gm brake calipers?

I have a disc brake kit and they use gm calipers. I have never had a gm product before. I have never put on brakes to anything but ford pickups or dodge cars. Im wondering how to put the pads into the caliper. I was able to get one side on, the side without the peice that you have to push in to release the caliper from the braket. I have two clips but don't know were they go or how they go. Any help would be great. I put one side on and just held the one side in place, I know its not right but just want to see how it worked. The pads are up against the rotors it seems i have a space issue which i think might be from the pad. Once again any help i would love to know. thanks.

The pads lay in the caliper. The clips go on the inside pad and it clips into the piston. You may have to push the piston further into the caliper to get it to fit on the rotor. New thick rotors and new thick pads mean you'll have to pretty much bottom out the piston to get enough clearance to slip it on the rotor.

They're pretty straight forward. One pad on the inside with a clip, the other one just rests on the outside. Two of the pads should have little steel tabs on them. They are the wear indicators and they typically go on the inside of the rotor.

I'm not familiar with a caliper where you have to push something to release the caliper from the bracket. I'm familiar with the kind Curtis is talking about, but it sounds like yours is not that kind. Do you know what GM's original application for your calipers is?

If at all possible, could you post a picture so we can better help you out? If not, I'm sure we can "talk" you through this, it'll just take a bit of time.

I'll take a shot or two of the caliper/pad assembly on my Monte. Might be of some help-- at least I hope so.


In a while, Chet.

These caliper shots probably aren't going to be of much "exact" help (since the age/type of my car are different than your application), but most GM's are pretty similiar in the basic form. Be forwarned, however, that you may need a tetanus booster following this....

Ok tried it and i seemed to get it to work but know i have four clips that came in the box and i put one on each shoe but still have two left over. in the picture i show the clip going in a hole and then to the outside but i have it across the whole shoe. Should it be both clips in the hole on the shoe and then into the cliaper? Oh and i found out why the brake was tight on the rotors.

That sounds right.

Some of those GM brake pads like the D52 / 728A 's fit a wide variety of applications (cars and pickups), so it is possible that they might include more than one style of clip.

Those are some pretty nasty looking calipers... I'd consider using them as cores and getting a pair of rebuilt ones. They're only $15 - $20 each.

Yup. But considering that the car hasn't moved at all in 8 years, and hasn't moved under it's own power in 13 years, I'd say they look pretty good....

No, really, before I get done, every single brake part on that car will be new. Brakes are too vital of a component to cheap out on.

That picture shows the spring clip oriented backwards. The fingers at the ends of the spring clip hold it to the back of the pad. The top of the pad then fits into the caliper and the extended (bent) finger on the bottom of the spring clip fits into the opening in the caliper piston. Note also that the other pad has two small tabs at the top that are bent 90 degrees to the back of the pad. Once you get this pad into the caliper, you're supposed to squeeze these two tabs down to keep this pad from rattling in the caliper.
