? Why this brake sound?
I have noticed that my brakes make a slapping/clapping sound when they are applied. Sounds like the pads are hitting the disks.
Is this normal?
I know some other cars have springs that pull the pads away from the disk, under tension. Why dosen't chevy do this on the vette?
Seems to me (after changing the brake pads) all the pads do is sit on the caliber (not locked in) and slide with no means of retracting off the disk after the brakes are released.
Any thoughts??

I am not aware of any brands of vehicles that pull the pads away from the rotors after braking. You don't want that to happen because it just takes more time to get the brakes applied when you need them. It also helps keep the rotor surfaces free of debris. As I recall back inte "old days" this was done with drum brakes because they wore by centrifugal force. This isn't the case with disks.

BTW, there are no springs that retract the piston into the caliper. The o-rings that seal the pistons are actually what retract the piston a few thousandths when you take your foot off the brake pedal.
Pull your wheels off and check out your pads.

We have a little Geo and the disk brakes have a spring type clip that pulls the pads from the disk. Have 150,000 miles on the car and never had a problem with the brakes, just routine pad changes.
Seems like a good system to me.
On my Tahoe ( and other chevy trucks) the pads clip onto the piston. This works well too.
So why does the corvette pads just sit there? Not held in place?

The pads are held in postion by 3 springs clips on the edges and the top of the pad.
The caliper, itself, "floats" on 2 pins so everything is always centered when the brakes are applied.

I know now what you are talking about with the "spring clips".
Cleaned then with a wire brush at the last pad change.
But they don't seem to be holding my pad to any real degree.
In other words the pads can easily slip/fall out if it was not for the rotors.
Should I get replacement clips or bend these a little to make better contact with the pad tabs?
