Breaker 980 Report post Posted February 8, 2015 Just come back from 3200 K's of touring, starting to get a steering wheel wobble/ vibration under medium brakes. Looking for some ideas before I ask the 'experts' who get paid as they so often seem FOS. Brake pressure still good, had no 'events' for the brakes over the trip. Total Ks on car now 55000 only Ideas? Quote Share this post Link to post Share on other sites

handgrenade 189 Report post Posted February 8, 2015 Warped rotors usually you feel it in the brake pedal from my experience Quote Share this post Link to post Share on other sites
handgrenade 189 Report post Posted February 8, 2015 Could be alignment or wheel balance Quote Share this post Link to post Share on other sites
lord_jagganath 421 Report post Posted February 8, 2015 sounds like a tiny weight has been knocked off the wheel while touring. can and has happened. Quote Share this post Link to post Share on other sites
jeffbebe 1559 Report post Posted February 8, 2015 Do the wheels have hubcentric rings? That can also cause a wobble, though usually noticeable when not braking as well. Check the rotors first - if there's enough left on them a skim might sort your problem. Then check wheels are all balanced and alignment correct. Lastly, check front suspension, particularly upper control arms. Quote Share this post Link to post Share on other sites

Allanw 1071 Report post Posted February 9, 2015 control arms bushes,classic 5 series symptom.Woulda thought a bit low ks for that though hmmmmm... aja540i was replacing them about yearly I think, in his E39 - I think the were genuine he was using too (it usually is). Last set may have been whiteline poly bushes??? The stock ones didn't cope well anyway. Quote Share this post Link to post Share on other sites
Young Thrash Driver 1020 Report post Posted February 10, 2015 Before you go replacing things left right and centre- give the brakes a thrash. Find a nice quiet road and do 4 or 5 emergency stops. Then see what happens. My E39 had the symptoms that you are describing, and I cured it with this medicine. 1 Quote Share this post Link to post Share on other sites
