Brake fluid bleeding sequence

[james250]

Does anyone know the correct brake fluid bleeding/draining sequence. Many places I read to start furtherst away from fluid reservoir but some say to start from closest. From furthest I would think in this order: back drivers, back passengers, front drivers and finally front passengers 

Also when using a suction tool to remove some old fluid from the reservoir. I am assuming we should remove small amount not allowing it to drop to the hose as this can allow air to enter the lines right?

I don't think it matters with modern cars. The lines all run directly back to the actuator.

Sucking out the old fluid shouldn't introduce air I would think. Just top it up after. That's what I did anyway. 

You will notice air in the system very quickly.

Back when we had more simplistic vehicles, I was a Tech (1970 to 1980), we were always taught to start at the furthest bleed valve from the servo / reservoir. I agree that with dual line systems and all the safety features existing it may not be massively detrimental ,but always keep the reservoir topped up, air is the system is not desirable!   Take your time if you're doing the job solo and check and check again that you are using the appropriate DOT ? Fluid for your your vehicle. Its been a while , happy to hear more uptodate advice myself from the more experienced modern techs.

The workshop manual does say to start at the wheel furthest from the master cylinder - which is of course the rear passenger side, then rear drivers side, front passenger side, finally front drivers side. Not sure why you think the passenger side wheels are closer to the master cylinder than the drivers!

Just keep an eye on the master cylinder reservoir to make sure it does not drop too low otherwise you're gonna kick yourself if you entrain any air in the system and end up taking twice as long to do the job and use twice as much fluid!
