I bought a 2005 530D sport privately a few months ago,when i wen't to look at i noticed that it was fitted with brand new discs and pads on the front.The seller stated that they were changed by the garage he bought it from after they fitted pattern parts that warped,these were replaced with genuine BMW parts to cure the warping issue,i test drove the car and no judder was present.
I then began to notice the car juddering on braking,mostly sub 30mph.I did a bit of research and read that the E39 can suffer with brake judder if the compliance bushes are shot,my car has 88000 miles on it so thought that could well be the cause of my problems.
So after a day lay on the drive i have fitted 2 new genuine compliance bushes,the ball joints on the other end of the track control arm felt fine,nice and firm.
All back together,no bloody different
I'm now thinking that i shouldn't have presumed because the discs were new they couldn't be the problem.Will do what i should have done in the first place and check run out.
If that proves to be ok where do you think the next most likely place to check would be? Topmounts?
I'm all ears for suggestions.
To make matters worse,while struggling to un do the ball joint my star bit snapped resulting in me smashing my 1/2" ratchet drive into my forehead leaving me with a decent cut and big bloody lump
Time for a beer.
