[urq] knocking sound under braking

[Johan H]

lately I have noticed a knocking sound almost every time I apply the brakes 
softly, this knocking sound also appears sometimes when I open the throttle.

The sound comes from the front left. At first I actually thought it was a 
loose brake caliper. Today I had a look att the caliper, but the bolts were 
tight... then I noticed the subframe bushing; the bolt and the metal "cup" 
that presses the rubber bushing towards the subframe was some 2cm off the 
rubber bushing itself. I compared the subframe bushing with one at the rear, 
and there the metal cup just touched the rubber itself...

Question; should I just tighten the bolt? and how much should I tighten the 
it? Or should I change the whole rubber bushing. The bushing itself seemed 
to be in good condition and is changed 40 000km ago. I suppose this makes 
the knocking sound, any thoughts?

Also worth mentioning is that the brakes pull to the right when I press the 
pedal fast and hard. If I press the pedal progressively then the car brakes 
perfectly in a straight line.

Has anyone had the same sort of experience?
