Can anyone tell me if the discs on a 1.9tdi are the same as those on a 1.9sdi?

 

Cheers all

My mothers 1.9 TDi had 256mm discs on the front but I'm unsure if their the same as the SDi ones. HTH

So did you try fitting those sdi 

SDI's normally have 280mm, where the caliper carrier is a cast part of the wheel hub carrier. The 288's use a bolt on caliper carrier, so you can't change from one to the other without changing the hub carriers. 

Well this all sounds a bit weird :-  I would think lowest power cars have 239mm discs with no carrier, mid range powered cars have 256mm discs with no carrier and higher powered cars have 288mm discs with a carrier.

 

So why would SDI have 280mm front discs and some TDI have 256mm discs?

 

Clarification and/or correction needed here to avoid someone buying wrong parts.

A tape measure would solve this in minutes, I have no idea why it's so difficult to Jack it up and whip a front wheel off to confirm diameter.

 

My money's on 239, the SDI is a complete slug and doesn't really need brakes at all.

Take wheel off, if the caliper has FSIII cast into it, it will be 256mm.

 

Check with a ruler/tape measure.

 

Alternative check the PR codes, usually on the sticker in the service booklet front cover or a sticker in the spare wheel well. .

 

1LQ,1LR 256mm

 

1LN,1ZH 288mm

 

1LB,1LM,9U0,9U1 239mm

1.9 SDI with ASY engine code has 256mm fronts, FS111 calipers, as far as I can see.

I don't think the front brake PR code will be on the data sticker, but worth a look.

 

ATD & AXR 1.9TDIs have 256/FS111

ASZ & BLT 1.9 TDIs have 288mm with C54 caliper

 

Old thread awakened in February for some reason, BTW.

Brake variants for Mk1 Fabia are all listed here FWIW: https://workshop-manuals.com/skoda/fabia-mk1/chassis/technical_data/brakes/brake_variants_and_their_assignment/

 

Looking through that list, only the 1.2 engines and the AZE & AZF- code 1.4MPIs have ambiguity where  239 or 256mm fronts might be found according to the list. All the other engine codes you should be able to tell what's on the car just from the list.

hi.can you tell me if i can replace my fs2 calipers with fs3 ones?does the bracket is the same?

thanks

Why would you bother, FS3 have larger discs which means better brakes, the calipers themselves are almost identical.

because my current fs2 calipers are sticky and rotten so as the rotors

since prices almost identical for the fs2 and fs3 parts,if the bracket is the same i would like to upgrade it to fs3 if possibe

The wheel bearing housings have a different part number, AG at the end for 239mm/FS2, AC at the end for 256mm/FS3.

That suggests to me that you can't switch easily.

how can i check it for sure?my engine code is bme which is listed on the page you linked at the ac line which corresponds with the fs3 caliper so maybe that model fitted with both versions so probably same carrier?

Look for the part number on the wheel bearing housing, you may only see a subset of the full number, but the AC/AG will be visible. On the inside if I remember right.

The 1.2 htps came with both set-ups. Our AZQ-engined one is PR code 1LB, 239mm/FS2.

its way too rusty to get any number from it

so if 1.2 is came with both setups doesnt it mean that the carrier is the same?

I don't think so, but I'll see if I can do some comparative measuring tomorrow, as I have FS2 and FS3 cars to hand. 

There's a Ukrainian website you can stick your VIN into that may give you your full car data, including front brake PR code, I'll find you the link, hang on...

The carrier can't be the same with different diameter discs.

Sometimes works, sometimes doesn't.

This is the truth of the matter. Here's a photo of the FS2 set-up with 239mm disc and corresponding carrier part of the wheel bearing housing:

 

The gap is less than 4mm.

 

A 256mm disc won't fit.

crap 😞 then ill stick with the 239 system.the carrier change wont worth it

thanks for checking

also im at 186000 kms.when do i have to change the timing chain?cant find any info about change interval

There isn't a schedule for chain change, it's supposed to last the life of the engine.   It could be argued that it will, 'cos if it fails that's probably the end of the engine.

I'm actually in the process of changing mine, started yesterday.  The car is at 175k miles/280k km, and judging by the part number on the tensioner, was still on its factory stuff.

At first glance nothing looks particularly worn, but there's surely some elongation, will be interesting to compare old and new parts in detail.

It's a big job.

thanks.let me know the results.i know its a big job but if it fails it kills the engine.theres no rattling noise or anything suspicious from the engine so i guess im fine until 250k km if yours still holds up at 280k

Clean oil is important.
