Brake Caliper Slide Shims

[K.N.94PSD]

I've noticed that since I replaced my front brake calipers with OEM Ford/Motorcraft remanufactured units a few years ago, I've been getting a clunk noise from the passenger side of the truck when the suspension cycles. I've examined that side of the truck and determined that there's a fair amount of slop (~1/16") between the caliper slides and caliper mounting bracket slides, causing the clunk. So, I'm guessing Ford's caliper reman contractor didn't check the dimensional specs of the caliper they remanned, and I ended up with the result.
I've heard that there's shims available in the aftermarket to correct this situation, but I haven't had any luck finding them. So, if anyone has any recommended part numbers or suppliers for the shims, please let me know.
Keep in mind that my truck is a 94, so its calipers use the older split steel and rubber slide pins; not the bolt, sleve, and boot type on the 95-up PSDs.

Thanks,
K.N.

I've never had that particular problem on mine (knock-on-wood). Have you tried new slide pins (I'm thinking you probably have)? Cheers!

Ah...the dreaded "clunk" from the left side near the front of the truck. This issue has plagued Ford truck drivers for years. There is no one particular item that causes it. Everything from frame rivets to loose fender mount bolts and everything in between...

Hopefully just installing shims will help you eliminate yours...but if not, do a search on here for "clunk" and begin the odyssey that many of the rest of us have been through to help eliminate one of the great mysteries of our time.

Thanks for the replies Patrick and Craig.

Patrick, I installed new Motorcraft pins when I replaced the calipers a few years ago. They still look good, but I suppose new pins could help.

Craig, luckily, I know where the clunk is coming from, the problem is finding the shims to correct the issue.

So, if anyone knows of a source for shims to correct the worn slides, it would really help.
