I have a 91 2WD with 310K miles. Whenever I make a brake application I get a clunk. Someone thought it might be body flex? You can make it sound off repeatedly by just applying the brakes moderately. With the passenger window down its very noticeable running along a curb. I have to believe its a caliper shifting on the slides. Thinking about replacing the right front caliper and see what happens. If the spindle bracket is worn..is this part replaceable?
thanks.

 

I could be missing the anti rattle clips and the pads are moving in the bracket.
