Typically the activation of the ABS system is not required when flushing the brake fluid. The brake fluid in the ABS system is in a pristine environment unless the ABS system has an issue.I've read here that some vehicles you need a device to activate the ABS to flush the fluid.
Maybe the ABS is slowing down your flow.
If that's the case, consider yourself lucky that you can at least DIY.
On my Infiniti (Nissan), the FSM says to disconnect the ABS module's electrical connection when bleeding the brakes. I suspect the ABS system is something like a Bosch or some vendor vs an in-house Nissan so this procedure probably applies to many vehicles too.Typically the activation of the ABS system is not required when flushing the brake fluid.
I'd be interested in an answer to this too. Everybody talks about how great these things are, but nobody seems to have a clue when it doesn't work the way you want.I have tried using my Motive pressure bleeder several times on a 2003 Honda Element and 2001 Honda Accord with no success. It will seal and pressurize up to 15 psi, but barely dribbles out a teaspoon of brake fluid out the bleeder valve in a minute. It is quicker to gravity bleed it or have a helper press on the brake pedal while I open the bleeder screw. Is there something I am missing on these Hondas? Both have ABS brakes and it almost seems like the modulating valve is not allowing fluid to flow. Do Hondas need a bi-directional scanner to cycle the ABS valve open when flushing? Others on the Honda forums indicate they had success using the Motive bleeder. TIA for any advice.
BMW’s per manufacturer procedure should be bled using ABS pump (activated by INPA software). I do sometimes that and sometimes I use pressure bleeder. So, I wouldn’t think reason for slower rate is that.I have tried using my Motive pressure bleeder several times on a 2003 Honda Element and 2001 Honda Accord with no success.
