 big brake kit running behind the stock 18-inch wheels.
The upgrade swaps the factory single-piston setup for a forged, split six-piston caliper and a larger 355x32mm rotor — a straightforward hardware change that reworks how the whole braking system responds under the pedal.

Why It Works
The TT9040 caliper is a split (two-piece) forged design with six pistons arranged in an opposed layout, and the pistons aren't all the same size. That staggered piston setup helps clamping force build more evenly across the pad as pedal pressure increases, so the response feels linear rather than grabby or dead at the top of the stroke.
- Larger 355x32mm rotor mass adds heat capacity versus the factory disc, which helps resist fade under repeated hard stops.
- Slotted rotor face keeps the pad surface cleaner and helps vent gas and debris during heavy braking, on top of looking sharp behind an open wheel.
- Fits behind the Bora's 18-inch wheels with the kit's included hardware — no spacers needed for this fitment.
After the swap, the owner reported a noticeably firmer pedal — real bite under initial pressure and the kind of "press it, it stops" confidence that's hard to get out of a stock single-piston setup.
