I've searched and cannot find a definitive answer on the brake bleeding order and procedure for the s14 w/ ABS.

I've found that people have mentioned to start with:
#1
Passenger Rear
Driver Rear
Passenger Front
Driver Front

Than I found:
#2
Driver Rear
Passenger Rear
Driver Front
Passenger Front

#3
Than I found that people bleed 2 star screws on the ABS module.

Which do I use to bleed my S14 w/ ABS?

#1? #2? #1? #2?

Thanks guys I just want some sanity

Maybe Russ could chime in?

ABS brake bleeding on ABS cars are the same as any other car. RR,LR,RF,LF. The only reason people say you may need to bled the pump is not all ABS pump are designed the same. When you bleed the brakes with the car off, the pump isnt on.

The best way to do it is to bleed it once and then go out and make some sudden hard stops to initiate the ABS. This gets the fluid worked through the pump. After that, go bleed it again. This will get all the dirty fluid out.

I have an ABS car and have always done it like any other brake system. Never had a problem with it.

Yeah....I have a question too about the ABS....I know you can bleed the ABS using the 2 TORX screws on top of the unit, but where does the fluid come out?

I didn't see a bleed nut or somewhere to put a hose on....does the fluid just pour out the top hahah?

It's Right Rear, Left Rear, Right Front, Left Front for all 240's. ABS you just pull the connectors on the ABS module to make sure the solenoid's release(or pull the batt ground).

I always learned that you start farthest away from your BMC and that would be passenger rear.

Yah it's different for ABS because of how the hardlines run, the lengths are different than they would be with no ABS

No, It's not. Get an FSM. I have one on the shelf next to me. Only thing you have to do is disable the abs module.

Bingo. Unplug the actuator and bleed as normal. I've never had to bleed the actuator itself.

Actually, on S-chassis, the left rear is farther from the MC than the right rear because of the way the lines are run. (USDM)
