This is how I replaced the rotors and pads on the front brakes of my 2004 Nissan Quest minivan. Should be similar to most other Nissans that share the FF-L platform such as the Altima or Maxima. I don’t have a manual or such for the vehicle so for entertainment use only.
These where worn down plus they’d warped on a recent trip to the mountains.
Caliper bolts top and bottom – 17mm
Floating caliper off and tucked out of way. Rest it on something so no stress on brake lines.
They are really, really tough to get off. First I heated them with a propane torch (careful of the rubber bits) then I used a 22mm wrench and beat on it with a hammer until they broke free. Once loose switched to a 22mm socket and socket wrench.
Caliper off finally
Put the new rotor on (clean with brake fluid cleaner first!) then fixed bit of the caliper goes on.
Loosen brake res cap lid a bit. When pushing in the caliper pistons a little fluid make leak out – I put out so paper towel to catch it.
Push the two pistons back in to caliper – the trick is to get both at once. I used a piece of wood and a C-clamp.
Caliper goes back on. All finished. Looks nice and shiny for now.
