While pushing the piston back into the caliper to swap out brake pads, I accidentally ripped the rubber boot around the piston. I believe the rebuild kits are only like $15 at Autozone, does anyone have any advice or anything about replacing these things?

How does the old boot come out?

 

Mine ripped too.. I'm just buying a Caliper Repair Kit from Honda.. My cost is $15..

 

haynes manuals do a good job of explaining how to repair the boot
autozone sells ther manuals for like 14.99 or something
