Hi All,

Happy New Year!

I know there are lot of threads on this - I've spent some of this morning reading them. However, I just cannot get my head around which parts exactly I need for my car.

I've had advisories on the past two MOT's - Rear Brakes Scored or Pitted (told they are "lipping") and the latest one, Front Brakes as well. Planning on keeping the car for another 18 months, so I think it makes sense to just get all of them done.

I'm not prepared to do the work myself. I know there are plenty of guides, but I've decided I'm not going to attempt this. However, I've found a couple of garages happy to just charge labour to fit parts I supply, so I believe there is money to be saved here - I get 4 discs and all new pads at the prices you can online and then I just pay for some labour.

Alas, this is where I run into issues and I cannot find exactly what I'm looking for.

 

What I know for a fact is the car came from the factory with the following parts:

 

Front Brakes (1LG) - 340mm x 30mm (Vented and perforated (think perforated is the correct term - the "holes" in the disc)

Rear Brakes (1KT) - 272mm x 10mm (Solid)

 

The rear brakes seem simple enough - any number of searches brings me back items that look exactly the same. However, I am still looking for exact mart numbers if someone can help.

The front brakes are proving to be more difficult. I search, I make sure they are the correct size (because reg search alone gives me different size options) but none of them, with the exception of 2 Brembo discs, are showing the "hole" pattern on the disk itself, they all appear (from the pictures) to be a solid disc.

 

I'm told that TRW are almost certainly the OEM manufacturer for these discs, so I assumed that I'd be able to find some discs from them that match.

At autodoc for example, I can only find a single TRW disc showing at 340mm x 30mm and that is vented, but not perforated.

 

Would anyone be so kind as to either link me to the actual products or, be able to give me some manufacturer part numbers, for TRW discs (if these are the likely OEM - so a good match) for my car?

Would anyone also be able to advise on Brake Pads too?

 

Cheers All.

The OEM TRW front disks were vented but NOT perforated

Hi,

 

Cheers for the response - so that alone would indicate that the disc on my car were not TRW from the factory but some other OEM.

So, the perforation isn't going to be a requirement - just a design thing of whatever manufacturer supplied these discs to the factory.

The way I'm seeing it - promise this will be the last question (probably) my couple of choices would be:

 

Brembo (if I wanted to retain the perforation look)

https://www.autodoc.co.uk/brembo/15251183

https://www.autodoc.co.uk/brembo/7887431

https://www.autodoc.co.uk/brembo/7624600#brake-pad-set

£410

 

TRW (An OEM - just solid discs as opposed to the perforation I currently have on the fronts)

https://www.autodoc.co.uk/trw/7014270

https://www.autodoc.co.uk/trw/7489066

https://www.autodoc.co.uk/trw/7489103#brake-pad-set

£266

I'm sure you will be good either way.  There is a reason why the Brembo discs are more expensive - better quality materials that don't wear so badly, but it ultimately depends on your budget.

Remember to change the pads to the same manufacturer at the same time and ideally do a brake service on the car (clean, lubricate slider pins etc).

 

I wouldn't bother with drilled (perforated) discs where the car didn't come with them from the factory.

 

Pads don't need to be the same manufacturer, but I would choose disc/pad manufacturers carefully (as with most car parts!). The pads you have linked to say they are for 288 or 312mm diameter discs but the front discs are 340mm, so they won't fit (unless you're sure it's an error in the listing).

 

Halfords have got Pagid front discs at £64.35 each at the moment. Cheaper than the TRWs you have linked to and Pagid are a fairly well trusted brand (and supply OEMs).

Just spotted this bit of your OP. In my experience there's a lot of variance in MOT testers. My gf had advisories on her previous car for worn front brake discs. She doesn't drive hard, the car was on 45k and I measured the thickness of the discs with a caliper and they were only about half worn, so should have had another 30k+ miles left in them which would have been 4+ years with her mileage.

 

In my experience disc brakes should last 60k+ miles. Hard driving, urban driving or infrequent use (allowing corrosion to build up) are the main factors that would reduce that.

 

I'd recommend you get a caliper and measure them yourself, or at least get a garage to measure them / give a second opinion before spending a load of money for work that might not be necessary.

Thank you for that.

I had settled on the cheaper TRW - must admit, I hadn't even thought about Halfords for parts.

Both Front & Rear Pagid at Halfords are cheaper and they are currently running 10% off car parts - £196.50 for all the discs seems like a good price, so tempted to pick those up.

 

Pads are more pricy at Halfords and they don't list a 340mm Pagid set, so may source those elsewhere.

Thank you for this.

I first had an advisory on "lipped" rear brakes in 2023 and got the same advisory in 2024, along with the same for the front.

Car is at just over 60k miles - it is also a "lock down vehicle" where it spent a lot of time not going anywhere during the pandemic. Brakes feel OK, but looking at them, I can physically see the lipping.

 

As advised, I might go and do a measurement. In the grand scale of things, if I can find a garage willing to fit parts I buy - £400 all in for all 4 corners doesn't seem like a bad investment for the equally most important part of the car along side tyres.

Guys - I have one final question!

I'm about to hit the go button on Pagid Disc & pads. Halfords don't seem to have the rear pads, but I can source those elsewhere.

However - do the rear pads not have wear indicators?

 

I popped along to Euro Car Parts and fed in all my details - found the rear pads (272mm) but all of them are coming back as "Not prepared for wear indicator".

Just wanted to make sure that is the case before I get them ordered.

 

Cheers again.

No wear indicators on the rear pads.
