Clumping noise from breaking 1988 Cougar

Hello how do you do hopefully you can help me figure out this problem and I'm sure other people may have experienced the same problem

So anyway when I put my foot on the break I hear this like clumping noise or when I'm in reverse and I put my foot on the break I hear the clumping noise again is only on the left side not on the right side

And it just drives me crazy sometimes when I go on a bump I hear it but not that often usually when I'm putting my foot on the brake to stop or if I really put a lot of brake pressure I hear this clumping noise


And when it was raining it rained a lot here the clumping noise went away I didn't hear it at all we had some really hard rains that came through and I didn't hear the clumping noise the whole time I was driving that day even a couple days afterwards

But then the clumping noise came back and I only hear it again I stressed this strongly when my foot is on the brake or stepping on the brake for stopping

Now let me tell you what I replace I replace the tie rod, wheel bearings   I replace the ball joint which it needed cuz there was a little play in that anyway

I replace the brake pad I replace the caliper the caliper pins so I don't know what else to replace I don't even know what's causing it I have a feeling it's the calibers but the calipers are new along with the brake pads so I'm at a loss as to what it could be maybe you can think of something or somebody who might know the answer to this?

Could be something going on with the struts or ABS ? Have you look at a 1988 Cougar Forum online for help ?

Chasing sounds is not fun. In addition to the struts, inspect your sway bar end links and sway bar bushings to make sure they are tight and not worn out. Inspect your transmission mount (these are known to separate).

Sorry for the stupid questions first.

Did you put new hardware on with the pads?

Pad hardware would be a good place to start.

With what you've described its something being loaded when you hit the brakes and it apparently doesn't matter in which direction. If you've isolated it to the front I would look at all the moving parts to the suspension and steering. Get under there with a pry bar and try to move things in different directions. It helps to have the car at ride height when doing this because sometimes at full droop the bushings don't load the same. I'd also double check the adjustment on your wheel bearing, they tend to loosen up quickly after being installed.
