Pulling stubborn brake pads?
Hi folks,
Does anyone have a trick for pulling out the rear brake pads? Both inside pads, on each caliper, are stuck in pretty tight. This was a Cape Cod car, so I'm thinking the typical corrosion from the alloy calipers has taken place and gotten them pretty snug. I can't figure out a good way to gain some leverage to pull them out.
I've got the 4-pot rear calipers. The outside two pads, luckily, came out without too much work.
Thanks!

so, that puts a gaposis between pad material and disk.
[and hopefully he hasn't refilled his brake fluid since the last time the pads were installed -- or his car just wet the floor behind the FL wheel.]
Now, how does he separate rusted-on pad backing plate from caliper pot tops?
(A: Start wailing away with chisel+hammer on the pad plate backs?)

granted mine aren't usually that bad here in CA. However if they are stubborn, I usually spray them pretty good with cleaner and employ a flat-blade screwdriver in a manner similar to Ilko to push them apart

Push from the rear with the screwdriver? I'm having a tough time envisioning. Then I would need to pull the rear dust guard too in order to get at the back of the pad?
I used a thin flat-blade screwdriver to separate the spider/disks from the pad backing and pressed the pistons all the way in. That was amazingly simple.
Crap, I didn't think about the fluid res overflowing...

Stick the tip of the screwdriver in the bottom of the brake caliper, so it touches the bottom of the pad. the side of the blade will rest against the rotor hat. Hold the screwdriver by the handle and push it down. The brake pad will come off. Is that better?

Ah, so I'm digging the screwdriver into pad material?
I think I'm just going to grind a bit off the new ones rather than risk screwing up the calipers to remove the corrosion under the metal shims that hold the pad stiff on the top & bottom.

You're not digging into anything and you're not touching the caliper at all. You're pushing the pad out from the bottom. I've never damaged pads using that method, but hey - your call

Does this help? Sorry my wife's the better Photoshopper in the family...
You don't go inside the pad. There's no reason to go inside. You place the tip of the screwdriver at the bottom of the pad and push it out.

You can't pull them out if the vibration damper pads are still attached.
The pistons must be pressed fully into the calipers so the pads and vibration damper pads have enough space to come out. Or use a putty knife and seperate the pads from the dampers.
That's why for corroded or stuck pads, I release the caliper from the trailing arm for ease of accessibility.
