2013-2021 Land Rover Range Rover / SV / SVAutobiography (L405) CCB Big Brake Kit — Genuine Brembo GT BM8 8-Piston Caliper Front + Genuine Brembo GT BM4 4-Piston Caliper Rear Setup
This StopFlex kit is for L405 Range Rover SV and SVAutobiography owners who want a full brake system upgrade instead of another heavy iron-disc service on a large, high-output SUV. The front axle uses a 410mm carbon-ceramic rotor with the Genuine Brembo GT BM8 8-Piston Caliper, while the rear uses a 380mm carbon-ceramic rotor with the Genuine Brembo GT BM4 4-Piston Caliper, giving the vehicle more thermal capacity, lower brake dust, and reduced rotating mass compared with an iron big-brake package. Each kit is built against the confirmed model year, trim, hub geometry, wheel size, and spoke clearance so the bracket stack and rotor-hat offset match the actual L405 being upgraded.
- 410mm front carbon-ceramic rotors require 21-inch or larger wheels on the L405; wheels under 21 inches will not clear the package, and spoke clearance is checked separately.
- The front upgrade is built around the Genuine Brembo GT BM8 8-Piston Caliper, matched to the weight and front brake demand of the full-size Range Rover L405.
- The rear package uses a 380mm carbon-ceramic rotor with the Genuine Brembo GT BM4 4-Piston Caliper so rear torque contribution is engineered with the front system, not treated as a cosmetic add-on.

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 410 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 Genuine Brembo GT BM8 8-Piston Caliper, giving the 410mm rotor a broad, stable clamping footprint for repeated high-energy stops in a heavy L405 chassis. Brembo GT hardware is a proven performance-brake platform, and this caliper’s rigid multi-piston architecture supports consistent pedal response when the carbon-ceramic disc is hot. StopFlex does not rename or substitute this caliper; the kit is engineered around the Genuine Brembo GT BM8 8-Piston Caliper specified for this build.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo GT BM4 4-Piston Caliper with a 380mm carbon-ceramic rotor to support rear brake torque, vehicle stability, and front-to-rear balance under hard braking. The L405 factory electronic parking brake is accounted for during rear system engineering so parking-brake function is not ignored in the conversion plan.
Front & rear, engineered together: The 410mm front and 380mm rear carbon-ceramic packages are specified together so brake torque, thermal capacity, pad selection, and hydraulic behavior are treated as one system. On a tall, heavy Range Rover L405, matching the rear upgrade to the front avoids the common front-only problem of added front bite without the rear contribution needed for stable deceleration.
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 Range Rover L405 SV or SVAutobiography?
Fitment is not treated as a platform-wide L405 assumption. StopFlex confirms the exact model year, trim, hub geometry, existing brake package, wheel size, and spoke profile before producing the brackets, rotor hats, caliper mounting, lines, and hardware for that vehicle.
What wheel size do I need for the 410mm front rotor?
The 410mm front rotor requires 21-inch or larger wheels. Wheels under 21 inches will not clear the rotor, and even with 21-inch or larger wheels, spoke clearance must be checked against the Genuine Brembo GT BM8 8-Piston Caliper before the kit is built.
Will the electronic parking brake still work?
The L405 Range Rover uses a factory electronic parking brake, so the rear conversion is engineered with EPB retention and service requirements in mind. Final compatibility is confirmed from the exact vehicle data because rear parking-brake hardware and brake service procedures must be respected during installation.
Why move from iron brakes to carbon-ceramic on this Range Rover?
On a full-size L405, carbon-ceramic rotors reduce brake dust and rotating mass while adding heat capacity for repeated braking compared with a conventional iron service package. The benefit is most noticeable on heavy street use, mountain driving, towing-adjacent heat loads, and owners who want cleaner open wheels without giving up a matched front and rear big-brake system.
