I was just wondering what the differences are between the RS rear brakes and the Octavia rear brakes.

I know that the RS are ventilated, but how about size, calipers, brake pad etc..

Christian,

The brakes are bigger, I can't remember by how much though, I'll try and find out. They are also thicker due to being vented. Pads are the same for all Octavias (front and rear).

Re the KWs in your sig. No-one keeps Varient 3 in stock, they are made to order.

And the rear brakes on the Octavia are drums instead of discs...

Rob.

drums?

maybe early ones and non turbo ones, the rest are discs all round

Yeah, I know, I was just being picky about the idea of there only being RS and non-RS Octavias... :p

Rob.

Sorry, just for clarity; there are RS, non-RS and peasant spec

2002 Octavia rear disc sizes:

232x9mm (except 4X4 and RS)

4X4 = 239x9mm

RS = 256x22mm ventilated

thanks for the info, just wondering about the caliper, would I need to change that aswell??

Yes.

anyone have a rough estimate on the price for 2 x rear rs calipers and disc??

How was the trip back to Norway after Jabba...?

Is there much snow over in Bergen ?

Hi Christian.

do you know when you're going to be back at Jabba for the brakes and suspension?

How was the drive back to Norway...via Doncaster, Czech Republic and Denmark?

Cheers.

Adrian.

I am going back to Jabba around the 25th of January.

The drive was really something. The UK was quite alright as I never went above 110

just wondering about the caliper, would I need to change that aswell??

Just to correct the learned moderator who said "yes", the answer is no.

The same pads are used on all Octavias. It is the mounting point for said callipers that is different. You would need to get new mounting brackets made up which move the callipers in relatiuon to the hub.

Care to elaborate on that?? :confused: Are those mentioned brackest easy obtainable?? What is the easiest procedure to change the back brakes to the RS??

2 ways of doing it:

1. buy a RS rear hub as it has the mounts built in

2. several companies make a brake mounting kit. Usually consists of a piece of metal with 2 holes at either end that is used to shift the calliper outwards. Brembo and AP use these for their kits as it saves doing 1. You could go to a local metal fabricator/machine shop and get them to make up the 2 mounts for you.

Hope that helps.

I am always happy to be corrected by my more learned friend whose grasp of ETKA and all matters mechanical is far superior to mine. I was obviously confused by the fact that the 'standard' Octavia and RS have different part numbers listed for the brake calliper housings and for the brake carriers with pad retaining pin.

my car is a 2003 production and has drum breaks at the rear. but it's a tdi ambiente not elegance or l&k. that means it does not have to be old to have read drum brakes :P.

Hmmm Jon so you mean the caliper pistons have enough travel to soak up an extra 13 mm of disk thickness too? Sounds a lot .... :scratchch

Nick,

Part number for "standard" Octavia rear caliper assembly is:

1J0 615 423B (left)

1J0 615 424B (right)

Part number for 4x4 Octavia rear caliper assembly is:

1J0 615 423B (left)

1J0 615 424B (right)

Part number for Octavia RS rear caliper assembly is:

1J0 615 423 (left)

1J0 615 424 (right)

Strange eh?

Just to clarify for you I've uploaded the relevant pages for;

Standard rear

4x4 rear

RS rear

From those pics they do indeed look all the same - including the disc, which we know isn't. The part numbers do seem slightly different - the "B" is missing from the RS part numbers. It would seem that the difference in the discs between standard and RS that requires different housings must therefore be offset, rather than thickness. Thanks for the links.

Nick,

the difference is the B at the end of the part number, as the RS ones are green. I believe the B denotes "black". It's wierd though.

Looking at the discs, they are different part numbers, and the sizes are different (it gives the disc size on the right hand side)

To clarify matters further, the RS part numbers quoted should start with 1U0... not 1J0....
