Sticky front piston

    I'm replacing the front pads in my '03 Sequoia. The first side was a breeze! How cool to use the "race style pad". However, I was struggling to do the passenger side pad on the inboard side of the rotor as the piston wouldn't fully retract no matter what I did with it. I was going to remove the entire caliper and give it the old C clamp squeeze, but the bolt holding the flexible portion of the brake line is broken off at the head. I'll have to drill and tap that hole again just to free up the caliper without mangling the hard line. Once I get the caliper free by either drilling and tapping the bolt or removing and plugging the hard line while I mess with the caliper, then I get to mess with the reluctant piston. Any tips or tricks you guys like there? Should I just replace it? I got the piston squeezed back enough to get the top of the new pad in, but the lower piston won't retract enough to get the bottom of the pad slid in. Right now I'm using an older thinner pad in the interim.

    Thoughts?

    Thanks,

    I'd just replace it.

    Good call. I'd have already done that, but the bold holding the hard line to the suspension was previously snapped off and needs to be drilled and re-tapped or I'll end up replacing the hard line too. In the meantime I snuck an old but usable pad that would fit on that side. Not recommended, but not for long either. Just a band aide until I can drill the offending bolt out.
