Got the discs, and new pads.

I must say those old discs needed the small sledge hammer to get them off!
But the new ones went on with no force at all.

Anyhow the only hickup I had was that one of the pistons (rear bottom of passenger caliper - girling) was absolutely stuck. I took the hammer at it and could not get it to budge. The seals around most of the pistons looked fine, that one had a slight tear so I guess it corroded from the inside. All other pistons pushed in easily. As a result, I could not fit the new pad at the back side of that caliper, so I reused an older pad that was around 70% good, smooth wear. I guess no major harm for a while, except the slight weaker braking at the right side due to the 'useless' piston.

Questions: If I have a piston that is well loose, but the seal looks partly torn, can I just replace the seal from the outside, and save the hastle of removing the caliper , i.e. work while the caliper is unmounted but still connected to the brake lines?

Reason why I am asking is that my rear calipers have torn seals (all of them, but still can be pushed in and still produce relatively even wear. I already have the new rebuild seals, so to save the work can I just get them sticking out somewhat (like a fully worn pad, clean and lube the piston with brake fluid, then work them till they are smooth and push them in, and finally replace the seals ?

I am assuming the above would be OK for a half-assed job that would prevent further deterioration of the calipers...for now. Let me know.
