Honda Accord Big Brake Kit Upgrade / TTSPORT Evolution ES6
The Honda Accord has built its reputation on being reliable, comfortable, and easy to live with — not on outright braking performance. For an owner who drives hard on mountain roads, that shortfall showed up at the worst possible moment: a hard emergency stop where the factory brakes felt slow to respond and confidence dropped fast. The fix was a TTSPORT Evolution ES6 big brake kit up front, paired with a larger rear rotor at the stock caliper location.
The front axle picks up a TTSPORT ES6 six-piston caliper matched to a 380mm high-carbon rotor, spreading clamping force more evenly across a larger contact patch. At the rear, a 325mm high-carbon rotor slots into the factory caliper position, tightening up the front-to-rear brake balance without changing the rear hardware setup.
Vehicle & Kit Specs
The full kit is built around a vehicle-specific bracket so the ES6 caliper lines up correctly with the factory hub — no spacers, no guesswork. Everything needed for the install is included, down to the fasteners and fluid.

Why It Works
Forged rigidity, even clamping force
The ES6 is a mid-size six-piston caliper built from forged aluminum in two pieces, with an asymmetric, weight-reduced internal design that still keeps piston pressure distributed evenly across the pad. Cross-caliper reinforcement ribs add stiffness — TTSPORT cites a 20–30% strength gain over a conventional layout — which means less flex under hard braking and a more linear, progressive pedal.
- Two-piece heat-insulated pistons with dust boots and high-temp seals handle sustained heat and hold clamping consistency, and are also compatible with carbon-ceramic rotors.
- Stepping the front rotor up to 380mm and the rear to 325mm adds swept area and thermal mass on both axles, so the whole system shares the load more evenly instead of leaning on the front alone.
- A vehicle-specific bracket keeps the ES6 caliper positioned correctly behind the factory 19-inch wheel — no spacers needed to clear the spokes.
