Skyline Braking Issue

[Ben C34]

So change disc then only ?

Would 15 mm give any noticeable improvement?

That won't work..

How would a bigger disc fit?

Have you looked at how brakes work?

[stranger12]

yep, thought i add some type of spacers or change caliper and disc

is it worth it ? does 15mm makes a big difference ?

also the link between subframe and front cross member which has a big rubber bush in it seems as it is leaking grease or oil, could it be that ?

I am trying to find a picture so can share it .

here is the pic of the bush

Yes thats the radius rod bush you have been told about, and looks like you have oil dripping around it as well. Check for leaks. Oil will soften and degrade rubber making any replacement bushes bad again soon.

[stranger12]

no oil dripping on it from anywhere.

it seems the rocker cover is leaking but that is far back .

do the bushes have some sort of grease or oil in them or someone has put oil on to stop it squeeking ( previous owner)

"Radius rods typically are mounted ahead of the wheel. In that position they resist dive under braking forces and wheel hop underacceleration."

could be that then

many thanks

by the way is dba a good brand? In UK i am seeing ebc and mtec for brake discs and they are £200 for a pair of front discs compared to £100 for dba

One thing that we see on brakes thats been overlooked is the wheel hubs being warped.

Tyre shops love using rattle guns and over tightening wheel nuts, this warps the hub which in turn means the rotor sitting over it will have runout.

And one other thing is disc thickness variation, some pads agrivate this issue, once the rotor is scolloped its hard to measure with a dial indicator, only a light skim brings back the rotors.

Everything else said previously concerning other causes it pretty spot on.....

Also sticking calipers are a major source of warped rotors, push back the pistons, make sure none are hard to push back, any that are are overheating the rotor on one side.

[Ben C34]

Where do you plan "adding a spacer" to fit the bigger rotor?

It won't work.

[stranger12]

ok so that is now off my head as not willing to spend 1k to buy gtr calipers.

will leave it as it is . would you think dba is any good or get ebc ?

ebc is almost double

[Jordy32]

You don't need GTR Calipers and rotors, just get new rotors and pads and give the brakes a bleed.

You're over complicating this

[stranger12]

any view on the discs?

I want to changed them to standard discs again and dba which is Australian made I think is only £100 for a pair where as EBC and motec is almost £200.

is DBA any good for street and occasional track use?

[GTRPSI]

DBA is not Australian made, its made in China, its a Australian company, just like RDA..

[stranger12]

so any good for forget it and get ebc ?

[GTSBoy]

They're fine. DBA brakes, that is. Perhaps not as great as they were before getting made in the shade of the Great Wall, but still fine

[GTRPSI]

We have run both DBA and RDA rotors on or GTR and S2000, not a problem.

EBC in Reds are rated to 650 degrees and very gentle on the rotors and low dust.

EBC Yellows are a little harsher on the disc, rated to 900 degrees and dust up heaps.

My everyday daily cars run the EBC Redstuff (FG Turbo ute and Mrs Falcon), GTR and S2000 is on Yellows as they get pushed hard and need a bit more temp rating for late braking etc.

EBC green are shit though.
