q45 brakes upgrade gone bad...

[Brandon8965]

so i install the calipers, rotors, pads etc.. i've done all the modification work..i bled the system regularly and i did the whole gravity bleeding.. in the end i have about 3% of the pedal pressure i had before.. everything worked perfectly before i did this.

PLEASE HELP!

hmm the MC is about the same size as the Q MC, so that shouldnt be an issue..

Ive worked alot with Q brakes and last time I did Q brakes I accidentally got air in the MC from letting the fluid get down too low.. Try bleeding the MC, then do all 4 corners again... Make sure the MC is really good and bled otherwise youll just waste time..

I dont really believe in that gravity bleeding...

[Brandon8965]

yea i'm bout to go out there and try to bench bleed it... and yes gravity bleeding is a big messy waste of time

[elwesso]

I really think bench bleeding is a waste too, because you still have to open it up to put it back on the car...

Just open the bleeder on the MC, and it should only take a couple pumps to get all the air out of it...

also, for ABS cars remember that the ABS actuator acts like the MC, so if the ABS thing is on the passenger side, you need to go drivers rear, pass rear, drivers front, pass front...

ok so this is gonna be noobish of me but where would this MC bleeder be

[elwesso]

Well nissan uses 2 kinds of MC's, the NABCO and TOKICO...

Usually the NABCO ones have a bleeder right on the side, that looks like the regular bleeders that are on the calipers... Ive seen the tokico's that dont have them, in which case you're kinda screwed, but on every car ive seen with a tokico MC the ABS actuator has a bleeder on it, which is just as good...

[Brandon8965]

mine is NABCO... i see a screw on the very bottom but nothin looks like a regular bleeder screw... all the rest is just the lines into the cylinder... also i don't believe that i have abs at all but where would such actuator be located

[Brandon8965]

nevermind that wasn't a screw at all.. and i don't have abs at all
