Has anyone successfully reused the anti-squeal "spiders" when replacing their brake pads? If so, what did you use to adhere the spiders to the brake pad backing plate?

Did it on a 964 years ago. I just stuffed the "legs" in the pistons and slid the pads in. Did not use adhesive. Not sure if that's the correct approach but the brakes didn't squeak...

I did the same. I just fitted them into the depression where they are trapped between the pistons and the pads. No adhesive. No squeal.

Yep, same for me. As long as you don't abuse them taking the pads out they should be fine.

No spiders (in front) and no squeal. oem pads and rotors

i use to have spiders in the pads then i removed them after repainting the calipers no squeel anymore. the spiders do more harm than help honestly and the springs and retainers keep the pads in without issues.

I would put some EMP compound on them as replacement adhesive. Otherwise I see no reason why they can't be reused.

cgfen

yes
reuse
i do and use a silicone based adhesive to adhere to brake pad

pp000830,

What is this EMP compound, and where might I find it? I did a google search for it, but no joy.

P-daddy

Ditched them. No squealing.

Agree wholeheartedly with ditching the spiders! All they do is complicate/slow down the pad changing. A small smear of Lubro-moly hi-temp goop (can't remember the number on the tube but its got copper I think) on the back of the pad (and use the Porsche Textar pads) and no squeal. Zero noise after I don't know how many tens of k miles now

A noise suppressing compound used on automotive calipers to provide a rubbery like attachment of pad backing plates to the caliper frame or piston. Has the consistency of calk is heat resistant and can be purchased at an auto parts store. A common auto supply. Use it sparingly as to not to get any on the piston seals or the pad backing plate beyond the spiders mounting rubber disc potentially glueing the seals to the pad backing plates.

Okay, I just finished installing new front brake pads. Not the ordeal I was expecting at all. Here are a few things I learned:

1. To take the pads out without dismounting the calipers, the spiders need to be detached. I chose to loosen the entire shim plate with spiders using a stiff, wide scraper. To do this, the pistons must be retracted first--otherwise you don't have room to get scraper between between the pad backing plate and the shim. Just get the corner of the scraper started, then wiggle and push until the ENTIRE shim plate is detached from the backing plate. Then the old brake pad can be removed.

2. If you are going to reuse the sensors, carefully lever them out with the tip of a screwdriver. If you pull on the wires to remove them, you will likely be buying new sensors.

3. If you are going to reuse the spiders, carefully remove them from the shim plate with the scraper, and put them back in the pistons. Make sure they are fully seated.

4. Attach the sensor to the new pad.

5. Treat the back of the new pad, which usually come with the shim plate attached, with your favorite secret sauce to reduce noise. I fell back on my long-time favorite, LM High-Tack Lube Spray. I've never had brakes squeal after using this stuff, but sadly, the can is almost empty, and no more to be found. Wurth HHS-2000 may be the closest thing.

6. I chose not to use the anti-squeal stuff that is prevalent at the local parts stores. I tried it once, and while the brakes didn't squeal, it dried into a rubbery goop that pulled out the piston dust seals next time I changed pads.

Happy Independence Day to all of you fortunate enough to live in the USA!
