2024-2026+ Toyota Alphard / Vellfire (AH40) CCB Big Brake Kit — Genuine Advics OEM Lexus 6-Piston Caliper Front + Genuine Brembo GT4 Rear Setup
The AH40 Toyota Alphard / Vellfire is a heavy luxury MPV, so repeated high-speed stops and mountain driving can push the factory iron brake package into heat, dust, and pedal-consistency limits. This StopFlex kit upgrades the front to a 400 mm carbon-ceramic rotor with the Genuine Advics OEM Lexus 6-Piston Caliper and matches the rear with a 380 mm carbon-ceramic rotor using one of three Brembo 4-piston caliper options. The payoff is higher thermal capacity, lower brake dust on large wheels, reduced rotor mass versus comparable iron hardware, and trim-confirmed fitment instead of a generic AH40 assumption.
- 400 mm front carbon-ceramic rotors require 20 inch or larger wheels on the AH40 Alphard / Vellfire; wheel-barrel and spoke clearance are verified before the kit is built.
- Front braking is handled by the Genuine Advics OEM Lexus 6-Piston Caliper, giving the AH40 a large OEM-derived fixed-caliper upgrade instead of a cosmetic caliper cover or stock single-sliding setup.
- Rear matching uses 380 mm carbon-ceramic rotors with Brembo V4, GT4, or GTS4 4-piston caliper options so rear torque, stability, and visual balance are engineered with the 400 mm front package.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 400 mm front rotor, so the minimum wheel size is 20". Wheels under 20" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses the exact Genuine Advics OEM Lexus 6-Piston Caliper with a 400 mm StopFlex carbon-ceramic rotor. Its six-piston fixed-caliper layout spreads clamp load across the pad more evenly than a sliding caliper, which supports firmer pedal response and more consistent pad contact on a large AH40 brake package. Because this is a genuine OEM-derived Lexus/Advics caliper, it gives the kit factory-grade provenance while allowing StopFlex to engineer the brackets, hat offset, and line routing for the customer’s confirmed Alphard or Vellfire trim.
Rear Caliper (Balance)
The rear axle is matched with Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on a 380 mm carbon-ceramic rotor: V4 uses the Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 uses the Genuine Brembo GT | M4 4-Piston Caliper, and GTS4 uses the Genuine Brembo GT | S4 4-Piston Caliper. The rear package is engineered to support brake balance and vehicle stability under braking, with the AH40’s electronic parking brake requirements confirmed before production.
Front & rear, engineered together: The 400 mm front and 380 mm rear carbon-ceramic rotors are specified as a system so the AH40 does not receive a front-only torque increase that leaves rear response and stability behind. StopFlex matches caliper position, rotor-hat offset, pad compound, lines, and hardware to the confirmed vehicle so the front Advics and rear Brembo hardware work as one brake package.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact 2024-2026+ Alphard or Vellfire AH40 trim?
StopFlex does not assume fitment from the AH40 chassis name alone. Brackets, rotor-hat offsets, caliper position, line routing, and hardware are engineered after confirming your exact Alphard or Vellfire trim, drive configuration, hub geometry, and wheel specifications.
What wheel size is required for the 400 mm front rotor?
The 400 mm front carbon-ceramic rotor requires 20 inch or larger wheels. Wheels under 20 inches will not clear the rotor, and StopFlex also checks spoke clearance because the Genuine Advics OEM Lexus 6-Piston Caliper needs enough face clearance behind the wheel.
Will the electronic parking brake still work?
The AH40 Alphard / Vellfire uses an electronic parking brake, so rear fitment is confirmed before the kit is built. StopFlex engineers the rear Brembo 4-piston caliper package around the vehicle’s parking-brake configuration instead of treating the rear as a generic caliper swap.
Why choose carbon-ceramic rotors on an Alphard or Vellfire instead of iron rotors?
Carbon-ceramic rotors reduce brake dust, improve heat resistance during repeated heavy stops, and lower rotating mass compared with similarly sized iron rotors. On a large premium MPV such as the AH40, those gains matter for wheel cleanliness, pedal consistency, and steering response.
