Toyota Alphard/Vellfire Big Brake Kit Upgrade / TTSPORT Evolution ES6
A lot of Alphard and Vellfire owners want more braking feel and power, but they don't want to run flanges, spacers, or bigger wheels to get it. That's the exact problem TTSPORT built the Evolution ES6 kit around: a vehicle-specific, narrowed six-piston caliper that clears the factory 18-inch wheel with nothing added in between.
The stock brake on these minivans is tuned for comfort, not repeated hard stops — heavy curb weight plus a soft factory caliper adds up to a mushy pedal and fade under sustained braking. This case swaps the front axle onto TTSPORT's Evolution ES6 kit, built specifically for the Alphard/Vellfire platform.

No flanges, no spacers, no wheel swap — this kit was engineered from the start to slide behind the factory 18-inch wheel on the Alphard and Vellfire.
Why It Works
TTSPORT ran mechanical simulation on the standard ES6 caliper and narrowed the body for this application, keeping the structure stiff enough for six-piston clamping force while trimming the width down to what the OEM wheel spokes allow.
- Forged, two-piece construction with a through-bolt reinforcement bar — the first time TTSPORT has used this bar on this application — adds structural strength and durability under repeated hard use.
- Two-piece heat-dissipating pistons pull heat away from the fluid faster, helping keep pedal feel consistent instead of going long and soft after repeated stops.
- A rigid fixed six-piston caliper reads driver input more directly than a flexing factory caliper, translating into a more linear, predictable pedal in hard or emergency braking.
