Driving home from work tonight and my brake pedal started to go lower and lower to the floor before the brakes would engage then it went fine for 5 mins then slowly got lower to the floor again like there is no pressure, i checked for any signs of leaks couldn't find any and checked my brake fluid level still at the full mark if any one got any suggestions would reallly appreciate it as this is my daily driver!
Ive done the front callipers no air present in the lines pedal still lowers with hardly any pressure behind it
yeah i did the outer bleed nipple then the inner on both im thinking is it the brake servo or master cylinder
