I was doing the brakes on my miata, and turns out the rear passenger caliper is fucked. Dust boot ripped, piston won’t retract. The pads on that side we’re worn completely down, and the other side had decent life left. So, I can get Advance auto to get me ones tomorrow for $80 per, or Mazda on Tuesday for $120. Is refurbs through advance a bad idea, or worth saving$80?
