Hy vervang die rem; die voertuig rem goed.

Because rem can be both a noun and a verb in Afrikaans.

• In die rem, rem is a noun: the brake
• In die voertuig rem goed, rem is a verb: brakes

This is quite normal in Afrikaans. English does something similar with words like brake:

• the brake = noun
• the vehicle brakes = verb

So the sentence is a neat example of the same word being used in two different grammatical ways.

Vervang means replace.

In Afrikaans, verbs usually do not change form depending on the subject. That is much simpler than English.

So you get:

• Ek vervang = I replace
• Hy vervang = he replaces
• Ons vervang = we replace

English adds -s in he replaces, but Afrikaans does not. The verb stays vervang.

In Afrikaans, die is the normal definite article meaning the.

Unlike languages such as German or Dutch, Afrikaans does not have grammatical gender in its articles. So you do not need to learn different words for the depending on whether a noun is masculine, feminine, or neuter.

That means:

• die rem = the brake
• die voertuig = the vehicle

The article is the same in both cases: die.

Afrikaans does not need a helper verb like English does in a normal present-tense statement.

English says:

• the vehicle brakes well

and only uses does in certain situations, such as emphasis or questions:

• The vehicle does brake well
• Does the vehicle brake well?

In Afrikaans, the simple present is usually just:

• die voertuig rem goed

No extra helping verb is needed.

Here goed means well, and it functions adverbially, describing how the vehicle brakes.

Afrikaans often places this kind of word after the verb:

• Hy werk goed = He works well
• Die voertuig rem goed = The vehicle brakes well

So the order is very natural:

• subject: die voertuig
• verb: rem
• manner word: goed

Literally, goed is related to good, but in this sentence it is best understood as well.

So:

• goed after a verb often works like English well
• Die voertuig rem goed = The vehicle brakes well

This is a common thing in Afrikaans. A word that looks like an adjective in English may also be used naturally in a way that English would translate with an adverb.

Yes. Both parts are straightforward main clauses, and the word order is normal:

• Hy vervang die rem
• die voertuig rem goed

In simple main clauses, Afrikaans usually follows a pattern similar to English:

• subject + verb + object / other information

So:

• Hy = subject
• vervang = verb
• die rem = object

and

• die voertuig = subject
• rem = verb
• goed = adverbial word

Nothing unusual is happening here.

The semicolon links two closely related clauses.

The two ideas are connected:

• first, he replaces the brake
• second, the vehicle brakes well

A semicolon shows a stronger connection than a full stop, but keeps the two clauses more separate than en would.

You could also see other punctuation in similar contexts, depending on style. The semicolon here suggests a clear relationship between the repair and the result.

Yes, die rem is singular: the brake.

If you want the plural, Afrikaans often uses remme:

• die remme = the brakes

So for example:

• Hy vervang die remme = He replaces the brakes

Learners should note that plural formation in Afrikaans is not always fully predictable, so it is worth learning noun plurals as you meet them.

Yes, voertuig means vehicle, and it is broader and a bit more formal or technical than car.

So:

• voertuig = vehicle
• motor or kar = car

Using voertuig makes the sentence sound a little more general or mechanical, as if talking about transport, maintenance, or technical performance rather than just an everyday car.

A rough guide for an English speaker:

• Hy: something like hay or hey, but shorter depending on accent
• vervang: roughly fur-FANGKH
• die: usually like dee
• rem: like rem in English, but with a clear rolled or tapped r in some accents
• voertuig: roughly FOOR-taykh or FOOR-tuikh, depending on accent
• goed: roughly khoot or ghoot, with the guttural Afrikaans g

The hardest sounds for English speakers are usually:

• the Afrikaans g sound in goed
• the vowel combinations in hy and voertuig

A native pronunciation model is especially helpful for these words.

Not perfectly. A word-for-word translation helps you see the structure, but natural English may differ slightly.

Word-for-word, it is roughly:

• He replaces the brake; the vehicle brakes good/well

But natural English would be:

• He replaces the brake; the vehicle brakes well.

So the structure is close to English, but you still need to watch for things like goed, which is translated naturally as well here.
