A Body Disc Brake Swap 101

Hitting the casting with a shop hammer will cause the tierod end to dislodge but could also cause a hairline crack in the casting. If you have a pickle fork, use it.
The steel backing plates on brake pads are stamped out with wide open tolerences so one size fits all rough castings. I'll tap a wedge between the outer pad and the rotors center hub to force that pad upward then tap the 2 top ears down against the casting. When the pads are properly fitted to the caliper that messy blue glue is not required and the subsequent click noise does not occur.
