312mm brakes - Pictorial

[Lummox]

As the last thread seems to have dissapeared I have reconstructed the 312mm guide. Please feel free to make any comments if the guide isnt detailed enough and I will amend. As allways with anything mechanical on your car least of all brakes you are unsure about what you are doing get a profesional on the job.

The tooling required

12mm, 17mm and 18mm sockets
Breaker bar
Impact driver
Hammer
7mm allen key
Brake bleeder (Gunsons EZ bleed is perfect)
11mm spanner

The standard, rather tiny looking 288mm Fabia vRS front set up (the same as the SEAT Ibiza 130 Sport/FR and Golf VR6 iirc)



Here is a comparrison between the std 288mm brakes and the 312mm and its clear why you cant just use the carriers on the old calipers.



Right back on with the job, remove the brake disc retaining screw and persuade the disc off with the correct toolage. Slacken off the 11mm bolt on the fluid line and nip it back up, this will make it eaiser to remove when the caliper isnt mounted to something solid. Remove the two 18mm carrier bolts and remove the entire caliper/carrier assembley. At this point leave the fluid line connected.



Now clean any rust up from the hub fce and fit the new 312mm brake discs, instantly looking more manly.



Next job is to fit the carrier back onto the hub with the 18mm bolts



Now fit the pads into the caplier and carrier and attatch the caliper to the carrier with the two 7mm allen key key sliders, also fit the anti rattle spring to the outside.



The fluid line can now be disconnected from the old redundant caliper and connected upto the new one. On this car I used the standard line, this does work fine. You can use the S3/TT line if required, it does give you a little more slack but is not required.



Bleeding the hydraulic system is now required, for this i'd recommend a pressure bleeder as it saves potential damage to the master cylinder and can make this a one man job.

Repeat for the other side, fit the wheel back on (tighten bolts to 120nm) a nd sit back and marvel at the glory of your new brakes



Now go steady for a few hundred miles, they may feel a bit odd until they are bedded in. The brake pedal may feel a little spongy until the pads have settled but it should be quite firm before to long.

As allways usual disclaimers, I accept no responsability for anyone following this 'guide' who may fit the brakes incorrectly. If your not sure then dont do it.

Very good.

Amazing how much more manly they are compared to 256mm brakes too.

I'd also recommend something for the painting process:

This assumes you've bought a full kit from say golfturbo

* Remove the hoses from the brakes
* Unclip the clips and remove the brake pads, and separate the carrier and calipers
* use the 3 day or 1 week masking tape to mask off the rubber
* There are a couple of small holes in the carrier & calipers, respectively. I used some strong nylon IIRC rope that I fed through those holes. Looped & knotted that so you have a loop through the two holes, with enough length to hang up on a nail (make sure you use a sufficiently long nail to hold the weight). In my case I hung it across a pipe I have running in my loft (horizontally).
* Using hammerite cleaner I liberally cleaned off the metal. I did this after cleaning off the brake fluid leaking out a bit. To apply it I just used a small brush, bought for the job as I couldnt be bothered to clean it This dripped a fair bit so I'd highly recommend some plastic sheeting (bin bag or something works well)
* The cleaner is pretty nasty stuff apparently so use a well-vented area (in my case the loft).
* Left it to dry up overnight, I'm sure you won't have to wait that long though.
* Using hammerite smooth green I then brushed the thing green, attempting to avoid the rubber and of course the location where the hoses attach.
* Leave to dry for 24 hours or thereabouts. Repeat the painting part if you like. It will probably last a bit longer then (I only did one coat though, as it looked good enough).

Annoyingly I forgot to take pics of this but it's not hard to imagine when you have the pics in Ross' guide above

[octav.ed]

yes 2 good guides there. personally i used blue hammerite cos mines not a vrs!

[WW_VRS]

Makes sense

[delroy]

Thanks for the guide Ross. Is it possible to have the link in the discussion thread changed to direct others here?

Top job !!!!!!!!!!

Now you've gone and muddled my decision. I was just going with upgraded pads and disks, but having seen those 312mm on there, I'm liking it a lot!!!!!!!!

[mr. hedgehog]

May be a daft Q, but where can i buy the green hammerite?

[delroy]

Any good DIY shop, that said my local B&Q didn't stock it, luckily homebase did!

[ric04vrs]

lummox , just a thought , would it not be a good idea to just undo the fluid hose whilst the caliper is still secure to the bracket and then nip it up so no fluid leaks , just might make it a bit easier when swapping the pipe across to the new caliper instead of possibly straining the pipe undoing a tight union bolt ,good guide though and the zimmerman discs i saw on fluffmeisters VRS looked superb , i'm seriously considering fitting some

Ric, good idea.

I'll be sure to post pics of those same Zimmermans fitted to mine later this week, just to tempt you even further

Fitting 312's, no problem, refitting standards I must admit a little muppetry was involved

Zimmermann 312mm Brakes

[mr. hedgehog]

I've got the Zimmermans waiting to go on - two weeks until they are fitted. i'll post a few pics when all painted up and fitted.

Again, another potentially dumb question, but what wheels are those in the pic - octavia? Can you tell i'm new to skodas?

[Lummox]

Check his signature, yes they are.

[dino21]

does anybody have some experience with this brakes??how much are they??
thakns a lot for some hepl

[Wardy]

Yes, loads of people have fitted these now. Do a search and you'll find lots of positive experiences on the fourm.

See GolfTurbo's thread in 'For Sale' for details of prices.

Both of these "how To" guides are excellent.... looking to up-grade my brakes after my remap in june..... I have no doubt these will prove a big help... Thanks
