Floating pin seized in carrier. How to un seize it

[Pesty]

I think they are called float pins.

Anyway one of them it seized rock solid. Will not budge at all. It's currently sat in a vice where I've been trying to move it back and forth with no joy at all

I've soaked it in plus gas and given up for the day. A it's raining and b I'm pissed off. Another easy job turned into a fk up


Thanks in advance

Patience, heat and/or brute force.

The latter obviously risks the pin breaking.

If the first approach doesnt work, then you'll need a good heat source to try and help release it.

Hi Steve thanks.

I was going to get the blow torch on it but I can't get the rubber cover released from the carrier side.

I'll try again tomorrow

I feel your pain brother, honestly. I had exactly the same issue on a rear caliper where the pin was rusted into the carrier along with the banjo of the handbrake cable as well. Couldn't add heat as it would have melted the shroud adjacent to it, and also possibly could have mullered the Cable which cost the equivalent of a second mortgage from Mitsubishi.

I ended up doing a bit of a bodge, I bent the lower carrier arm up, placed a socket over the top of the pin which was larger than the pin itself but allowed me to tap the top of the carrier down and gently managed to get a gap, after which I gave it 2 days of plus gas and managed to get enough purchase with grips to free it off.
The pin was knackered but the carrier was fine after I bent it back into shape, which was the main aim.

I bloody hate those jobs which should take half an hour but end up taking skin off the knuckles and 3 more days.

Crap isnt it.

Well I tried for two days straight leaving it over night soaking in plus gas ( has that stuff ever worked for anybody?)

Had a large breaker bar and the only thing that was going to break was the vice off the top off the bench.

Ordered a second hand caliper from ebay I asked if the float pine were included and free

He said yes they were. He meant they were free , not free

Soooo anyway today I got those pins out cleaned them up and got them greased up nice and put them on the car. Took over a week and cost an extra 35 quid

Careful with heating it, as some caliper designs have o-rings inside there to reduce brake squeal, etc, if you melt 'em it'll be even worse to get out, check the other side first and see if there's any in there.
