I was servicing the front brakes on my '93 940 Turbo Wagon, and one of the lower Guide Pins is badly rusted, and stuck in the Caliper Carrier. I've been hitting it with penetrating fluid, heating with a torch, and striking with a hammer -- all to no availe.

The next logical move seems to be replace the caliper carrier all together.

Does anyone else have any thoughts/advice on the subject?

Thanks,

Jeff Pierce

Put some rubber safe grease on the inside and outside of the boots of the guide pins at least once a year. Saves $ and time.

Even though I read you already ordered a new one, here's my $0.02 (hey, 1750 of those and your part's payed for...)

I was quoted close to $100 (including tax) for that carrier by a main dealer here in the Netherlands. Sod that me thinks, lets put some more work into that.
Clamped on big but expendable mole grips (AKA vice clamps), heated the carrier for about 5 minutes with 2 high powered propane torches while pushing and pulling (turning motion) on the pin and trying to work it out, occasionally hitting the pin/clamp assembly outward with a 3 pound sledge. Eventually it came out. Cleaned the bore (old drill bit, slightly undersized, slowest possible speed) and popped in a new pin with plenty of copper grease. If the part's otherwise scrap anyway, the use of increasingly heavy handed techniques to save it becomes feasible.

Works perfectly now.

To finish that brake job (and I'm going for the "pissing off the by-the-book crowd" award now) I got out the angle grinder and remved the wear lip from the outer edge of the brake disks, and took a tenth or so off the small end of the brake pad lining to make it clear the wear lip on the hubside of the brake disks and sit straight right away.

Jeff-

I've been driving my 940 (w/ABS) with it's frozen caliper pin for two months, until I saw your post. I called voluparts, after reading Chris' and Paul's response, and ordered the caliper bracket and a pin for $45. The pin was ten and the bracket was thirty-five. I think it's the only way to go. You can't play games with brakes. I thought the price was a little steep, but I need it and they had it.

After calling several places, none of whom wanted to sell me the carrier bracket without a new caliper to the tune of $300, I was beginning to think this was something no longer available... (Junkyards wouldn't even sell it to me! Rebuilt calipers don't include it!)

www.voluparts.com to the rescue! They have them for $20 each I think, I ordered pins ($10 each)at the same time and they were nice enough to lube them up and pop them in!

Paul,

Great parts resource. They had a new one in stock ($35).


Thanks,

One effective way to free the pin is to turn it back and forth while trying to extract it. It's not the easiest thing to do, and if it doesn't work, you are going to be in the market for a caliper carrier. There is really no way around that except to prevent it, unfortunately. The good thing is, the caliper carriers aren't hideously expensive, just inconvenient because you have to GET the part before you can put it in :)

At some point, even if you DO get the pin out, it becomes silly to put it back in, since it's pitted and rusty. To rid it of the pits and the rust, you have to slice a layer off, and then the tolerances get bigger... plus you can't easily polish the inside of the caliper guide pin bore anyway. You see what I'm saying I'm sure... you're probably just better off replacing the part.
