After you swap out the lines, this is the procedure.  If you have speed bleeders, you can skip some parts, but anyway...

1.  Connect clear plastic tube to bleed screw
2.  Drop tube into a container
3.  Check to make sure that fluid level in MC reservoir is good to go for now.
4.  Have someone pump the brake pedal until it is firm and then *hold* it there.
5.  You turn the bleed screw so it opens and fluid comes out.
6.  The pedal will fall...do NOT let it touch the floor...hold it about an inch off.
7.  Close bleed screw.
8.  Pump, open, bleed, close, repeat.
9.  Do that until the bubbles stop coming...make sure to check your reservoir a lot (leave the cap off, it's fine).
10. Go to the next brake...in the proper order, which IIRC is:

Left Rear
Right Rear
Right Front
Left Front

But that's TOTALLY different if you have ABS.  Oh, and I see you have an S14...ask someone who has an S14 with ABS about that.

#9 - Check it for what?  IIRC you don't want it to go dry, keep adding new fluid.

What happens if you do it in the wrong order?

I suspect it won't bleed completly and the overall process will take longer.

For s14/w abs on the top of the ABS module in the engine compartment are two star shaped bolts. After bleeding all calipers one must bleed each of those bolts.

However in the 3 times I've bled my brakes (add one cause I'm waiting for some ss lines also) I've never had to bleed those top bolts.

Why don't you let the pedal touch the floor? &nbsp;Just wondering...

For those of you with the 1993 S13s,the bleeding order is DIFFERENT. I'm not sure if this is for all "1.5 generation" S13s (1991 - 1994), or if it's just 1993 but I'm pretty sure of its accuracy re: 1993 Coupe and Hatch models.

My 1993 FSM states that for BOTH ABS and non-ABS models, you should bleed them in the order:

Left Rear
Right Rear
Left Front
Right Front

For ABS models, you also bleed (in this order, after the above):

Front side air bleeder on ABS actuator
Rear side air bleeder on ABS actuator


Just chipping in my share. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/thumbs-up.gif" border="0" valign="absmiddle" alt=':thumbsup:'>

You don't let the pedal hit the floor cause it can suck fluid(and air) back in then system. Also if you are bleeding the lines after installing your brake lines...
(Helps to have 2 people for any bleeding)
1. Check fluid in MC resevoir.
2. Open bleeder and press brake.
3. Close the bleeder before the person pressing the brake fully pressed the brake.(GOOD COMMUNICATION)
4. Check MC reservoir fluid again and repeat on all wheels.

You will have to bleed it the normal way afterwards but this will save time if you have emptied the system. This will also use more brake fluid as you will be pushing out a lot when you press the pedal. Never use the fluid you bleed out in your brake system again.

YOU WILL HAVE TO BLEED YOUR SYSTEM THE CONVENTIONAL WAY AGAIN AFTER THIS!(Look up for it)

::TIP:: You can use a wrench to tap calipers and it will help to get little bubbles of air free from crevices and such.

I always bleed them in an X. i.e. right rear, left front, left rear, right front. I have sn s14. Not sure if that was the correct way to do it?
