I have got a floor mounted pedal box, balance bar with 2 Girling brake cylinders fitted with a remote reservoir. The problem is that after bleeding all of the brakes, when a depress the brake pedal I am not confident that there is enough force on the front discs and back drum to stop after travelling at many MPH.

I can't see any evidence of leaks, so assume all connections are OK.

Any suggestions would be greatly appreciated

Thanks

have you tried em yet ?

they will take a "good" braking session to bed in anyways, especially if you've put new pads/shoes onto old dics/drums..... what flexible hos'es you used ? old or new ? braided ? old or even new unbraided hose can give a soft pedal......

IMO, the set up you have should pull you up no problem.......you have double the master cyls i have and i can stop on a sixpence.

I havn't tried them whilst moving yet.
My drive is on a steep slope, and a have to push the pedal quite hard in order to stop the car rolling.
I don't feel any resistance until the pedal is almost fully depressed.
I have got reconditioned calipers with new discs on the front, and new drums,shoes and cylinders on the back, all connected with new braided hose, where there needs to be flexibility.

It can take a long time to get all the air out of a brake system. Soft pedal nearly always means air and more bleeding. Quite often the speed with which the assistant floors the pedal can have an effect, a good swoosh being more likely to get the air than a slow pump. I once came across a brake cylinder that had been mounted in such a way that the bleed valve was at the bottom, worth checking for that stuff to.

Have you tried puimping the pedal several times,if the brakes firm up then it suggests maybe no bleeding required but one of the brake components is having to move too far, have you checked the brake lining adjustment?

i tend too (when bleeding / filling a new system for 1st time) never touch the pedal, just open all the bleed nipples and keep the res topped up, they will bleed themselves, as above, sounds very muchy like you still got air in there, with no servo your pedal should be like a rock.....
