Rear Calipers

[johnrem46]

Trying to replace my rear calipers. The problem is that the calipers on the car are rusted solid and I can not get the bolts out. I do not want to strip the heads . Is there anything that I can use to loosen the rust that works well and fast?:confused

A six point socket and a breaker bar should do it, sometimes soaking with penetrating oil and trying to tighten first helps too. PG.

PB blaster works good but best not rush it soak it several times another good penetrating oil is Kroil but its harder to find.

Like Bossvette, I've had success with PB Blaster.

Me personally.... I'd spray them with PB in the morning, then again in the afternoon, and once before bed. Then, I'd start the next morning. That should do the trick.

I had the same problem. Lots of PB blaster, Breaker bar, a few 5/8 sockets (broke all 3 of mine) cheater pipe (gives more leverage than just the breaker bar)
If you strip it, then get yourself a set of bolt extractors. they are a life saver for these old cars.

Penetrating oil and a large wrench are your best bet.
A torch of some kind could help. Heat up the are around the bolt can help.
An impact wrench would be another thing you could try.

Bolt extractors are a useful, but from personal experience they are not a life saver. I was using an impact wrench to loosen a bolt and it broke the head clean off. I almost broke the extractor I was using. Finally, I just drilled out the bolt and re-tapped the hole.

Good Luck!

Basically the same story here. Damn thing just didn't want to come out. Eventually snapped the bolt head. Had to do the whole extractor / retapping song & dance. Well, not me, but my mechanic. I just watched. Of course, that means that I pay for that peep show. :L

Thanks everyone.. Soaked the bolts really good for a few days.. Got a good 6 point scoket and a breaker bar. had to use a hammer on the last one but they all came out without breaking anything.. Again thank you !!
