I have melted my stock dust boots but im fairly confident the pistons arent chipped or cracked, and I have solid braking performance, so maybe the full rebuild including new seals is overkill at the moment?

I was concerned something might damage the seal if the dust boots are left in current condition... Is this valid?

With only one more track weekend before the new year I'd prefer to defer the 600+ expense until after Christmas...

Any help or input would be greatly appreciated.

Thanks
I dont think changing the seals without a full piston removal will be possible unfortunately. The only thing you can do is clean the tops of the pistons while they are protuding, and re-grease the tops. The dust boot swap is all you can do without removing the pistons ...
