I recently converted my non brembo 350z to a brembo. I can't seem to get the air out of the brake system. I used the RL FR RR FF sequence to bleed them but no matter how many times i bled it, air pocket keep coming back. a strange thing i noticed: after i bleed the inside caliper (until no more air), then i move to the outside (until no more air) however when i move back to the inside caliper again a crap load of air comes out every single time. i have checked for leaks and can't find any... the car has no braking problems besides for the slightly mooshy brakes. Anyone have any suggestions on what i should try next? any help would be appreciated.

 

have someone pump the brakes ten times then bleed. Repeat that step three times. You should be golden afterwards.

 

For bleeding, after losening the nipple and you can see fluid bubbling, after the bubbling is gone you can see the bubble-less fluid coming out. Thats when I attached the transparent tube to fit over the nipple and pumped about 10 times to get any remaining air out.
Then if you dont see any air in the tube, then you are done. Follow the same for all calipers.

Hope this helps.

 

make sure when your friend is pumping the breaks to get the air out, you close the nipple while he is stepping downward on the brakes, or else if u close the nipple while the brakes is coming back up, it'll suck in air from the nipple right before you close it..

Now go bleed before I make you bleed... lol jk

 

alright thanks guys

 

hhhahahaa, i was just about to post this exact thing!!! i just put on new brake lines and bbk from racingbrake..and i can't get the air out either!!!
did everything all you guys suggested...i'll be driving over to speedlab tomorrow morning to get some help from them...at least i installed the kit myself!

 

didn't work?

 

nope, response improved, but cant seem to get all the air out...any tips are greatly appreciated...i assume i just need to repeat the process several more times

 

seal it after the the 3rd set on the 10th time when theres no more bubbles and the person is holding down the breaks ALLLLLL the way down. I mean to the metal.

 

"seal it"..you mean close the bleeder valve?...and does the perosn holding down the brakes push the pedal once, then bleed...close...again, bleed, close...x10...or is it better to pump the brakes 5 times,build pressure, then hold down on the 5th pedal depress?

 

Well you open the valve, pump it ten times. On the tenth time hold it down the to floor. There shouldnt be much air left if any. Seal it off. Then repeat again for a total of 3 times. Worked like a charm for me

 

keep the valve open as u pump it the 10 times?!?!?! wouldnt this suck air in everytime the pedal comes up?

 

My bad I'm sorry. Closed first while pumping the ten times. It should get the air up to the top. Then on the tenth, have the person press hard and hold all the way down. Then open. They'll feel the brake go all the way down. Then seal. Then repeat two more times. Sorry I'm tired as hell

 

Make sure "pedal boy" lifts his foot slowly (count to 5 at least). Otherwise, the fluid might foam.

Also, leaving the car for rest over night will have helped.

I hope your brake lines don't make any loop where air can get stuck?

 

Pedal Boy: pump brakes till pedal is stiff (nipple closed)
Pedal Boy: keep brake pedal pressed all the way down. (nipple closed)
Bleeder: Open nipple while pedal is all the way down.

(pedal boy's pedal will sink more)
after the nipple stops squirting brake fluid

Bleeder: close nipple right away.
Pedal Boy; depress the pedal

---repeat process for a couple times till brake fluid squirts out in a smooth fluid like fashion, if the fluid is still squrting out in pulses, air is still present---

did i miss something guys?

 

isnt it suposed to be:

LR LL FR FL

?

 

ok, following all of the above advice, brody pointed it out to me this morning...the 6 piston caliper has two bleeders, i was only bleeding one of them, air was trapped in there... bled both..they work great now..write up coming soon

TODD

 

You deserve some ***** slapping for that one ! Haha!

Glad all is well now

 

hahaha..hell ya, felt like an idiot..live and learn
