tt/s3 brakes on cupra turbo under standard 16's?

[m0rk]

I don't think you've made a good connection 1st time & stripped it

you don't want to use PTFE tape, it should be a good thread.

The dimensions are all the same - but you may have needed to modify your soft hose to clear the chassis? there was a little dimple I had to remove on my hose (it was a long time ago)

 

[exsaxoboy!]

Well the thread on the hard union is fine, and ive tried the off side calliper too and this was the same, loose! Ill strip it down again when i have time, im going to check the thread pitch tomoz at work.Soft line clear chassis and strut fine, no probs there.

Im presuming the hard lines on a mk2 come from the top left hand side, the same as on a mk3?

 

[m0rk]

yeah - they're the same.

don't drive it until you're 110% sure though.

 

[exsaxoboy!]

lol, nah i wouldnt mate, wouldnt want the hoses blowing off !

Now that would be a problem!

 

[claudefrog]

what did you do about your discs??

im finding it tough finding 5 hole'd discs.

pics would be great !!!

 

[exsaxoboy!]

I just re drilled the multi stud disks. It ends up you use 2 standard holes allready drilled, and you have to drilll another 2 holes to get the 4*100 pattern. The two holes do fall into the other holes, but theres more than enougth thickness in my opinion to suport the disk. Is someone wants to hosts some pics for me ill put them up, because non of my pics seem to load.

 

[exsaxoboy!]

sorted out a photo bucket acount some pics........

umm.. i had my calipers machined, and drilled 2 extra holes in the multi hole'd discs... but not much sure on trusting them. as its really 3 holes in 1 and the other 2 std ones are fine i agree.


hummm.. wonder if i could find someone who could weld cast properly heating it up slowly and letting it cool slowly....


let us know how you get on.. im very very interested still

 

[exsaxoboy!]

Well on brakes i wouldnt reccomend anyone doing any thing there not sure about! but im going to use them because i can see theres no way the bolts will push througth into the other 2 holes.

If you really are worried about the holes you could get a blank machined up to sit in the holes either side, with a raduis machined in to let the bolt througth to the hub. Bit hard to explain with out a diagram. 5 stud disks shouldnt be to hard to come across, just ring round all the major tuning companys and someone will have some im sure, or go the dealers.

Now ive still gotta get round the hose issue..............................hmmmm!

I'm gettin my disks made up, either have them machined up or get bells made for them to match. Wont need to machine the carriers or drill disks.

You've got nothing to worry about on that front, they'll be fine as they is

 

[claudefrog]

excellent.. cheers Stu!

will give them a try.. if I die.. nice knowing ya all

 

[exsaxoboy!]

lol, if you look at it at from an engineers view, you would need a lot more presure than you will create braking, to rip througth the two solid holes that are allready drilled.

Off subject, i went to the dealers today to buy an electirc window switch and an interior door handle. total price 45 quid..... can u beleive it! robbin gits!

 

[exsaxoboy!]

Now all fitted

Finally after much much hassle the brakes are on. I did have a few problems along the way thougth!

Firstly, machining the callipers. I worked out from what m0rk said and my rougth measurements that 4 mm need to be machined off the inside of the calliper carrier, to acheive the correct offset. This was wrong. After trial fitting i found it was 6mm in total that needed to come off, as at 4mm the outside calliper rubbed on my brand new disk! as there wasnt enougth movement on the sliders to centralize the callipers.

Then the hoses. Originals tt hoses the thread was to loose on the thead, althougth ive been told by a local vw specialist that they should fit, and on here. i was then told to use mk3 vr6 hoses, which again i had exactly the same problem. In the end i used the cupra braided hoses, and althougth the fiment is banjo type on the tt calipers, it screwed in nice and tight!

So there we go nice improvement so far, althougth the pads are not bedded in properly yet. They seem to bite a lot harder and sooner than stock brakes anyway.

interesting that you needed to take so much off

4mm had mine sat bang in the middle of the carrier! Same for F2-Stu too (and he did his knowing 'some' had to come off, but measured it too.

Are you using 'normal' pads? you'll find they do work very well. less grabby than brembo's - but I found them more effective driving back to back

 

[exsaxoboy!]

using standard road pads for now, if they need changing for uprated ill change them in the future. At 4mm the carrier scored the disk, 6mm put the disk bang on central.

Still cant work out why vr6 or tt hoses wont fit mine, all i can imagine is the fitting onto the hard line must of been changed.

I was also suprised the calliper fitting off my braided hoses fitted the banjo fitting, but it does! if only i tries that first with out spending 36 quid on hoses lol.

Oh well its all fun and games modding cars!\

By the way the dodgy 17's are going. Back to 16's for me.

 

[m0rk]

Putting race pads in has made them comedy brakes - they're rediculous when hot. I may yet return to std pads for 'most' of the time though

 

[exsaxoboy!]

As in there just to grippy! to be honest i dont get on the track that much so stadard pads should be ok. But its nice to have the power there in the brakes when its needed, especially with more ponys. I can never understand why more people dont look into uprating the whole brake setup, as in my eyes its a very important mod with more power.

I too had to take off 6mm but dare'nt take off any more off, its like a 1.5mm off centre

 

[exsaxoboy!]

at 6mm, mines slap bang in the middle. still plenty of metal there to suport. I nearly bought a set of seat sport callipers with disks and pads... full set up. only wanted 300 quid too
