hey wasup guys need some help i installed the 13" cobra and 300zx calipers put the stainless steel lines also after all thats i started bleeding the brake line after i finished the pedal feels like **** and falls to the floor so i bleed all the lines from front to back and it still feels the same

 

First thing to check is if the bleeder screw is on top of the caliper. If not then they are on the wrong corner of the car.

 

I believe youre supposed to start with the caliper furthest away from the resevoir (passenger side Rear) and work your way up front to the driverside front. that's probably why it's so spongy and terrible.

 

+1.

You bleed:

RR
RL
FR
FL

 

ok will try to bleeding it for the far rear to the front and see how it feels i want to now how does the conversation compare to the stock

 

1. make sure you're not ghettoing out and using banjo bolt brake lines.
2. check for leaks on all fittings you touched during the conversion.
3. look for brake fluid leaking form the caliper piston seals, body, and bleeder screw.
4. bleed again (any order you want- doesn't make that much difference) making sure you keep the master cylinder full and bleed ALL the air from the system.

if you have ABS, check the manual to make sure you're doing it right. I forget if the engine has to be on/off/ign on or whatever to bleed a system with ABS. make sure you're doing that, as it's critical with an ABS car.

 

Thats how I bleed my car but read somewhere it was


rr
lf
lr
rf

Did I read it wrong? Also read is car to be off.

 

You want the bleed furthest from the master cylinder to the closest last.

RR is correct
LF is the closest unfortunately. So that's the wrong order.

 

Cool atleast I did it the right way but I guess read it wrong.

 

i bleed the brakes over again from rr/lr/rf/lf and my pedal is still spongy what could be the problem the master

 

You need to read Matt's post. He knows his ****:

 

If you just change the calipers, you don't have to bleed the entire car (assuming you didin't let the M/C fluid level drop below the minimum...

In any case, you definitely need to bleed it more. Also make sure to pump the pedal a few times with the car off to bleed air out of the ABS system (also pull ABS fuse when you do this).
