hi iv got a impreza 2ltr sport iv just changed the front brake from 1 pot to 2 pot brakes iv bled the brake all round and still i got no brakes as first pump but on the second they r there what can this be iv been told it could be the flexi brake pipe has colapsed ??

 

Air.

 

I had this problem to find out that I had the bleed nipple the wrong way around...make sure it's pointing at the top and not the bottom

 

The bleed nipple needs to be at the top mate as air is lighter than fluid so the nipple being at the top will release it

 

As Addi said, when i went from 2 pots to 4 pots, i had the same issue and it was due to calipers being on the wrong sides and the nipples need to be at the top

 

I stand corrected , I thought it was bottom got mixed up a little there lol
