So I went to do a quick brake job on my 04 this morning. Get the new pads on and the caliper wont fit. the caliper will not go over the caliper bracket bolt pads with the new brake pads installed. Are these free floating pins? Or are they threaded? Whatever they are, they are seized up bad. I'm wondering if I should just buy new caliper brackets.

they are free floating pins. Mine were sezed up as well had to go out and buy a new caliper bracket, bracket slides, and the little rubber boot that goes around it. When putting the new one on put a good amount of silicone grease on it that way the chanses of sezing up again will go down.

I just used a c clamp to open mine back up, they will slowly compress when they arnt installed, I believe auto part stores have an actually tool to fix that as well

Sounds like the pins are frozen.. Use some heat to try and get them out and then get new pins. Might be cheaper then getting a whole new bracket.

Lol. I hope he did it. If too hard to do it, just open a bit the drain and push the caliper back (some fluid will come out), then close it, and insert your new pads. In case you let some air in, you will have to fill up and purge the brake fluid.

Reading this thread, I made a trip to the dealer to get prices for the caliper pins, boots, bolts, and bracket.

The parts-counter guy gave me part-numbers and prices, but advised me to just buy a remanufactured caliper.

I only went to the dealer because I have a full front end rebuild coming up in a week and I gotta have everything I need to get it all done the same day.

I ended up not buying anything... gonna take a chance that my shop guy will be able to get the rotor and pads replaced without a problem. Got 136K on her.

c-clamp the pistons back in, pushing brake fluid back into your reservoir. I helps to pop the top on the reservoir so you're not further pressurizing the lines

They actually make a caliper spreader for just this thing. Most parts stores sell them. C-clamp works also.

Pop your brake fluid cap off. Wrap a couple rags around the neck because if it's already full, you'll push fluid out.

The piston is that big center piece in the caliper. Push it back with the tool until it's flush. Insert pads, good to go.

Make sure that you put the cap back on the brake bottle and pump the brakes a few times to get pressure back.

You guys are killin me! I know how to push the pistons back. That's not the problem. Problem is that the guide pins and the caliper bracket have became one piece of solid rust. I bought new caliper brackets/ guide pins/ bolts today. Just need to track down some of the rubber guide pin boots.

Well too bad it wasn't simple. You never said you knew how to do the job, so it's easiest to start with the simple suggestions.

At least we gave you a chuckle.

No, I was just being funny and carrying on with the (now known) irrelevant tip of the piston thing.

Less funny I suppose since my sarcastic humor fell flat. XD

The rubber peices should come with the disc brake hardware kit. It comes with pad shims and new rubber boots and the rubber ring thing that goes on the end of one pin per side. If you have not grabbed one I reccomend it as I have had issues with the pad shims making a lot of noise after reusing them

Just an aftermarket caliper hardware kit, or do you have a Delco part-number?
