I bleed another container of fluid through it this weekend. Took it to a local parking lot. Pedal still like a marshmallow, but if you pressed deep down, it would stop the car..
Did a bunch of panic stopps, getting the ABS pump going. But it just seemed like the rear brakes were not engaging at all..

Well, broke down and took it to the dealer this morning. Explained that I though there was air trapped in the ABS Pump and needed them to have the computer run the bleed sequence to get it out..
Hour and half later they brought it around. $143 dollars sir..
Drove it, somewhat, but not alot better than it was..
Went back in, asked if they test drove it..
Service advisor drove it, said felt fine to him..
Asked if they had cycled the ABS pump, he had no idea of course..
Took it to the shop foreman..
Another hour and half later, Advisor tells me they ran the 'bleed program' from the computer and asks me to test drive it..
Light years better. I'm still a little unhappy with the pedal feel overall, but at least all the brakes are working, and it is safe to drive again.
Hoping my experience is like "Ashaman", in that I've got a solid pedal engine off, but soft engine on

Day 4 I was able to properly pressurize the reservoir. I performed a full bleed, at each point I pressurized the reservoir, opened the bleeder. Allows the attached hose to fully fill, submerged in a container of brake fluid. Pumped the brakes 5 times. Ran the DIS bleed procedure. Pumped the brake 5 times. Started the engine, pumped the brake 5 times. Ran the DIS bleed procedure. Closed the bleeder. Sounds ridiculous; but I got a TON of air out of the system, mainly at the passenger rear.
So, after this raindance, I had a fairly firm pedal with the engine off, but it was still soft with the engine running. Hoping my pedal firms up too over the next few days, but not holding out a lot of hope.
The next day after work, I basically repeated the exact same process. Afterwards, I had a pedal that was rock solid with engine off, and usable with the engine running. I still didn't think it was quite as good as before, but at least I could drive it and bed the pads in.
Today I drove it to work, and they feel great. Not sure why it is any different than last night, maybe the fluid was a bit aerated; but they are fantastic now.
I sometimes like to check it after driving a few days to ensure no additional air worked its way back out of the system, so I'll probably do that this time too - but for the time being I am just happy to lay it to rest - What a fiasco!
You can be darned sure I'll watch fluid levels like a hawk the next service; that is for sure!
But yeah, pressure bleeding running the "Bleed Procedure" routine were key. It was difficult enough and took enough time even with them, I don't think it ever would have been possible without them. I suppose this is pretty typical of any modern AWD vehicle, but it was a frustrating bit O' learning for sure. Thanks again to everyone who helped! |
Thanks everyone for your feedback..
P.S. - Would be nice if you didn't have to
tell the dealership that there is a procedure to run on the computer to get the air out of the ABS pump..
