Default Frozen Caliper Bolt

I set out Sunday to do a brake job (WS6 Store cross drilled rotors & Hawk pads) on my 2000 T/A WS6. The first wheel went easily enough. On the second (rear) wheel the 15mm bolt that holds the caliper frame to the axle flange is rusted solid. I busted a socket with breaker bar, and of course now the head is rounded. I had soaked it with PB Blaster for a couple hours tried vice grips, heat. I let it soak overnight and was going to try a pipe wrench on it tonight. Anyboday have any other ideas/run into this?

Working on cars would be so much fun if not for rusted bolts.....

Thanks


Paul

If it is rounded out you might need to use the cutter sockets. I got a set for $20 at the zone. The reverse cut ones that grab as you go in reverse are what you want. Spin the steering wheel so you can get a good angle on it and whack it a couple times straight on the head and see if that doesn't help before you try and cut it off. No need to get crazy but a sound couple smacks may help.

Good luck - those never froze on me but some hub to spindle bolts did. I feel your pain.

I've used these on rounded nuts/bolts: http://www.sears.com/sr/javasr/produ...TOOL&ihtoken=1
You use them with an impact wrench, and they literally cut into the bad nut or bolt. These are about the best extractors that I've ever used.

When I installed my WS6 Store rotors, I had one frozen bolt and one frozen bleeder (both on the right front)


After a little heat, they came out easily

Thanks all, pipe wrench finally broke it free, thankfully without breaking the bolt.

Don't forget a little "never-seeze" on the threads when you re-assemble!

hello guys, i have a quick question for the same situation. I noticed you mentioned heating the bolt. I dont have a torch in the garage, would one of the mini propane torches do the job that i can purchase from sears?

Actually, you don't want to heat the bolt. You want to heat the bracket, so it expands, and releases the bolt. The mini torch might work.

OTOH he may want to heat the bolt, perhaps it will bust the bracket from the expanding bolt and he will then be able to pull the bolt out!!!
