What about a impact wrench with an extention?If I was looking at the right parts diagram the bolt is at the top and inside surface of the caliper.Is this the bolt.I'm getting ready to do my 964 brakes for the frist time(if my rotors ever get here)and it would be nice to know.

 

Perhaps that might work, but in my case the bolt is already rounded out. If I had to do it all over again, I would probably:

- let it have a good soaking in my silicone spray
- use a brand new allen socket with a 19" extension, and 'pop it'.

that technique worked on the other bolts, but after I stripped this one out.

 

For most of the rusty bolts I struggled with this winter, I soaked them for a week in Liquid Wrench (spraying daily) and used the longest breaker bar I could find to sharply "crack" them.

p.s. I found that 2' lengths of steel exhaust pipe makes great breaker bars - add as many sections as you need for additional length.

 

If you look at post #4 i show the hole you need to go thru to reach the bolt on the rear. Not sure you would be able to get a impact wrench in there. I used a 3' breaker bar and gave a snapping motion and they broke loose. They are a real PITA !

 

He said he would use an extension for putting it through that hole.

I use the hollow jack handle of my Craftsman Alum jack as a 'convincer'. It comes appart in (2) 24" or so lengths for different jobs.

 

Thanks jimq.Now I understand what the little hard to get to hole is for.It l looks like someone's idea of a sick joke.

 

I did that too but got tired of taking my jack apart.

p.s. It is temptng to replace those caliper bolts with stainless, isn't it?

 

Stainless? Nah, I would be worried about it breaking or something. I admit that I don't remember much of my chem classes, but I know there are different strengths for different materials, and I would not want to risk it. In fact, I believe once you remove these bolts your supposed to only put brand new ones back in. I am guessing this is for fatigue reasons? I don't know exactly.

But yeah I sure to wish that thing had the corrosion properties of stainless for sure.

 

Sorry - I guess you missed the earlier thread.

I just tried a #13 Craftsman Bolt-Out (image below) and its grabbing and locking onto the (round) outside of the upper bolt on the rear caliper. Retail for the whole set is $20USD but I bought mine on sale for $10USD. Its worth having around for other problems.



There is a tool for everything.

 

Ah! Jason I will try that this weekend and report back. Thx for the pic!

 

And apparently a picture to go with it!

 

The bolt out tool is AMAZING. If you round off an exhaust bolt or something just slap that on there and it feels like it is going to break then, BAM it comes off!! Love it. Best 20.00 I’ve ever spent.

 

This is exactly what I was talking about in my previous post.
