When I removed my wheels to investigate my lack of braking power, I could easily tell my caliper pistons were frozen in the retracted position. I definitely had rear brakes only. How could I tell? Because the rotors had a nice, unmolested covering of rust instead of wear where the pads press against the rotors. Your rotors may not be so obvious, but you won’t know until you check. Mine were also below minimum thickness; way below, like .389”!!!! <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Sometimes the calipers can be rebuilt easily by you. The seal kit (D1ABBM-73425) is about $50 from Nissan. If you cannot do them yourself, you can consider sending them to White Post Restorations in Virginia or Karp’s Brake Service in California. Be aware that both vendors are backlogged and/or slow to respond due to Covid-19.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>You might also tell us where you’re located.
