Stuck caliper slide pin

[Willie Williams]

So I am a DIY kind of “technician”. I have a 97 Honda Accord that haven’t had any brake service done since I owned the car, let alone before I bought it. I replaced the left rear brake pads but I can’t get the right rear done. I have a stuck caliper slide pin and I have no idea how to get it loose. Any suggestions will be greatly appreciated. Thank you very much

Please note: I don’t have any expensive tools (i.e. Snap-On, Matco, etc.) and I’m sort of a penny-pincher.

Honda’s and Nissan’s alike are known for the caliper guide pin going dry and rusting into place.
Remove the bolts that hold the caliper bracket to the spindle, suspend it with a wire coat hanger or short bungy cord to the top coil of the struts. Remove the pads and place in a safe spot.
Go by new pins with rubber boots. Cut the boot off the rusted in pin, exposing it. Combine equal parts automatic transmission fluid and the paint thinner acetone, this makes a good penetrating fluid. Squirt that liberally on the area that the protective boot used to sit on. It’s even easier if you can detatch the brake hose and Doo all this away from the car. Let your penetrating fluid soak in overnight or at least a few hours, then see if it can be turned out. If the hex head has started to strip, the just go get another caliper and bracket, then bleed the system.
If you can get the pin out, take a round wire brush and scrub the inside if that hole out very well. Dry fit the new pin in and make sure it moves freely. If not, brush it out a little more. I use a wooden dowel a bit smaller than the new pin, cut a careful, straight slice down about 2 inches in, then use some 180 grit sandpaper paper and cut a 2 inch strip off, wind it around the dowel after sliding it down the middle of it, then if possible, use a drill to spin that in the hole to really clean it out.

If the above suggestion doesn’t work (hopefully it does)
Assuming you have the caliper removed from the bracket.
Use a torch to heat the area around the pin and either using a socket and ratchet or vise grips to work the pin free..
You’ll need to get it fairly hot.

Get replacement bushings. Torch the seized pin with a propane or butane torch and rock it back and forth till you can get it loose. Dont use way too much pressure to get it out, like a socket and huge bar, you can actually break the pin. Clean the old pin and inside the caliper bracket with a file or something, regrease and reuse.
