I just replaced the front pads and within days my 91 vert clunks and bangs when I apply the brakes and rattles noticeably at slow speeds. Just ordered new calipers for the front from mid america. Any thoughts????

Quote: easy fix thair are tabs on the pads bend to make them tier,and make sure the slide pins move back and forth easy. good luck

I use a little anti-seize on the pin. Works wonders, and won't break down from heat or exposure.

Here's a couple random thoughts.

It doesn't sound like a frozen caliper to me. Clunking noises are signs of something loose. I would check all the bolts on the calipers to make sure that there's no problem there.

Did you retorque the wheels after driving them? I have seen the same symptoms on a car that the wheels were starting to come loose after being taken off and not retorqued after driving.

We checked the wheels---- the biggest problem I see is the calipers are loose and easily rattled by hand when the brakes are not applied

it sounds like the pin has worn out. they get rutted near where the caliper meets the bracket.

A little bit of loose is fine, if it's too tight, that could effect braking performance, but too loose is bad.

Also, check the upper control arm bolts. They can work loose, and create that clunk you are talking about. 19mm IIRC.

I bought new pins and it had no impact or change I'll take a look at the upper control arm----I had some folks say that it could be the caliper mount brackets wearing out at the upper position requiring replacement of the brackets--GM no longer stocks the item

that's a good point, but if the brackets are worn out, check www.vette2vette.com or www.corvettesalvage.com, you should be able to get good used parts.

Another thought, if the metal has worn down, take them to a machine shop, where they can weld them up and bring them back to spec.
