Brake pad backing / clips?
Hi folks,
In the midst of doing brakes all around on my '93 GTS (early '93). New rotors and pads for the rear, new pads for the front (rotors were thick enough to be turned).
Anyway, the new pads are just pads - nothing else in the box. The old pads, at least on the front, have a backing plate with clips that seat into the pistons. I have two questions here:
1. Are these backing plates / clips always used? I didn't see a mention of them on John Pirtle's page. Maybe they're used only on GTSs?
2. Can I reuse the backing plates?
Thanks,
Paul

Every piston has a damper pad - different sizes front and rear.
Four per caliper and $6 to $9 each.
Yes we stock them 8>)

Get the dampers.
My brakes always squealed like crazy at low speeds. I always had a mechanic change the pads rotors when needed.
On the car's last brake job, I did it myself. Found there were no dampers installed previously. I put the dampers on with the new brakes and now the car is squeal free.
I love the dampers.

Well, the backing plates came off the old pads pretty easily, and are in decent shape. Now the question is, what to use to adhere them to the new pads?
I was thinking either high-temp silicone adhesive or Pliobond. Pliobond is rated to 500F, which I think should be enough for the back of the pads....
BTW, I bought the Centric OE formulation semi-metallics from Rockauto (actually made by Ferodo), just in case anyone else is shopping and is wondering what they will (or won't) get with the pads. When I bought the Monroe OE types for my wife's Cayenne, they came with everything (clips, sensors, etc).

I've never received these in the box with pads. Always sold separately.
I've glued the little pieces to the back of the pads a few times with hi-temp silicone, and they work OK for a while. I ended up regluing the last set a few tiimes over the life of the pads, easy during annual caliper removal/ inspection when fluid is swapped. If you have a higher-temp adhesive option it might be worth a try.

No. But I did take the little needle files to the sensor slot to clear the paint and flashing before skipping the sensors in. Results show up at the next pad change when the sensrs can be removed without damage.
