1994 4Runner Brake Problem

[SheckyZ28]

I have a '94 V6 4runner and am having problems with the front brakes. The lower retaining pin for the pads on the caliper is seized, and I can not get it out. The is hardly any room to get a good blow to it in hopes of breaking it loose. Any suggestions?

Nobody has had any problem doing a brake job on a 4runner???

Yes....just been there, actually.

Penetrating lube for a few hours still didn't help. Cut it off with a die grinder....then I had 2 ends siezed. Tried drilling, with a press, couldn't get it straight, ate part of the calliper.
At AutoValue, here in Canada, I replaced the calliper and all hardware for $50. No brainer....if it's seized really badly, I wouldn't worry too much: replace.


Hope this helps...

Thanks for the response. I actually picked up new caliper/anti-rattle pins this morning and figured I would try cutting the pin then knocking them out. Hopefully I will have better luck and not need to replace the caliper.

Was able to get it done last night by cutting the pin in half. The back half came out with a little hesitation. Then i ran the upper pin which i was able to get out through the back hole and knock out the front half. I took a while and a good beating to get it out finally, but was able to do it while everything was still on the 4runner. After that I think i wrapped the brake job up in about a minute. Its crazy to think how easy a brake job in this thing should be when compared to other cars, and then how much trouble it ended up being.

Guessing you just did the pads then? I found the process of hub removal and rebuild (seals, bearings etc) while doing disk rotor replacement to be a fair amount of effort.
