Audi A3 Big Brake Kit Upgrade / TTSPORT Classic 5410
This Audi A3 owner had the same complaint we hear a lot: the first quarter of pedal travel felt empty. Fine at city speeds, but not something you want to trust at highway speed. The fix wasn't a fluid flush or new pads — it was a front big brake kit swap to the TTSPORT 5410.
Audi brought its luxury-brand build quality down to a more accessible price point in China back in 2014, and the A3 has been a popular entry point ever since. But like a lot of factory setups tuned for comfort and cost, the stock brake system leaves a soft, long pedal that doesn't inspire confidence once you're moving fast. That's the gap TTSPORT's 5410 kit was recommended to close.
Vehicle & Kit Specs
| Item | Specification |
|---|---|
| Vehicle | Audi A3, fitted with 18-inch wheels |
| Front caliper | TTSPORT 5410 forged four-piston caliper, 6082 aluminum alloy, ~3.18 kg per caliper, dust boots for street use |
| Front rotor | 355 x 32mm high-carbon, heat-treated, directional-vented, drilled rotor with high-temp coating |
| Lines | TTSPORT stainless steel brake lines |
The install swaps in a forged caliper with a large four-piston layout and a hand-finished exterior that's easy to pick out behind the wheel. The bigger 355x32mm rotor gives the system more mass and surface area to work with than the factory disc.
Why It Works
- Forged 6082 aluminum alloy construction keeps the caliper light (about 3.18 kg) to cut unsprung weight while staying rigid under clamping load — that rigidity is what removes the sponginess from the pedal.
- The 355x32mm directional-vented, drilled, heat-treated rotor gives the system more thermal mass, which helps it shed heat and resist fade under repeated hard stops.
- Dust boots on the caliper are a street-focused touch, keeping grit out of the piston bores for consistent, linear braking over time — not just on a track day.
- Fitment was confirmed behind this Audi A3's factory 18-inch wheels.
