using a 120y booster in a 1200 ute
i bought brand new
master
rear slaves in drums
new lines
all installed and no leaks etc

i bled the master and front and rear but still no breaks and pedal is not hard still.

my questions are

how many cycles do you have to do before you start getting hard pedal and breaks

ive done 2 3 cycles and still nothing

also any tricks or hot tips


when i bled clutch i only done 2 3 times and it hardened up and works great

Ok where do i start?

Start bleeding the breaks furthest from the master to the closest. So RL, RR, FL, FR.

To bleed get a mate to help you. Get him in the car operation the pedal. get him to pump it thru untill no more air comes out the bleeder. Then get him to hold the pedal down. tighten the nipple. get him to pump it up 3 times and hold down. open the nipple. close the nipple. do this till no air spits out with the brake fluid. Do this at every wheel and both outlets for the master by just cracking the line.

If you are positive you have no air in the brakes, try adjusting your drums up.

If the air keeps comin like it happened to me...then your problem is in your brake master cilinder...mine had this problem...kept pumping and the air bubbles didnt stop...took the master cilinder apart and put some new ruber O-rings or whatever you call them...

thanks guys

everything is new so i am asuming no leaks


ill try beatie way tomorrow

any idea how many times i have to do this before i start getting a firm pedal

and how is the rod usualy set up on the pedal with spacer like madat and stock 120y spacer

i adjusted as far in on thread as possible and adjusted pedal stop/break light switch out
i havent adjusted in yet so there is a bit of tention there but i can adjust in more as the pedal dont hit the floor yet by about 10mm but this will cause more tention on rod with no load

i plan to bleed breaks and if it dont work i might adjust in more
