BYD Seal

The BYD SEAL is an advanced, fully electric D-segment saloon. Because it is an electric vehicle, its braking dynamics differ from those of a conventional car with a petrol engine. The vehicle relies on a combination of regenerative braking and traditional friction brakes to slow down. This page provides a general overview of these systems and what is involved in maintaining them.

Work on a vehicle’s braking system is classified as dangerous work, as the brakes are a critical safety component. Never attempt to dismantle the braking system yourself. Always check your owner’s manual for maintenance schedules and confirm with an authorised BYD dealer or qualified workshop for any repair work. BYD’s own procedure applies to all brake servicing.

Regenerative vs friction braking

As a fully electric vehicle, the BYD SEAL employs regenerative braking. When the driver lifts off the accelerator pedal, the electric motor acts as a generator, converting the car’s kinetic energy back into electrical energy to recharge the 82.5 kWh Blade Battery. This process naturally slows the car down and significantly reduces the workload on the traditional friction brakes.

Despite the efficiency of regenerative braking, the vehicle is still equipped with traditional hydraulic friction brakes (brake discs and pads) on all four wheels. These are necessary for hard stopping, holding the vehicle at a standstill (via the Auto Hold function), and emergency situations such as when the Automatic Emergency Braking (AEB) system is triggered.

Warning signs of brake wear

Because the friction brakes are used less than in a non-electric car, the brake pads and discs can last considerably longer. However, they are still subject to wear, environmental corrosion, and potential seizing if not used vigorously on occasion.

Owners should be alert to warning signs that indicate a professional inspection is required. These signs may include a squealing or grinding noise when the brake pedal is pressed, a spongy feel to the brake pedal, the vehicle pulling to one side under braking, or a brake warning light illuminating on the 10.25-inch instrument display. If you notice any of these symptoms, read the dashboard message, check your owner’s manual, and arrange for a diagnostic check.

BYD SEAL brake pads repair

If an inspection reveals that the friction material has worn down to the minimum safe limit, a BYD SEAL brake pads repair will be necessary. This process involves safely lifting the vehicle using the correct jack points (especially critical due to the under-floor battery), removing the 19-inch alloy wheels, and replacing the worn brake pads with new, manufacturer-approved components.

Depending on the condition of the brake discs (rotors), they may also need to be replaced at the same time. This repair must be performed by a qualified technician to ensure the hydraulic system is not compromised and that all electronic sensors function correctly. Confirm with an authorised BYD dealer for the replacement of brake components.

iTAC and electronic braking controls

The braking system on the BYD SEAL is tightly integrated with its advanced electronic stability systems. The vehicle features iTAC (Intelligent Torque Adaption Control), which boasts a recognition speed significantly faster than conventional stability control systems. iTAC manages traction and stability by intelligently transferring torque and applying negative torque (braking) to individual wheels as needed.

Additionally, the standard Advanced Driver Assistance Systems (ADAS) suite relies on the braking hardware to execute functions like Automatic Emergency Braking (AEB), Rear Cross Traffic Braking (RCTB), and Front Cross Traffic Braking (FCTB). Proper maintenance of the mechanical brakes is essential for these safety systems to operate effectively.

Dealer-only brake work

Because of the integration with high-voltage systems, ADAS hardware, and electronic stability controllers, any deep diagnostic work or replacement of hydraulic lines, calipers, or the brake fluid itself is strictly dealer-only work. The brake fluid is hygroscopic (it absorbs moisture over time) and must be replaced according to the schedule in the owner’s manual. Confirm with an authorised BYD dealer to ensure this dangerous work is completed safely and that BYD’s own procedure applies.

Frequently asked questions

Does the BYD SEAL have regenerative braking?

Yes, as a fully electric vehicle, the BYD SEAL uses regenerative braking to recapture energy and slow the vehicle down, which reduces wear on the friction brakes.

Is a BYD SEAL brake pads repair something I can do at home?

No. Working on the braking system is dangerous work. You should confirm with an authorised BYD dealer or qualified workshop to have the brake pads replaced.

What should I do if a brake warning light comes on?

Check your owner’s manual to understand the specific dashboard message and book a diagnostic appointment with an authorised dealer immediately.

Is the BYD SEAL fully electric?

Yes, the BYD SEAL is a fully electric D-segment sports saloon and does not have a petrol engine.
