PostSubject: Frozen brake caliper pistons   Tue May 24, 2011 5:00 pm

I tried pumping them out with the brake lever, got them out a certain distance, but I think I mightve blown a seal in the master cylinder, as I cant bleed it & get any pressure thru now, pumping the lever just puts thru drips rather than squirts.
i tried blowing them out with compressed air but didnt work.
have to wait for master cylinder kit to come before I can try pumping them out with brake system again.
are there any other ways to get frozen caliper pistons out???

well u fellahs are on top form today, no doubt. i thought about that 'blew a seal' thing, wondered if you lot would go down that road...shoulda worded it differently, but apparently even my boss laughed so...anyway, does anyone actually have any credible, known solutions for getting frozen calipers outta pistons, when I dont have the convenience of the hydraulic system to push 'em out...? the master cylinder kit will take a week or so to get here...

I've got a vacuum pump you can borrow Brett. Might not help till you get the rebuild kit but you can give it a go.

thanks, can u explain to me what it is & what it does? (excuse my ignorance) is it like a vacuum cleaner...? would have to be super powerful to get these out!
i googled & read that some people have used a grease gun & pumped the thing full of grease, apparently a grease gun has quite high psi. would have to see if the grease gun would fit onto/over the bleed nipple. & then block off the banjo hole. i think.
can you get varying attachments for grease guns?

Its basically a hand pump that you use to suck brake fluid through the pipes when youre bleeding them. Like I said, its unlikely to unstick the pistone but it'll make it easier to get it working afterwards. The grease gun sounds like a plan. You could always connectit up to a compressor on a low pressure and stand back. Have you attacked it with CRC already?

with the caliper together get a piece of wood that fits between the calipers but is skinny enough to let the pistons come out most of the travel, then blow compressed air into the banjo hole with a duster gun, you will have to get a good seal arount the shaft of the gun and the pistons should cum free

sorry couldnt help myself

thanku Slaytanica & Jon, i knew the voices of sanity would return eventually Very Happy
I think once the master cycl is rekitted that it should push the fluid thru anyway, I hope; otherwise I'll be comin for that pump
Tried the compressor, wasnt enough.
will have to investigate other possibilities, tryin to find out more about the grease gun method, apparently they have a lot more psi than the compressor

went to see the mechanic & asked him.
he said wait until the master cylinder kit arrives & then use the brake system to push them out.

lots of WD40. a piece of 4 x 2, and a liberal pounding with a hammer or rubber mallet has worked for me before. (and I aint talking about penertrating seals or blowing them. It took me a while to get that one, but then again, not too many seals up this way, unlike that sub -antarctic town of Wellywood. Is there something your not telling us Woody?)

anyone know where to buy different sizes of grease nipples (zerk fittings) ?
apparently the way to go is put a zerk fitting into the banjo bolt hole, then pump the caliper full of grease.

Sorry. I'd suggest Repco but the kids in there probably wouldn't have a clue what you were talking about. I tried to explain anti seize compound for half an hour to them. They said it didn't exist. A month later, there it was on the shelf.
