Hyundai i20 Brake Fluid
Brake Fluid for the Hyundai i20 — new, used and aftermarket stock, quoted once we know which i20 you are running
What Are Hyundai i20 Brake Fluid?
Brake fluid transmits foot pressure from the pedal to the calipers via the hydraulic lines on your Hyundai. Modern i20, Tucson and Creta models run DOT 4 spec, which absorbs moisture over time — two years of Durban humidity or Highveld rain and the boiling point drops enough to feel it on long mountain descents.

How we match brake fluid to your i20
What changes across the range
Sold here across PB, then GB, then the current BC3, the i20 is not one car for parts purposes — it is several.
The PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it.
Worth knowing: the i20shares its Kappa and Gamma engine families with the Kia Rio.
What we check on brake fluid
- •The generation code, because i20 parts lists split on it
- •The engine family — this i20 was sold with Kappa 1.2, Gamma 1.4 and Kappa 1.0 T-GDi (N Line)
- •The derivative and whether the car has been fitted with non-standard wheels, which can rule out some caliper and disc combinations
- •Whether the car is pre- or post-facelift within its generation
In South Africa the i20 is mostly a high-mileage commuter hatch that spends its life in stop-start city traffic, which is why wear items move faster on an i20 than on almost anything else Hyundai sells here. That is the wear pattern we stock and source against.
Hyundai i20 Brake Fluid FAQs
Will brake fluid from another i20 fit mine?
Not automatically. The i20 sold in South Africa as PB, then GB, then the current BC3, and the PB and GB are different cars underneath despite the shared badge, so a part listed simply as "i20" is not automatically the right one — the generation code decides it. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
What should I send you when asking about i20 brake fluid?
The VIN is the single most useful thing — a photo of the plate is fine. Failing that, the generation code and the engine code off the block. The i20 ran as PB, then GB, then the current BC3, so the generation is what narrows the search.
Which brake fluid does a Hyundai take?
Hyundai specifies DOT 4 brake fluid across the modern range — i20, Tucson, Accent, Creta, Sonata and Santa Fe all use it, and the official hyundai.co.za site confirms it. Never put DOT 5 silicone fluid in: it is not compatible with the ABS seals, and that is a mistake you find out about at the worst moment.
Can DOT 3 and DOT 4 be mixed?
Technically they mix — both are glycol-based. But DOT 3 has a lower boiling point, so topping up with it drags the whole system down to the weaker spec. If someone has already done it, a full flush with fresh DOT 4 is the fix rather than another top-up.
How often does Hyundai brake fluid need changing?
Every two years or 40,000 to 60,000 km, whichever comes first, per Hyundai's own service schedule. The South African wrinkle is humidity: coastal cars absorb moisture faster, so on the KwaZulu-Natal or Cape coast stick to the two-year interval even if the mileage says otherwise.
What does a brake fluid change cost?
SA retail DOT 4 is affordable — brands like Liqui Moly and Castrol come in 500 ml bottles, with budget options around R65.86 and Castrol around R99. A full bleed adds roughly an hour of workshop labour, which is why it is worth bundling with a pad change rather than doing on its own.
How do I know the fluid is past it?
A spongy pedal on a long descent is the one that matters — that is moisture in the fluid boiling and putting vapour in the line. Dark or black fluid and ABS cutting in more readily in the wet point the same way. A cheap test strip at any workshop reads the water content in seconds.
