Mercedes-Benz Vito Big Brake Kit Upgrade / TTSPORT Evolution Series ES6
A Mercedes-Benz Vito running shuttle or cargo duty spends a lot of time fully loaded, and that extra weight lands squarely on the brakes every time the vehicle slows down. The factory calipers and rotors weren't sized with that repeated load-and-stop cycle in mind, so this build swaps in a TTSPORT front-and-rear package built around the Evolution Series ES6 six-piston front caliper and the EP4 electromechanical four-piston rear caliper, both paired with 355 mm carbon-ceramic rotors and running behind the Vito's factory 18-inch wheels.

Why It Works
A loaded Vito puts most of its braking demand on the front axle, which is why the ES6's staggered 27/32/38 mm pistons matter: the three sizes control how clamp load builds across the leading and trailing edges of the pad, instead of dumping all the pressure at one point. The two-piece forged aluminum caliper body flexes less than a stamped or thinner-wall housing under that same hydraulic load, so more of the pedal's pressure goes into clamping force instead of stretching the caliper.
Rear duty falls to the EP4, a four-piston electromechanical caliper that keeps the electronic parking brake built into the same unit rather than adding a separate parking-brake mechanism. Front and rear both run 355 mm carbon-ceramic rotors, which hold heat better and weigh less than a same-sized iron rotor — useful on a vehicle that's braking with real payload behind it, over and over, on a shuttle or delivery run.
- More thermal capacity front and rear for repeated stops under load
- Firmer, more direct pedal feedback from the forged ES6 caliper body
- More even front pad loading from the staggered piston sizing
- Reduced rotating and unsprung mass versus similarly sized iron rotors
- Electronic parking brake function retained through the EP4's integrated actuator
- Fits behind the Vito's factory 18-inch wheels once the 99 mm spoke clearance is confirmed
