brake caliper question

OK. Here's one for you all. <G>
I have one bad disc caliper. It wore one pad down on that side in under 50 miles.
Am I supposed to replace just one caliper, or both, to do this right?
TIA

I'd do just the one. However, you'd better do a thorough examine of the rotor. To have gone through a pad in that distance it's probably toast. Are you sure it's a bad caliper and not some foreign material blocking the return flow of brake fluid? Or rusted caliper pins?

I know the disc is toast. The wife told me she heard a grinding, and after checking both rotors, I went out and got rotors and pads for the front. <G>
While changing all that, I found that I can't push the actuator back into the caliper using the small block of wood and C clamp trick. I used a bigger block of wood and tried to get the actuator to move out some. Well, it is securely frozen now apparently...
With the pads out, I reassembled the whole thing and am able to slide the good pad side in and out, so I know the pins are OK...
Thanks for the suggestions though...

You do realize that the rear disc calipers on these cars SCREW in, right :)?
You need a special tool to drive the piston back into the bore. Autozone or any retailer will rent it for free to you.
If not, Sears or any parts store will have it.
Throw both calipers out and get two new reubilds. A-1 Cardone or ARC do most of the rebuilds you see out there.

The C clamp/board trick won't work on the fronts?

Planning to do just that. <G>
Thanks

Fronts yes, I thought it was rears for some reason you were working on?
As noted, change both flex lines. Raybestos, Wagner, and others supply these to parts stores and have them in stock. About 15 bones a side.

That would be very rare in a GM caliper. Did you open the bleeder screw while trying to push the piston back? Everyone should get into the habit. It keeps debris that accumulates at the bottom of the brake system from getting push up into more sensative parts like the master cylinder, or worse the antilock controller.
Most likely the hose is collasped.

How exactly is that rare in a GM caliper? Happens ALL the time.

Both. You always want to do anything to do with brakes in pairs by axle.

Thanks, FBR. That's what I thought, but I figured it would be better to check. <G>

Check your flex lines, I had one colapse internally and it cause simillar problems. For the $ it worth changing anyway.

Thanks : : NOI Couldn't hurt to pull the caliper off and pop out the cylinder. Assuming it pops out easily, we can probably rule out the caliper as the problem and you'll need to check the line. Of course, you'll have to do a caliper rebuild, but I suspect you'd want to do one anyway. No biggie there.
