Loud Creaking Noise When Braking

[lex28]

Hi guys..

for a quite a while now, on and off, I've put having a loud creaking sound from the front driver side brakes. At low and high speeds, smooth and bumpy roads and also when brake pedal is only slightly touched I get a loud creaking sound until at a stop. 

Been to Lexus Leic who after having car for 3 hours only greased caliper pins and a general check on other components who come to the conclusion it's more than likely top mount? 

I have changed pads few months ago and discs last year. Caliper pins have been checked 4 times in 6 months and greased. 

Lexus want over £300 for top mount part and labour and have said they will work with me IF they have mis diagonised the problem. 

Is there any suitable independent garages in the midlands anyone can recommend as  personally believe lexus leic don't have the slightlest clue!

Same here.  Changed my ball joints, but it still does it slightly.  Will change the links next as they are cheap and seemed quite "loose"

Brake caliper sliding pin has a rubber bush which deteriorates and causes too much free play and the groaning noise - weird.
