Pad brek itu rosak.

In Malay, demonstratives such as ini and itu usually come after the noun phrase they modify.

So:

• pad brek itu = that brake pad / the brake pad
• kereta itu = that car
• rumah ini = this house

This is different from English, where this/that comes before the noun.

In this sentence, itu points to a specific brake pad already known in the context. Depending on the situation, it can sound like either that brake pad or the brake pad in English.

Malay often leaves out the equivalent of is/are in simple sentences like this.

So:

• Pad brek itu rosak. literally looks like Brake pad that damaged
• but naturally means That brake pad is damaged or The brake pad is broken

This is very normal in Malay. When describing something with an adjective or stative word like rosak, you usually do not need a separate word for is.

It is often taught as an adjective meaning broken, damaged, or faulty, but in Malay it also behaves a lot like a stative verb.

That is why a sentence like:

• Pad brek itu rosak.

is complete by itself, without needing a word for is.

So for a learner, the safest way to think of rosak is:

• it describes a state
• it can function directly as the predicate of the sentence

Other similar Malay words work the same way:

• besar = big
• kecil = small
• panas = hot
• sejuk = cold

The sentence follows the common Malay pattern:

• Subject + predicate

Here:

• pad brek itu = the subject
• rosak = the predicate

So the structure is:

• Pad brek itu
  • rosak
• The brake pad
  • is damaged

This is very common in Malay and is one of the basic sentence patterns learners see early on.

By itself, pad brek does not clearly mark singular or plural.

So depending on context, it could mean:

• the brake pad
• the brake pads

In real usage, context usually makes it clear.

If you really want to show plurality, Malay can do that in other ways, for example:

• by adding a number
• by using context
• sometimes by reduplication, though that is not always the most natural choice for technical items

So in this sentence, learners should understand that Malay often leaves number unspecified unless it matters.

Yes. They are standard Malay words, but they are loanwords.

• pad comes from English
• brek is borrowed from English brake, but spelled in a Malay-style way

Malay uses many loanwords, especially for modern, technical, mechanical, and scientific vocabulary. So a sentence like this is perfectly normal Malay.

You may also hear some regional variation. For example, some speakers use terms influenced by neighboring languages or local habits, but pad brek is a normal and understandable form.

It can feel like either one in English, depending on context.

Literally, itu is often taught as that. But in actual sentences, noun + itu can also function a bit like a definite noun phrase, similar to the ... in English.

So:

• pad brek itu rosak

could be understood as:

• that brake pad is damaged
• the brake pad is damaged

If the speaker is pointing to a specific brake pad, that may be better. If the speaker is just referring to the known brake pad in the situation, the may sound more natural in English.

Yes, you can, but the feel changes slightly.

• Pad brek itu rosak. = a specific brake pad / the brake pad / that brake pad is damaged
• Pad brek rosak. = brake pad is damaged / brake pads are damaged / a brake pad is damaged, depending on context

Without itu, the noun phrase is less specific. In conversation, both can be natural, but itu helps show that the speaker has a particular brake pad in mind.

Yes.

• Pad brek ini rosak. = this brake pad is damaged
• Pad brek itu rosak. = that brake pad is damaged

The difference is the same basic idea as this versus that in English:

• ini = near the speaker
• itu = farther away, or less immediate in the discourse

Both still come after the noun in Malay.

A simple learner-friendly pronunciation guide would be:

• pad = like English pad
• brek = roughly brek, with a short e like in bed
• itu = ee-too
• rosak = ro-sak

A rough full pronunciation:

• pad brek ee-too ro-sak

A few useful notes:

• Malay spelling is fairly regular
• brek is pronounced more or less the way it looks
• r in Malay is usually a tapped or lightly rolled sound for many speakers
• stress is not as heavy or dramatic as in English

Yes, both are possible, but they add a nuance.

• Pad brek itu rosak. = The brake pad is damaged.
• Pad brek itu sudah rosak. = The brake pad is already damaged / has become damaged.
• Pad brek itu telah rosak. = The brake pad has become damaged. This often sounds a bit more formal or written.

So the original sentence is a simple neutral statement of condition. Adding sudah or telah can emphasize that the damaged state has already happened.

Mostly, rosak is used for things that are damaged, broken, spoiled, or not functioning properly.

For example:

• telefon rosak = a broken phone
• mesin rosak = a broken machine
• jalan rosak = a damaged road

It can also be used more broadly, depending on context, but for learners the safest core meaning is:

• physically damaged
• faulty
• not working properly

So in Pad brek itu rosak, it very naturally means the brake pad is damaged or faulty.
