When I went to replace my my brake pad on my 1988 Toyota 4runner I couldn't get the pins out. I soaked them in pb blaster and the likes but nothing. they seem to be rusted in place. Anyone have any ideas on getting them out. Thanks a million

You might have to take the calipers off so you can really hit them good with a hammer and punch.

had to do the same thing with mine, with the addition of a torch.

i had to PB and tap mine with a hammer. don't forget to brake clean the PB off the rotors

Once you get them out be sure to polish them with steel wool so the new brake pads slide. I put the pins in the drill and hold them on WD40 soaked steel wool. It makes them nice and shiny.

sorry to interrupt, but how the hell do i post my own thread?

I tried all that, I actual have an extra pair of calipers Which I think i will drill them out with a drill press. I soaked them for 36 hours and then hit them and just crushed the pins into a wedge shape but they didn't move. WISH me luck drilling a straight hole. Any other ideas before I drill.

have you compressed the piston yet? that might free the binding. the paper clips are out of the pins too right ? just checking

the set I talking about are off the truck

If you've not figured it out already, go to the main page and hit "new thread" directly under "home".

Sean.......since you've crunched the pins up, grind them down to the original diameter, if you have any way to do that. Otherwise, you may need to cut the crunched ends off flush to the caliper and continue to try and drive them out. But, if they're so welded in there that penetrant and/or heat isn't working, you may need to cut flush on every side and drill, like you said. Start with a smaller bit and go slow.

So you know, the way to work something like is to firmly tap, tap, tap, tap, tap. Not beat on them. Sometimes you have to tap on the part and not the hardware, too. In this case, the calipers. All around the pins. It's tedious, I know. But, beating on the hardware is what gets you where you are.

thanks for the info ill try grinding then drilling if i have to

I had to remove my calipers and knock out the pins with a hammer and punch. If you do that you need to bleed the brakes since you disconnect the brake lines taking off the caliper.

My pins were pretty beat up once I got them out so I bought new ones at the dealer. They were only $1-2 each if I remember correctly.

If you take a dremel with a small cutting disk, you can cut each pin at a couple of spots (right near where the pin goes through the holes in the pads). You are essentially cutting off a piece (1"-1.5" long) from the center of each pin. Then, you punch them out from the middle of the caliper outward, if that makes sense. It is much easier to punch the remaining pieces of pin out (you're only pushing the piece of pin out through one hole in the caliper instead of two... it makes a big difference, and no drilling required.) I did this with the calipers still mounted on the 4Runner.

Anyways, that's how I did the ones on my '93 4Runner. The previous owner had mushroomed the end of each caliper pin.

Thanks guys! I ended up taking the angle grinder to them and manged to punch out what was left. Soaked them to get them clean and then took a wire wheel to them. I going to paint them tomorrow with the random cans of leftover paint I have should be some interesting colors.

Put antisieze on them when you reassemble and avoid this mess next time!

I don`t know what to say but I replace the pins with new when I change pads they are not that expensive .

I also never seize them because it will no doubt be me taking them apart. I have some to do in the next couple of days.
