I'm unsure if my brakes are too spongy after the 280mm front upgrade and rear disc upgrade (all 4-stud).
I can manage to press the pedal right to the floor at standstill, and I don't think I could do this with the old brakes. They do seem to have no issues slowing me down, but if I can push the pedal to the floor then I'm assuming I'm losing some stopping power as I'd be able to do this when braking harshly if ever needed.
They were bled fully with new fluid, but I'm unsure if there could still be air in the system? We used a one-man setup to change the fluid appeared to work fine.
