AU99,
i got the new tyres put on last weekend and balanced. I also got wheel alignment after. I saw the guy put the wheels on the balancer but i didn not pay much attention. Guy did the alignment at another shop and it was all good pretty much apart from the rear being 1.2 mm out. I will swap and put on my dads ED fairmont 15" rims on when i get a chance and see if that eliminated the issue. Trial and error is the key i guess. cheers |

all this time and money.
it would of been better to machine your discs in the 1st place and be done with it. if it still shudders after that you may have some loose suspension/steering/brearings |

dont try putting ED or 15" wheels on
ED wheels will not fit and 15s will not clear the brakes i also had this problem when i purchased my BA XR6 and i know what an annoyance it can be. i purchased DBA 4000 series Slotted Rotors for the fronts and DBA street series Slotted Rotors for the rear all with Bendix General CT pads (this was the same setup i chose for dads BF XR6 3 years ago and he had 3 years of 0 brake issues) i paid my local mechanic $50 to whack it all on and ive had 0 shudder since. sounds like a buckled rim to me, i hit a pothole coming home from work last week and buckled a rim its in getting repaired at the moment |

One other thing it COULD be, the front Hubs, when worn they can cause shuddering.

hi all,
just thought id post my solution, incase someone does a search in the future they will have a possible cause. I started scratching my head and considering maybe my brand new front rotors were not machined properly from the factory or the new bendix pads were not good. I machined my front rotors replaced the brake pads with Australian Disc Brakes Performance (which is similar compound as bendix) except it cost half the price and i no longer have brake shudder. Problem solved...faulty front pads or disc rotor. |

Hey guys, I would check the booster.
BA's had a problem with booster rod tolerance causing the brakes to apply at 80-100kmh. A reco booster will fix this. Cheers Stu |

Hi ronsta86, the painter at my work had a similar problem and his calipers had a rattle as well. After a lot of hassling the local Ford dealer, they finally changed over one caliper and inserted a sleeve kit into the hole where the mounting bolts go though the caliper to the stub. It is cured at the moment but he has spoken to a few other BA owners and they have the same issue. It might help, just get a ruber mallet and tap the calipers. If they rattle it might be the worn bolts.

Cheers Stu Sounds exactly like my problem. Driving along in that speed range and no brakes applied - get the wobbles. Very annoying. I have the FTG upgraded brakes up front - so I know/hope they are not warped. In fact I know they aren't because Ford adjusted it but now it is back! It was good for a while after they did it. So how much is a reco booster worth and how difficult to fit?

The booster is pretty staight forward to change, as long as you dont mind crawling under the dash.
Best bet would be to talk to your local bake shop, i work in one in sydney, i might be able to cost one up for you. Cheers |
