2020-2026+ Land Rover Defender 90 / 110 / 130 / V8 / OCTA (L663) CCB Big Brake Kit — Genuine Akebono OEM Porsche 10-Piston (10N) Caliper Front + Genuine Brembo OEM Porsche 19Z 4-Piston Caliper Rear Setup
Defender L663 owners shopping this kit are usually trying to reduce iron rotor mass and brake dust while adding heat capacity for a heavy 4x4 that may tow, run large wheels, or be driven hard on mountain roads. This StopFlex Kit Upgrade uses 420mm front carbon-ceramic rotors with a Genuine Akebono OEM Porsche 10-Piston (10N) Caliper and 410mm rear carbon-ceramic rotors with a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper. Each kit is engineered to the customer’s exact Defender 90, 110, 130, V8, or OCTA trim so the brackets, rotor-hat offsets, caliper position, brake lines, and wheel-clearance checks match the vehicle being built.
- 420mm front and 410mm rear carbon-ceramic rotors give the Defender L663 more thermal mass than a cosmetic caliper swap while reducing rotating iron mass at both axles.
- The 420mm front rotor requires 21 inch or larger wheels; barrel and spoke clearance are confirmed because Defender 90, 110, 130, V8, and OCTA wheel offsets are not interchangeable assumptions.
- The kit pairs a Genuine Akebono OEM Porsche 10-Piston (10N) Caliper up front with a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper in the rear, so brake torque distribution is engineered as a complete front/rear system.

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 420 mm front rotor, so the minimum wheel size is 21". Wheels under 21" 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 axle uses the exact Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, giving the 420mm carbon-ceramic rotor a long, multi-piston pad sweep for stable clamping force and a firm pedal under repeated stops. Because it is a genuine OEM-derived Porsche caliper rather than an anonymous aftermarket casting, the body architecture, bridge stiffness, and pad support come from a production performance application. StopFlex mounts it with Defender L663-specific brackets and rotor-hat offsets after the exact trim and wheel package are confirmed.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo OEM Porsche 19Z 4-Piston Caliper on a 410mm carbon-ceramic rotor to keep rear brake torque and thermal capacity matched to the front upgrade. EPB integration is handled in the rear package so the Defender’s factory electronic parking brake function is retained where applicable.
Front & rear, engineered together: This kit is engineered as a front and rear brake system, not a front-only caliper conversion added to stock rear hardware. Matching the 10-piston front caliper, 4-piston rear caliper, 420mm front rotor, 410mm rear rotor, pads, hats, and lines helps preserve stable brake bias, ABS behavior, and chassis balance on the heavy L663 platform.
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 fit my exact Defender 90, 110, 130, V8, or OCTA?
The kit is built only after your exact L663 configuration is confirmed. StopFlex does not assume one bracket or hat offset fits every Defender chassis name; body style, trim, brake package, hub geometry, and wheel specification are checked before production.
What wheel size do I need for the 420mm front rotor?
The 420mm front rotor requires at least a 21 inch wheel. A 21 inch diameter is only the starting point; spoke shape, barrel profile, wheel offset, and spacer use must also be checked against the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper.
Will the electronic parking brake still work?
Yes, the rear portion of the kit is engineered around the Defender L663 factory EPB system where fitted. Rear caliper mounting, line routing, and service-mode requirements are handled as part of the confirmed vehicle build rather than treated as a generic rear brake swap.
Why choose carbon-ceramic on a Defender instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass while adding high-temperature stability for a heavy SUV that may tow, run large wheels, or see repeated downhill braking. This kit also gives the L663 a matched 420mm front and 410mm rear package instead of adding front brake torque without correcting the rear system.
