Fox 3 Posted October 3, 2008 I'm having a bit of a problem trying to find out the cause of a wobble under braking on my car. First, I assumed it was a warped front disk, swapped both and still got the wobble. Then after using the handbrake only, I decided it was from the rear end, so swapped all four wheels with a mate and the problem disappeared completely! So its safe to say the rear wheel(s) were out of balance, so I got them checked, one was a mile out so I got it re done. Now I've put the old wheels back on, its worse than ever! Its fine driving at any speed, until you brake? Could it be a warped drum? The wheels are speedlines with new 195/50/15 continental tyres, my mates wheels are 175/50/14's form a 106 rallye Its really baffling me at the moment! Anyone?

Peetypug 5 Posted October 3, 2008 buckled alloy maybe? Share this post Link to post Share on other sites
Fox 3 Posted October 3, 2008 Could be, although they look true, no signs of impact, would that not be found when they balanced them? Share this post Link to post Share on other sites
Peetypug 5 Posted October 3, 2008 (edited) not sure mate, just trying to eliminate probable causes Edited October 3, 2008 by sorrentopete Share this post Link to post Share on other sites

Peetypug 5 Posted October 3, 2008 is it steering wheel wobble? can you feel it through the brake pedal? Share this post Link to post Share on other sites
Peetypug 5 Posted October 3, 2008 could be a tyre problem Share this post Link to post Share on other sites
Fox 3 Posted October 3, 2008 Good point! It can be felt through the brake pedal, feels a bit like ABS Share this post Link to post Share on other sites
Peetypug 5 Posted October 3, 2008 have you changed/repaired anything recently or around the time you first felt it? Share this post Link to post Share on other sites
dirtdog 4 Posted October 3, 2008 (edited) Fox, I have the same problem. I haven't changed the wheels around yet but I'm pretty sure one is buckled. I can feel it judder when i'm braking and when on the brake tester the rear passenger side moves up and down. Mechanic first told me oval drums, so I replaced those and it didn't make a diffrence. He then told me it'd be a bent stub axle, which I then found out wouldn't make it bounce/judder etc. Then I realised that the juddering came around about the time (and I can't be 100% sure)I had me wheels back from the powder coaters The car is SORN at the moment so I can't change the wheels around, I'd try to swap the wobbly side to the ok side, then take it for a drive and see if the wobbling/juddering whatever has changed sides. Personally I think i've got a dead wheel Edited October 3, 2008 by dirtdog Share this post Link to post Share on other sites

Personally I think i've got a dead wheel Bugger. I too think it happened around the time I got the wheels back from being powder coated, are your wheels a dead tight fit on the hub due to the increased thickness of the powder coating? I thought that may be affecting it so gave them a good brush out Share this post Link to post Share on other sites
dirtdog 4 Posted October 3, 2008 They fit like a glove. I put them on and then used the wheel nuts to pull each one on properly Share this post Link to post Share on other sites
