tremendous vibration under braking
« on: 13 July 2011, 06:37:20 PM »
hello all from the old forum. 

I'm getting tremendous vibration under braking, now both front discs are showing areas of rubbing and the sterring wheel under braking is all over the place, tracking is apparantley bop on.  The discs are less than 12 months old EBC Ultimax with Red pads.

I'm thinking this could be the anti roll bar as it took a beating some time ago, what are your thoughts? 

I'm gona whip the fronts off either later tonight or tomorrow and check the discs for any any sign of warping which I reckon is unlikely but its worth a check.

Check the EBC bits carefully.  I've seen some of their discs that have cracked with use.  And I had some Greenstuff pads that fell apart - suddenly!  But my experience was a while ago now.

Discs can warp even when new - check the run-out. I'm on my third set with the Pug - and I reckon the reason is not the discs themselves at fault,  but poorly seated/worn hub assembly :-\

Does sound like disc warp to me too from the description  ::)

got some front pagid discs and pads today from ECP for £95, the ultimax discs were £168 alone...  Sorted the problem.

The EBC Ultimax's had high spots all over them approx 1" apart up and down the height of the disc, annoyed concidering the cost of them, I'd like to get them turned as they've only been on for 10 months.  When I say high spots I'm talking get the micrometer out, in all honesty I'm super pissed and refuse to throw nearly 170 quids with of disc in the bin.

Only thing to do now is sort out my 2 year old vibration / knocking coming up through steering wheel from somewhere.
