this may answer some questions Australian Ford Forums - One reason why the BA shudder keeps coming back ! reason why the BA shudder keeps coming back ! G'day , after an exhaustive day with the Nolethane gurus as well as Geoff Murray from Redranger and Steve Borg from TRW Australia, I now have a much better understanding of my car (BA) the BF/FG and the VE front and rear geometry and the factory suspension shortcomings... I started a thread how to change out the hydraulic castor bushes here www.fordforums.com.au/showthread.php?t=11306516 Now one thing I couldn't explain was why they stopped my brake shudder , my best information out of today is the bush when it fails moves around a heck of a lot and over time even though the wheel is mounted to the rotor and then onto the hub it creates wear points on the face of the rotor called "DTV" Disc Thickness Variation ..... Oh well we just give the rotor a skim and no more problems Right ? Until next time.... I machined my rotors 5 x times before I purchased slotted rotors and the shudder came back ! It became so random and sooo annoying I wouldn't let my girlfriend drive it anywhere.. I changed the front bushes and the shudder dissapeared straight away.... I couldn't explain to anyone why the bushes created shudder if someone had just had their rotors machined and the situation appeared fixed .... Only for 5000-7000kms or so only to return .. Fact , if you replace your front bushes as well as fresh rotors/pads and wirebrush the mating service on the hub you will NEVER get that 'SHUDDER' again..... Ford went to great lengths to explain to us via tech bulletins , how to line up the yellow stud with the date stamp on the rotor / how to torque the wheel nuts correctly ( NEVER use a rattle gun ) so as not to warp the rotor/ and most importantly to keep the mating surfaces free of rust/debris to insure perfect roundness for pad contact... If you follow the correct procedure for maching the rotor and the problem comes back , then it is time to look elsewhere... I have finally fixed mine "Hallelujah". I know I have probably forgotten something because my head is ready to explode with information ... But I hope this sheds some light on our front end , these are essentially Taxis and absorb everything we throw at them but the FPV's are wearing these bushes out much faster and the Brembo's seem to mask the problem because their quality of manufacturing is so high they dont produce DTV very readily .. Thanks for reading and please change your Hydraulic Castor Bushes.. The difference in having precise control of your front end is amazing ..cheers. Daz..x..
