Title: Brake q
Post by: navmk4gti on 25 February 2012, 01:53
Been doing some reading up as im getting a wobble when i brake sharply.. How do i check the discs are warped? The discs are only year old but thought check them too.. Will be changing tracking rods and pads next week.. Had look at pads they dont actualy look that bad :undecided:

Also at high speed 90mph plus ( private road ofcourse :evil:) the steering shakes quite bad .. Iv had wheelS balanced and even got new tyres all around.. Would a knackered steering rack cause this or a warp disc  :undecided:

Play in steering rack or a warped disc both give the symptoms you describe, take your disc off and have it checked. Majority of cars I service, it's those using eBay grooved or drilled discs that warp.

Would this also be the same as an advisory on your MOT for 'brake imbalance' ? I got this advisory a month or so ago and they mechanic said the brakes probably just need a good clean out...

A good way of checking the brakes is to get a magnetic DTI and put on te wing and put the tip on the disc and the. Turn it and look out for the differential in measurement.

+2 thats if you have a dti or even know what one is.have them at work not cheap to buy a decent one though.also if you do this put somethnig under the magnet as might scrath paint taking it off.

DTI stands for "dial test Indictator" it is basically a dial on a rod with a magnetic base and it has a pointer that can move in and out and as it does the dial reads how far it has moved normally in thousandths of a inch and to .01mm etc

So you put it on your wing and put the pointer on your disc and rotate the outside of the dial so the poi ter is pointing to 0 and then spin your disc and watch move any movement on the dial.
They also used for measure the concentric it's of shafts in motors, turbos etc

You can't normally feel it as the "weave" could occurs over half a turn o the disc so unless you hole the Wing incredibly tight and have solid finger you won't be able to feel it  :laugh:

Dunno about dealer but have a look on places such as awesome, larkspeed and venom for performance pads dunno about own, tps maybe?
Title: Re: Brake q
Post by: navmk4gti on 25 February 2012, 16:01
awesome are getting close to being as crazy as stealers now .. will give tps a ring on monday then.. the front are 256mm and rear are 212mm is that right on a AGU?  :smiley:

Ok mate, yeah bits like that don't tend to be cheap from then but they are good or bits like ricirc valve etc
You mean disc size?
Are they not 288 front and 232 on the rear?
Title: Re: Brake q

sorry my bad it is 288 front 256 rear  :grin:

Well at least that makes two of us that have brake setups that don't warp  :cool:

that's some nice callipers and wheels you got there mate.

They won't warp as warping occurs from them gettin so hot they deform, and  it would take some good effort to get 340mm discs that hot haha
Title: Re: Brake q
Post by: rockmonkey69 on 25 February 2012, 17:43
Thanks! They do turn heads when I pull up for petrol, I'm sure you noticed this too  :wink: Two piece floating disks are much better at dissipating heat and allow for rapid expansion/contraction of the disk as it's separate from the mounting disk which allows for a change in size without constriction. If you notice the bolts all the way around the inner section of our yellowish disks they are actually two disks. This means you can use a different alloy on the friction disk from the mounting disk too which helps further with heat dissipation.

It's pretty cool, after any driving if I'm stationery you can hear crackling noises from the disk where it's contracting.
Title: Re: Brake q
Post by: navmk4gti on 25 February 2012, 17:44
they must have cost a bit  :smiley: so would vented disc reduce chance of warping i take it as they stay more cool

mintex, brembo

rear pads about £15-18
front pads about £23-27

i doubt the authenticy on the brembos tho  :undecided:

i can get full set from local shop for about £20 but they are a bag of sh!t  :grin:
Title: Re: Brake q
Post by: rockmonkey69 on 25 February 2012, 18:08
Don't think anyone using two piece disks look forward to replacing the disk, price for replacement friction disk ranges from £250-500 each disk.  :shocked:
But fortunately, I don't have to worry about mine for quite a while yet.

Yeah not exactly cheap but I think they are necessary for the power I want.

I don't actually know much about break pads but that price for Mintex seems about right but would expect been I ones to be more than that.

Yeah they arnt to cheap found some for about £212 but luckily mine have quite a bit of life left will probably last till I sell the car in a year or two.

what power you running golfyste

Not much at the mo think about 180, don't think I have a very good map as it only boost to about 10 psi then holds at 8psi but has defiantly been mapped by the previous owner. Lately got the the intercooler on, and just bought a k04-001, got bigger injectors to put on and walbro pump, and a few other bits then off to r tech hoping for about 260ish hP and 270-280 ftlb  :grin:

Thanks buddy, I always pick my competition on the track by their brake setups lol too often brakes are under-rated, but I'm sure you've found out before they are a life saver if you misjudged an entry speed to a corner.

288mm rear sounds good, I thought about upgrading the rear on mine as I still have the standard 232mm rear, but I haven't decided what setup to go for yet. I like the looks of the dual caliper rear setups but I still have a large shopping list before I look at the rear brakes. Let me know how the braking balance is after you upgrade your rear setup  :wink:
