5 stud brake conversion soft brakes

[jayeg]

just done a 5 lug conversion bled the system fluid coming out all the calipers the handbrake is fine but the brakes only work when the car is off when i turn the car on the brakes go al the way to the floor and it still brakes just a bit i checkd the passenger side caliper when i took it off all the brake fluid leak out without me pushing the piston back in any help would be great im thinkig it might be the seal and its not the booster it was fine before the swap

did you swap bmc? sounds like wasnt bled properly.
bmc need to be bench bleed before install

[jayeg]

i didnt no that i didnt bleed bmc

[IEVAQ8]

either ur prop valve needs to be changed, or it may sound dumb, but i had the same issue and i opened all the bleed nipples with hoses and bottles attached to each one and let them gravity bleed...

then i did another normal bleed and it was spot on

[jayeg]

so it might not be the calipers thanks i will try that

[ECU-MAN]

did you change the master cylinder ????

[EG5]

Did you install 1 way valve the right way ?
Did you change your master cylinder and brake booster into 1 inch ?

[jayeg]

i didnt change master cylinder or install 1 way valve jax tyres told me the standard stuff should do the trick so im need to change that stuff over would crv parts work

[ECU-MAN]

that is why you have a long pedal, the Stock BMC wont cut it,

[jayeg]

so should i just try replacing the bmc first then see how that goes
