I have never done this before. Is there anything i need to know before doing this? I think i saw mr 5 post the flushing order of:

Pass Rear
Driver Rear
Pass Front
Driver Front

i know i need 2 ppl to flush the brakes. I just wonder if theres any DIY or instrutions anywhere. Id like to get this done for the track meet this weekend .

You should use a pressure bleeder when possible. There is no need to follow the above order when a pressure bleeder is used.

I used a pressure bleeder and followed the above order anyway, just out of habit. Also, use a turkey baster or siphon to get the old fluid out of the reservoir, just so it's less fluid to pump through the system.

So this is probably late but here goes.
The sequence is correct becuase you want to bleed the longest line first and the second longest line second etc.

I like the two-person method (gives my wife something to do - she's really good at it now after 20 years or so). So get a small jar fill it a bit with clean brake fluid. Suck out the old fluid in the reservoir, add new fluid. Have your partner in the car with foot on the brake. Attach a clear hose to the bleed screw on the caliper and put the end into a jar with brake fluid in it to keep air fromt getting back up the line. Crack open the bleed screw as your partnner lightly pushes on the brake pedal. As the pedal sinks close the bleed screw. Don't have your partner bottomout the pedal, it damages the master cylinder. Have your partner repeat as you open the bleed screw. Do it until clear brake fluid without bubbles in it is running through the hose. Repeat procedure for all four brakes.

Sorry to resurrect an old thread, but...

I flushed my brakes and suspect there is still an air bubble floating around in the system.

I've read on another forum that BMW recommends activating the DTC/DSC when bleeding. This sort of makes sense since traction control is clearly integrated with the braking system, and there may be an isolated hydraulic circuit under the control of DTC/DSC. However, I don't see any activation/command for DTC/DSC with my BavTech software.

Anyone heard of this before? From the comments above it seems nobody worries about DTC/DSC when they flush their brakes.

DTC/DSC doesn't affect the bleeding procedure.

The start at the back (longest line) technically doesn't apply with ABS, since the lines are all independant after the ABS module. That theory applies to cars without ABS.

If you think there is air in the system - go to a shop and just spend the $80 to get it pressure bled (or spend $50 and get your own pressure bleader tool).

Was wondering how much bubbles are normally seen coming out of the valves..? And how much old fluid is collected per corner..? I've used the motive bleeder twice and I see lots of bubbles coming out of valves..almost like bubbles you see when you pour water from a bottle.. My question is that are these bubbles really from the lines or from around the neck of the bleeder valves?? I do track my car often. I use Ate blue alternating with yellow.
