Hey peeps....thought I would throw this out there in case anyone knows or has experienced similar scenario

Basically; my shudder has come back.

I had new rda shi*y rotors, bremtec pads, goodridge braided lines and rebuilt calipers all round.

Had no shudder for around 5000kms and then it came back.

At first it was only present during super heavy brake application...now it can be present in anything above 50kmh. Obviously at 90kmh+ it is there with light brake application....under this speed its only present in medium to hard application

When speaking to RDA...their "expert team" stated its either a suspension or steering component causing premature wear...and if I changed rotors again or even machined...they would warp after 5000kms again..therefore need to sort out issue first before doing anything

Read that lower control arm bushes can cause shudder? Going to Pedders next week to see if their machines/processes can point anything out? Every shop I been to says "bushes look fine"...but yeah

Any help would be good.

Other issues/symptoms that could be related or possibly not include:

1) weird clunking noise from front drivers wheel area (only when going over chit roads/brick paved roads

2) intermittent vibrations; usually steering wheel and speeds above 70kmh (had tailshaft replaced but ford said maybe need readustment/rebalance)

3) slight play in steering wheel - approx 5-10mm

4) weird wobble (from left to right) of whole car...only in peak hr traffic on mitchell freeway between 15-30kmh and only when accelerating/backing off I.e. bumper 2 bumper traffic

Had wheel allignments, balances, tailshaft replaced, sliding pins of calipers regreased, wheel hubs cleaned/greased...

Car is a 2008 FG XR6T, sedan, auto, 116,000kms

Thanks for any opinions...hoping someone has a clue :)

Cheers!

Don't drive on the Mitchell freeway. Problem solved

But seriously is the shudder / vibration coming through the car or the steering wheel

We have a BA wagon bought at 95000km. It started to shudder when braking, shortly after we got it.

Ford machined the disks under warranty just before the warranty ran out, but the suffer came back fairly fairly quickly.

I bought some ADB disks and ADB "performance" pads fairly cheap through eBay and never had another problem.

The car has now done 215000km and I just changed the pads. I think they lasted amazingly well.

I also like the way they work.

We do not give the brakes a hard time on this car, but brake shudder

A. Happened with the original disks

B. Came back quite quickly after machining the original disks

C. Was permanently fixed by changing disks

Based on that I would suspect that the disks should be replaced.

^^^Thanks for the input mate!

The thing is I replaced OEM rotors with the RDA slotted/dimpled...I would have thought they would be better than ADB setup cause slightly more expensive?

Interesting you have had good experiences with that brand...goes to show the cheaper stuff isnt too bad sometimes

But will be going DBA just cause.

Don't drive on the Mitchell freeway. Problem solved

But seriously is the shudder / vibration coming through the car or the steering wheel

Lol...no mitchell fwy is not an option..sure the "wobble" might stop but the other symptoms are still there

The shudder I.e. braking. Is through whole car and steering wheel

The vibration is mainly through steering wheel/pedals...its intermittent and usually only when coasting I.e. under 2000rpm. This could be just the shocks/springs going over some slightly rough roads (apparently my car had f6 suspension and ford dude said slightly stiffer springs? - couldn't get him to notice it during small test drive)

But the shudder is what sucks the most. FML

Just for the record, I have RDA's on my ute and don't rate them at all

Shudder like hell at any moderately hard braking, though fine around town

More recently had warped rotors on the G6ET - family rig - and replaced them with DBA 4000s

Swear by them

How can you put up with them shuddering like hell? LOL

Mine is worst when temp is warm; say after 20mins of driving and using the brakes normally. Then when you hit the freeway and even soft braking makes the whole car violently shake! It sucks cause no hooning around either....like overtaking someone then having to brake pretty much straight away (cause another retard ahead) and then violent shudder :(

But will be going DBA once I have some spare cash. I am tempted to go T2's for front cause its $120 cheaper....but I have to learn to do it once, do it right....so will go T3's at the front :)

DBA_4000_Series_XS_Cross_Drilled_Brake_R

^^^ I have a set of DBA cross drilled/slotted for the rears (got it really cheap of fleabay)....so was thinking of painting the hat area of rotor to black; because they come with yellow hats and yellow inside the venting part of disc.

On a side note; does anyone know if it is fine to just use engine enamel (high temp) spray can paint on the rotors and would I need to buy high temp primer as well or should be fine just painting over the DBA yellow paint? I will just do them gloss black I rekon.....unless of coarse I shouldn't risk it and just put up with grey/charcoal coloured hats in the front (T3) and then yellow hats in the rear (XS) I.e. will the extra layer of paint will somehow affect something?

116,000kms Ralph.

Cant find that term on Nolathane website? Which ones please :)

If this was the problem; would it be apparent/show up when I take it to Pedders to do their little "Test Lane Plus" thing?
