Just like any other car. Without speedbleeders or a pressure-based pump, you need two people. Correct order is right rear, left rear, right front, left front. Vacuum pump bleeder kits don't work well at all. It helps to remove each bleeder screw and lube the threads with some heavy grease before doing the bleed (reduces the chance of air getting sucked back in).

Incorrect. Due to the location of the ABS box, the correct order for the FD is RR, LR, LF, RF. Remember: the order is based on the hydraulic circuit, not physical distance.

This is not what I've been told about our cars. I've been told to bleed furthest to closest to the master cylinder, not the abs unit, and in fact the FSM states to start air bleeding at the wheel furthest from the master cylinder (page P-7)

One detail I'm still unsure of is whether the ignition must be 'on' to see fluid move through the ABS box. I just do it to be safe.

I hate to be blunt, but you've been told wrong. Look again at page P-7 in the FSM. Upper left corner has a picture of the brake system with numbers next to each wheel. These numbers indicate the order in which to bleed, and it corresponds to what I stated above.

You need to think about the brake system in a hydraulic sense (ie, how far does the fluid have to travel). The fluid goes from the master cylinder to the ABS box on the passenger side. From there, it is distributed to all 4 wheels. The correct order of furthest from the master cyclinder to closest, is as I stated before: RR, LR, LF, RF.

Failsafe for the ABS box is all channels open. In other words: with the ignition "off," fluid will still flow to all 4 wheels through the box. But the key must be "on" in order for the ABS "pulsation" to engage.

I've snapped the picture from the PDF and added some color coded points. Red indicateds the bleed numbers, blue the MC location, and yellow the ABS unit




Course, I just went through all this and realized that I had mis-read your original post and thought for some reason you had typed RR, LR, RF, LF. Sorry for the confusion, but now we have a nice picture to help the thread starter

It would appear then I did my fronts in the wrong order. I could swear I checked the FSM, grr.

Nice photo job Section8! I'm sure that'll help many people out.

dgeesaman- don't feel bad, you're not the only one who has done this. I was used to old non-ABS cars, so it took me a long time to get used to the new order. Probably the first 5 times I bled the FD brakes, I would do it incorrectly, and have to go back and re-do the bleed job. At least now you know, so you won't make the same mistake twice!

Going with the two man system is the easiest way I think. The vaccum pumps don't work all that well.
