Ok Guys im tring to get my head around some brake calculations.

my brake set-up was this below
master cylinder 22.2mm
front calipers 2x 53.9
rear cylinders 2x 20.6

I have since changed the setup to
master cylinder 20.6mm
front calipers 2x 53.9
rear cylinders 2x 20.6

since the change i have noticed that the pedal has quite a bit more travel. the problem is if i push with all my strength i can almost get the brake pedal to hit the bulk head.

there is no air in the system and the wheels will lock at about half way towards the bulk head. im just worried that i can push the pedal well beyond the point where the wheels lock up.

my iva is approaching soon and i wouldn't want to fail because of this.

should i just get a longer push rod or should i be looking for a different solution?
