Ok when you brake in my 93 Civic EX the driver side front brake makes a clunking noise. Just 1 thud and thats it. Brake pedal still feels good and car stops great. What could be the problem.

Oh yea it's non-ABS

 

Could be a few different things pertaining to your suspension on that corner. I would first check to see if it is simply the pad rocking back and forth in the caliper. This happens sometimes when the little metal shims that go on either end of the pads fall out or were not installed properly.

 

Thanks I'll check to see if it's still there. I changed the pads about 6 months ago. It started to clunk maybe a month and a half ago maybe 2 months.

 

i would check the lower control arm bushings

 

Sounds to me like suspension rather than brake issue.

Like he said, check the LCA bushings. It's a 93, they should probably be replaced anyway.
