Honda genuine brake fluid DOT 4 08203-99938HE

Honda DOT 4 brake fluid 0.5L – genuine 08203-99938HE

Genuine Honda DOT 4 brake fluid (part number 08203-99938HE) is the original brake fluid specified by Honda for many models on the European market. It is engineered to meet Honda’s factory requirements for ABS/ESP systems and to provide a stable, predictable brake pedal feel in everyday driving.

Why choose genuine Honda brake fluid DOT 4?

The braking system is one of the most important safety components in any car. Using genuine Honda brake fluid helps the system work exactly as Honda intended:

• meets Honda specifications for DOT 4 brake systems with ABS and stability control,
• provides a high boiling point to reduce the risk of brake fade during hard braking,
• maintains a firm and consistent brake pedal over a wide temperature range,
• is fully compatible with seals, hoses and components used in Honda brake systems,
• contributes to reliable, trouble-free operation of the master cylinder, calipers and ABS modulator.

Instead of guessing with a generic DOT 4, this genuine fluid is a safe choice when you want your Honda brake fluid to deliver the same feel and performance as it did from the factory.

Where can Honda DOT 4 brake fluid be used?

This Honda DOT 4 brake fluid 08203-99938HE is suitable for Honda vehicles where the owner’s manual or reservoir cap specifies DOT 4. In practice this includes many versions of popular models such as Honda Civic, Honda Accord, Honda CR-V, Jazz and HR-V, depending on engine, year and market.

If you drive a Honda Civic, Accord or CR-V and your documentation confirms DOT 4, this genuine Honda DOT 4 brake fluid is a compatible choice for routine brake fluid changes and top-ups. For any doubts, always refer to the owner’s manual or consult a Honda specialist.

DOT 4 vs DOT 3 in Honda brake systems

Both DOT 3 and DOT 4 are glycol-based brake fluids, but DOT 4 usually offers a higher boiling point and better resistance to high temperatures. Historically, some older Honda models were filled with Honda genuine brake fluid DOT 3 and service information often mentions Honda brake fluid DOT 3 for those cars.

On the European market, Honda has effectively moved to DOT 4 as the standard brake fluid for most current models, and genuine Honda DOT 4 now replaces DOT 3 in many service situations – as long as the owner’s manual allows DOT 4. When you compare DOT 4 vs DOT 3, it is not about “better or worse” in general, but about using the grade that Honda specifies for your particular car.

If your manual lists only DOT 3, use a quality fluid that meets that spec. If it allows DOT 4, this genuine Honda DOT 4 brake fluid can be used as an updated replacement.

Brake fluid change interval and service tips

Brake fluid absorbs moisture over time, which lowers its boiling point and can lead to a soft pedal or reduced braking performance. Even the best Honda brake fluid DOT 4 needs regular replacement. For most vehicles, a brake fluid change every 2–3 years is a good rule of thumb, regardless of mileage.

• regular Honda brake fluid change helps maintain safe braking performance,
• reduces the risk of vapor lock and brake fade under repeated hard stops,
• protects internal brake components from corrosion caused by absorbed moisture.

The 0.5 L bottle is ideal for topping up or for use together with additional bottles during a full Honda brake fluid replacement, depending on the bleeding procedure and the specific model.

FAQ – Honda DOT 4 brake fluid 08203-99938HE

Which brake fluid for Honda Civic, Accord or CR-V?
The correct brake fluid for Honda Civic, Honda Accord or Honda CR-V depends on model year and market. Older cars sometimes used Honda genuine brake fluid DOT 3, while most newer European models specify DOT 4. Check the owner’s manual or the marking on the reservoir cap; where DOT 4 is approved, this genuine fluid 08203-99938HE is a suitable choice.

Honda DOT 4 vs Honda DOT 3 – which should I use?
In Europe, DOT 4 is now the standard for most current Honda models and often replaces DOT 3 during service, provided the car allows DOT 4. Use DOT 3 only when it is explicitly required and DOT 4 is not listed as an option. Always follow Honda’s recommendation for your vehicle.

How often should Honda brake fluid be changed?
For most Hondas, a brake fluid change every 2–3 years is recommended. Time is more important than mileage here, because moisture enters the system gradually. Regular changes are a simple way to keep braking performance consistent and safe.

What does a Honda brake fluid change cost?
The Honda brake fluid change cost or Honda brake fluid replacement cost depends on labour rates, the specific model (for example a Honda Accord brake fluid change vs a smaller Civic) and the bleeding procedure used. In most cases, the fluid itself is only a small part of the total bill – the main cost is workshop time, so it makes sense to use genuine Honda fluid during the service.

Can I top up with generic DOT 4 instead of Honda brake fluid?
In an emergency, topping up with a quality generic DOT 4 may be acceptable. For long-term use, however, it is better to flush the system and fill it completely with genuine Honda DOT 4 brake fluid that matches the factory specification. This avoids mixing different additive packages and keeps the brake system as reliable as possible.
