A bit like this gentleman's quandary: https://www.yotatech.com/forums/f120...roblem-126535/
My brakes were working fairly okay, they would occasionally slip, meaning the pedal height would drop while I was braking, causing the brakes to disengage and me having to basically push the pedal to the floor to reengage. Now, every time I go to brake, same thing, I feel that the drums are the only parts working and the discs aren't engaging. I just put new calipers, pads, rotors, in front and drums shoes and all the hardware in the back in december. Its like my discs aren't engaging and the pedal just engages the back brakes! Sorry for rambling but I have tried everything, bled the brakes, cleaned master cylinder and lines, checked everything for leaks, nothing. Anyway TIA for help!

 

Dropped anew master cylinder and bled everything and they work great
