Default Caliper knocking sound?

Hello guys,

1991 ZR-1

Since I've got the car (2015), I can hear a knocking sound on my rear left. I looked at every single thing, everything is tight.

Except for one of the calipers bolt. When the car is stopped, there is some play in the caliper. Mechanic told me it could very well be my problem.

What do you guys think? Did it ever happen to you?

Why not just tighten the loose caliper bolt and see if the knocking sound goes away.

I had a caliper rattle in my left front and ended up being the caliper pins...Autozone had them in stock for about 6 bucks and it took care of the rattle. I'm not sure if that's your problem but it was a cheap fix.


Steve,

Try replacing the caliper pad pins
