Darnit! Put a tear in rear caliper dust boot. Easy to fix?

So I'm NOT talking about the boots on the slide pin, but the one on the main piston.

Does anyone know if I can remove the old dust cover and install a new one without disassembling the whole thing?

Or should I just cry uncle, order up a pair of refurbishment kits, and overhaul the whole thing in the off season?

Easy fix. Just can be a pita to get the old boot out but you do not need to pop the piston out.

got any tips for getting the old one out without ripping it further?

There is a good description for a rear caliper rebuild on Seloc

How to Rebuild a Brembo Caliper - TechWiki

But I can't see how you would get the old boot off without removing the piston.

Yes, coming across that is what led to the question. Maybe I'm dense but it doesn't seem there is much detail at the end for getting the piston's dust boot back on, but I assume you'd normally do it after you had replaced the piston. The last caliper I rebuilt (on a civic, for the same basic reason) I did attempt to get the dust cover off and only succeeded in ripping it up, so I'll be buying the kit anyway as CYA, but someone has to have done this... I can't be the first! (or maybe i'm the only one anal enough?)

From looking at the pictures I think the boot is seated in a grove in the caliper as well as a groove in the piston (just like the boot on the slider pins) and it looks like it can only be removed after the piston is removed.
Installation would be in reverse order.

If you change rear pads frequently and if the seal is torn while using needle nose pliers to retract the piston (and this must happen sometimes),

I'd grind an old socket down to make a non-ripping tool for this.

IIRC, there are tools one can buy for that.

I'm afraid its worse than that. I have such a tool, but it went missing so I decided to go ahead with the job without it.

I have since re-discovered it and will not be lazy about using it on the rears from here forward.
