I was able to get a caliber rebuilt kit (contain one dust boot and a piston seal (ring)) at my local chain auto store for $5.

I was able to pry of the old one with a screw driver and with a little working able to install the new boot without even disconnecting the break fluid line. Putting lub on the boot healp. I used Permatex Ceramic Extreme Break Parts Lub. Hope it will not deteriorate rubber. It does say it is 100% syntetic and it does say safe on rubber and plastic. I am not that worry on the boot can replace the boot for $5. But I did use this stuff on the break slider rubber bushing. Like I said I hope this stuff is safe on rubber and plastic as advertised.

Also replace beak pad sensor. $10 at local chain auto store. Old one interpenetrated

Will test drive tomorrow.
