OK so all my brake cylinder pistons have seized. I believe that when the brakes were “done” about 25 years ago (it’s not been driven since) the cylinders were also replaced so should be in good nick – if I can get the pistons out.
I’ve created an attachment so I can fit a foot pump to it, and have pumped it up to about 110 PSI but can’t get any more pressure into it. It’s been soaking in diesel for about a week already.
I’m thinking heat next…any top tips? e.g. how hot can I realistically heat it without causing damage?
