ke30 Brake booster...

[lorolla24]

Hi,

Not sure if the booster is stuffed.
I have changed to nissan 4 pots front and toyota disc's on the back. Using a Pajero 1" master cylinder.

Seems to have a nice hard pedal but I have to push really really hard to get it to stop.
Feels like there is NO assistance from the booster.

Done some checks and it seems to have vacuum to it. If you start the engine with the brakes pressed it goes down, but only i little bit.

Anybody had this issue with this upgrade or similar?
Is the booster to small?
Anybody got a booster reconditioned? Did it help.
