gents,
got a soft brake situation i could use some feedback on. i recently did a disc conversion up front on my 65 valiant and i can't get that good bite. whatcha think?
installed:
Scarebird conversion kit (front only)
single piston calipers
new master cylinder and 7" power booster with vacuum from intake manifold
new 3/16 tubing from disc/drum prop valve directly to front flex hoses
10lb residual valve to rears
I bench bled the master cylinder and have now bled the system 4 times. No leaks, no bubbles.
If i give it a lot of leg i can get the rears to lock up but that's full on pressing as hard as i can.
under full brake effort the thing stays perfectly straight too. no pulling either way
but i don't feel any nose dive at all.
wrong prop valve? should i get rid of the prop valve?
thanks in advance for your thoughts.
