Does anybody know what size rear discs will be on my 2004 Golf?

Or know where i can find out, it doesn't say in the manual, only that there are 2 sizes available, and i'd rather not have to take the disc off an measure it

Thanks.

Do a search -it has been discussed before!

1. 255x10 MM
2. 286x12 MM
3. 260x12 MM

Not sure how 255x10 is possible, DBW's right--all MKIV Golf/Jetta/NB TDIs came with the 232x9mm rear solid rotors. However he's incorrect in saying it fits the A5. The A5 came with 260x12mm rear rotors on the TDI. :)

You are incorrect on the Rotors, I am sitting here reading straight of ETKA for the A5 Platform and the Golf (GOB) and Jetta (JEM) both list the rear rotors as "239x9, PN# b 1J0 615 601 C, brake disc"

Front rotors on the A5 are listed as "280x22, PN# b 1j0 615 301 P, brake disc (ventilated)"

There is an option listed under the JEM 2004 (A4) for a 256x22 ventilated disk, PN# 8N0 615 601 B and a Model identification of "PR-1KY"

The two rotors use a common caliper but different pads The thicker are the "PR-1KX" (non-ventilated 239mm) and the thinner for the ventilated (256mm) disc are listed under the "PR-1KY"

If you have the larger disc then you obviously have a quasi brake upgrade with vented rear discs.

The bad news is that it appears the larger brakes may use a different axle beam which permits the mounting and different caliper distance, one is listed as 18mm and the other 21.7mm.

Fair enough Pete, if you can get the 280mm MK4 size rotors on a standard MK5 then I'll supply them for free.

On a MK5 TDI:
Front 1K0615301T: 288x25mm (pads 3C0698151A)
Rear 1K0615601L: 260x12mm (pads 1K0698451F)

And if you think ETKA is right in all situations, you haven't been dealing with parts long enough!

well you can't be right because i've physically measured them.

in my haynes manual it says the two sizes they put on are the smaller size 255 x 10 and a bigger size that i presume they put on the gt's

maybe mines different cos i'm in the UK???

Quite possible, all I know of for sure is the North American cars :).

Give GSF a call - theres a dealer in Doncaster. Their web site lists 3 different front discs but only one rear disc. I use them a lot - good quality parts and good advice. (I use the Manchester North branch) Web link here points to locations/phone numbers
