BRAKE SHUDDER ISSUE

[boost69]

I have had DBA 4000 slotted rotors and Bendix Ultimates on the front for about two weeks now and I am getting brake shudder when braking hard at HWY speeds...its quite annoying actually as I was quite concious of running everything in properly etc...and I still got the shudders...not sure what I should do now...

Maybe try Race Brakes RB24 pads. I have DBA 4000 slotted rotors with RB24 pads and not had any issues now for over 3 months now. From what Race Brakes told me - pads can make a bit of difference. The pads were pretty cheap - here's my link for more info.

Not sure how many of you guys have seen this article before, but I'm willing to bet that 90% of the brake shudder complaints are due to the issues mentioned in this article:

Great article TCR

The brake shudder on my 2005 XR6T is such a pain in the ass to the point it will almost shake the wheel out of my hands.

I'm going to try replacing 1 thing at a time to try & figure out exactly what the culprit is.It does feel like a warped disc but I've had a good look over them all & can't see any evidence or any runout at all with the dial indicator

Will let you know what I find

Hi RXENG, why don't you just jettison the Ford front stock rotors (which I am told are PBRs) and upgrade to DBA 4000 slotted rotors with Race Brake RB24s? I did that almost a year ago because of massive brake shudder and never looked back

I don't know if its a testimony to putting my money where my mouth is, but I just wanted to continue the story which I started about a year ago here in post #1321 where I talked about my experiences doing my front brakes. Well, this morning, I had my rear brakes done as well - farrrkin smick looking too I've still got to run them in - probably take about 200km according to Roger there, but so far they are good.

BA Rear DBA 4000 slotted rotors part numbers DBA4505SL and DBA4505SR ($166 each)

Race Brake RB24 pads part numbers DB1086RB24 ($88 for pair)

Supply and fitting is extra but Race Brakes can do that while you wait (only took me about 1 hour).

By the way, DBA 4000 slotted rotors to suit BA front brakes (to get rid of brake shudder) are part numbers DBA4504SL and DBA4504SR ($166 each as well - there's been a price rise since I did them last year).

Just quote that you are from FordXR6Turbo to get the special prices

Hope this helps you guys and feel free to ask me anything about my experience with the brake setup I got

Yes Rotors can get run out "warped discs” which are felt under braking, however due to the set up of both the BA & BF’s front lower control arms and your driving style the bushes throughout the control arms get severely worn around 60 - 70 K's. Tell tale signs of the bushes being worn are slight “wheel balance needed feeling when driving” and of course the whole warped disc brake shudder feel on braking. If you replace your rotors and this problem still is there you’ll need to got down to your local suspension workshop and get a quote on replacing the bushes. Also while your there ask about getting your diff bush checked as well cause that bush cops a beating deluxe!

Had factory brake rotors machined at 50 000, at 100000 the shudder was so bad I replaced them with dba slotted rotors and bendix premiums, not a shudder since. And huge improvement in brake stopping.

I think I discovered what happens when you have extreme brake shudder:

Notice anything missing??? the car had slightly spongy brakes and a massive loud rattle.

heard a clunk bang and this missus said "what the hell was that"

:censored: :censored:

So is it the whole bolt come out or has it sheared the head off. I think most peoples shudder isnt related to a missing part.
