What disc size

[IANTDI]

Can any body tell me what size discs I require for my golf gttdi 02 plate ?:confused:

[Crasher]

They will be 288-mm but if you want to make sure, PM me your chassis number and email address and I will send you the info.

Normally 288mm for the front, and 256mm for the back. (unless you have the PD100 model which is 280mm on the front.)

232 at the back, the only FWD model that has 256 vented rears is the 1.8T Anniversary.

Crasher to the rescue :biglaugh:

From your chassis number I can confirm your car uses 288x25 fronts and 232x9 rears. The rear discs are 1J0 615 301 C and are a very reasonable £27.14 each inc. VAT from VW. It is quite acceptable to change the rear discs and pads without doing the fronts. I would also recommend that you buy either TEXTAR or genuine VW pads as they are the only ones I know of that have the sticky backing that you need for the outer rear pad. The sticky backing should not be exposed on the inner pad. You need a caliper wind back tool to reset the rear calipers.

Mintex brake pads also have sticky backing....

I got a set recently from a shop advertising on ebay, for £41.99 (Discs and pads) And the caliper windback tool is as "laser 1314" and you need adapter no.1/2 (reversable) costs around £20, but if you live near manchester, feel free to borrow mine.

Drop me a PM if you wish.

I like the VW discs because of the Dacromet anti corrosion coating.

Cheers for the help , but what is this sticky backing ? is it just like putting on copper grease ?

[Crasher]

Absolutely the opposite. The outer pad must be stuck to the two fingers of the caliper housing so that when the pedal is released, the pad is pulled away from the disc. The caliper inner clamping surface must be spotlessly clean. Anti seize is still used on the sliding surfaces and the piston face of the inner pad. The inner pad used to be stuck to the piston but as the piston rotated the seal stuck to the pad and ripped, the cause of a lot of caliper failures, so this practice was discontinued.

[IANTDI]

Just finished fitting the discs and pads and would just like to say thank you to you all for the help

Note what you say about the sticky pad Crasher, but it seems to me that these are to hold the pads in place to help assembly when the pads are being replaced. When the brakes are not applied all pads will and should rub sugly on the disc without binding otherwise there would be a delay before they made contact with the disc.

[Crasher]

It is nothing to do with assembly; the pads are installed into the carrier before the caliper is fitted. If the outer rear pads aren’t fitted with a sticky backing, they rub on the discs and howl. When the pedal is released, the piston retracts slightly and pulls the pad away from the disc. VAG used to do this on the inner pad as well but it prevented the piston from rotating to self adjust and caused the boot to twist and rip.

Following on from this, I'm about to attempt my front discs and pads myself (gulp) and just wanted to make sure my 1999 gti turbo uses 288mm discs? Am I likely to get myself into a whole world of hurt when I attempt this? Thanks guys.

[Crasher]

Yes they are 288's and if you mess it up you should hang your overalls up for good, it is very easy. The 280’s can get you into trouble but not the 288’s.

[random_dave_1]

Well I never had any overalls in the first place but I'll give it a go, what's the worst that could happen! Apart from the brakes falling off on the M1 of course! Cheers, I've ordered some 288s with pads now.

[Crasher]

The worst that could happen is you have an accident due to a mistake but as for conventional **** ups I can't see any with that job, if you have some experience you will be fine.
