Checking Frt Caliper Pistons...


Recommended Posts

I'm in the middle of a brake job today, and everything is going to plan, except as I'm cleaning everything up and making sure everything is all good, I can't move the big caliper piston.

How do I "check the front Cailper Piston" in order to be sure it isn't frozen? C- clamp? How? :unsure:

Here's what I just took off...pathetic, huh? Click pic.

With your user name being what it is I'd have to be hard pressed. I, however, do find it entertaining.

The definition of an enthusiast is "a person filled with enthusiasm" or " one who is ardently attached to a cause, object, or pursuit." Then there is my personal favorite "one who tends to become ardently absorbed in an interest." I would call the last one fanatic, bordering on unhealthy. I think I'd rather be an enthusiast as opposed to a fanatic.

CADS RULE DUDES! Alright Alright Alright...

Typically the piston will push in using a c-clamp, if yours is not pushing in with a c-clamp, its cocked and frozen. As it is, look at your pads, it also looks like your slider was frozen due to the uneven pad wear. Clean and lube your sliders. If your calipers free up, make sure you replace the rubber slider bushings in the calipers given that you have all new parts.. Don't overlook the rear either and bleed all around.

One other thing, you might find that on this enthusiast's board, you might get more help with a better name, it turns me off, and I am sure it turns others off. Its easy to change. Lets us know how the new pads work out, I am curious how you like the drilled/slotted rotors

One more thing, the fronts push in with a c clamp, the rears screw in using a cube, I think you were talking about the front above

Thank you for your info.

The pistons do push in with the C clamp. They're good. I did just order new sliders and bushings though. Should probably just do new calipers all the way around. Rears are done. Simple.

And about the name... well, when I started in here back in 2004, before the board changed over to the current version, my Cad was a very large moneypit and acting like a real piece of c-rap back then. It is a '93. It fits her. Pretty sure most guys can handle the user name and get the joke. No worries.

funny how someone with a POS will nurse it along for 4 yrs? i think they really like it myself. yes i expect old worn out brake parts to look nasty. they get beat on. your new parts look nice. i would expect new stuff to look good. how does it perform on the street? or do they shine on the track?

Putting the newer CTS rims on a 93 STS was a good choice.

The result, to my eyes, is that your STS now looks like a 1997 Seville.

The 93 OEM rims are now very dated by comparison.

Nice looking car.

If that was my STS, I'd probably change my web name to "Timeless 93STS".

Did you replace the rear rotors also? Drilled?

About the name.......

I concur with BBF. In fact if it hadn't been for the fact that that BBF had posted to your thread, I would have passed on even reading it.

My first inclination was to advise you to sell your money pit & buy a Yugo. :P

If I recall correctly, the name caused some comments a few years back.

It may be a joke to you & some others, but then it is a turn-off to the rest of us.

Most of us are here because we like and respect these cars.

If you change the name, you may find that the responses that you will get will be more numerous, friendlier and more helpful.

Take Care,

Britt

Its funny you guys say this, I was NOT going to respond because of the name, but I responded to the issue and said my piece. I am glad to see, that it wasn't just me that was sensitive to the name and that you guys were also reluctant to respond. THAT is why I suggested changing the name...

It may be a joke, but 4 years later it doesn't come across as a joke. The car is 15 years old, it will need renovation and repair even the space shuttle needs work. Consider changing your name, you WILL get more help when you come here. The title at the top says, "For and by Cadillac Enthusiasts".

By the way here are my overheated pads, they are not that old

And here is the overheated rotor
