Brake Upgrade

[EMZ R33]

Hi all. Have a prob...or two.

Under heavy breaking in having a great deal of "shudder" at the front end. The dash, trans and s/wheel all shakes like hell esp when im breaking from 80kms or above.

Wondering if this is due to small / inadequate breaks and/or rotor setup??

I know it might sound stupid but if i were to go for bigger rotors and pads do i need to change any of the standard setup at the front end? Also if anyone has upgraded their N/A's rotors and pads what are the costs involved??

Any help would be awesome, i have taken heaps of pics of my current setup as i just changed my front suspension, if they will help please let me know and ill post em'

sounds like warped rotors or something. get them machined

Gday mate,

I had the same prob, pretty much sounds like your rotors need to be machined, if there is enough meat left on them, this normally happens after a while under heavy braking, not due to inadequate brakes or rotors, this is very cheap to fix up btw...

I am in the process of updating my brakes and rotors. I bought some turbo brakes for a couple of hundred I think...like 200 ... I need some dba slotted rotors ..couple hundred and some pads...80? 100? 150?, its not too expensive all over.

it is a good upgrade to do, but especially because I have converted the car to turbo and am still on stock n/a brakes.

hope this helps a little.

Do you by any chance have the habit of leaving your foot on the brake pedal when stationary, at a set of lights or an intersection etc??

If so, you may have suffered "pad transference" where a small amount of pad material literally transfers to the disc surface, causing a high spot & a similar feeling to a warped disc. Get in the habit of NEVER sitting with any pressure on the brake pedal whilst the vehicle is stationary, use the handbrake instead if you have to. To fix, do a handful of hard stops (without coming to a halt) & you should wear the high-spots down IF it's a buildup prob. If they are indeed warped, machining is the only real fix.

To stop it happening again , try being off the pedal alltogether even before the vehicle comes to a stop. Sounds stupid maybe, but I'm talking within a few wheel rotations, not from speed etc

Thanks guys for the replyies.

I def dont sit on the brakes at the lights. Although my car is an auto i use the gears (sometimes) and always sit in neutral at the lights or when stationary.

Here is a pic of the driver side rotor....what do you guys think??

And another view

(worth machining or.....????)

So where i can go to get the disc/rotors machined...........local car tuner (ultra tune, midas, etc etc or.....?)

Also ppl, price wise New rotors Vs. machining them???

Again thanks guys for the advise!

lol, funny mate... they look as smooth as a baby's bumb... no way to really be able to see from a pic..

you could take them to almost any automotive mechanic/tuner and they will know the places to take them to be machined....

if you want a rough idea of how much for some rotors have a look at this group buy...

I actually spoke to rsd7 for a set of slotted non turbo rotors and he quoted me

"7691S $280 front pairs, 7692S $275 rear pairs, all delivered"... so looking at about $555 delivered

hope this helps... btw... gettting the rotors machined is cheap as chips...

Thanks a heap for the info Adam!

Ive sent a pm to rsd7 re front rotors and awaiting a response!

Also ive spoken to superchap auto (via their net sales rep) and they have quoted me:

dba 953 $129.99 ea +freight, dba 953sl/ sr $ 179.99ea +freight and dba 953x $236.36 + freight

Not bad if your just after relacement rotors, i think they are standard but thats a good price i think!

Kind regards, Evan

go buy seom turbo brakes......aswell maks a lot of difference and u should be able to pick them up second hand for cheap

[WYTSKY]

happy to help mate,

good to know that the local supercheap stores also cater for us if neccessary. also... while ur at it check ur pads if they need doing to....from memory they can't be any thinner then 8mm-9mm I believe.

I can't remember what brands are good but don't be suckered into the first ones you see that say they are great for stopping etc etc... i've found ive gotten alot of brake dust and screeches with those types.... do a little research on them... can't hurt

Cheers,

Adam

Hi all, just to keep people in the know, i took my ride to midas (glenelg), who continue to service my car awesomely, machined my front rotors and all is well now. Great feel on the pedal and no shudder anymore.

Thanks for the advice people.
