last year i swaped out the cutlass spindels and put the caprices ones in the with the caprice a arms and calipers, etc. I noticed since then that my brake pedel goes to the floor. i put new calipers on the front and pads, replaced all rear brake parts and put on a caprice master cylinder and it still feels like it goes down to far. is this normal? if not, what could possible be wrong?
