Replaced pads rotors calipers blead them out and
brake pedal still drops but will build up if pumped
Bad master cylinder. Replace master cylinder.
Pedal was hard prior to replacement so master cylinder would be the problem
Before blaming master cylinder recheck calipers making sure not binding up anywhere and pads are seated correctly in caliper. Also check caliper bolts making sure they are tight also.
Did all of that
Well if everything checked out ok it has to be the master cylinder but if you change out master cylinder and it does the same thing then the problem is somewhere in the work you just done.
Prior to the the brake job a month and a half ago the brake pedal got hard to push almost like it wasn't going to stop but thank you for all the advise I'll triple check everything
