What the hell is up with the friggin ad pop-ups all over this forum? Good grief..

Anyway. I haven't had the availability of an assistant (certainly not one who will spend the time necessary to help me bleed the brakes) hence the Motiv.

The damn thing always over fills the master cylinder too; when I disconnect the brake bleeder, it has filled the reservoir to the top, and I have to siphon off fluid to level. PIA.

So you think getting someone to pump the brakes will help? How long does formerly fresh fluid stay fresh? I have gone through probably 64 ounces of brake fluid for this little fiasco, and I still have probably 24 oz level ieft in the Motiv which is less then 18 hours old. Any thoughts?

I will look up on YouTube how to bleed brakes with two people; unless you have a link to a good source?

I want to take these tires off again like I want a hole in my head. My back is spitting up blood at this point.

I recently changed out all my rotors/pads and rebuilt the passenger rear caliper because the dust boot was ripped. I did bleed that caliper and had my 7 year old son pump the brake.


Anyway, I have a spongy brake pedal too (even before this brake work) and my truck is 11 years old. I plan to have the dealer flush the brake system and refill, and I believe they have some specialty tools/equipment to deal with the ABS module.


I'm not sure if you need to go that route, but IMO I rather spend the money to get the system flushed and refilled completely including the ABS module than keep bleeding the brakes only getting out 25% of the fluid if that.

I have bled and flushed this 2005 before without issue? ABS hasnt been a problem before?

I was just reading online (and my Haynes manual) that says that a complete brake system flush requires the dealer equipment. Something about the dealer having some special computer that hooks up to the ABS system and cycles some valves as well as using a forced "power flush" of the entire brake system.


Also my brake fluid being 11 years old, I just want 100% all new fluid in there.

Prof

Whoa, I need this verified...I will not pay dealer prices for a simple brake bleed. Surely, if this is the case, a mom and pop could do it too?

ReaperHWK

Not sure, if your just doing a brake bleed you surely don't need the dealer and power flush/fill of the entire brake system.


I want to replace and flush ALL THE FLUID out of the system(including the ABS), so therefore, I'm going to pay the dealer to do that. My fluid is pretty brown compared to the new fluid. Plus I don't want to deal with all this fluid around my garage I need to dispose of.

You shouldn't have a problem with the ABS unless you changed out the Master Cylinder....which you haven't. When i bleed the brakes in my car just recently, i bleed the first rear wheel until i got new fluid into it (all the while making sure not to let the MC run low)

that pump your using its a vacuum pump right? It sucks the fluid out through the bleeder valve? I'm confused how a vacuum on the bleeder would cause your MC to over flow...your MC is suppose to drain as you pull fluid through the bleeder.

Prof

Bleeder. It is a pressure bleeder, but it doesn't pull from the bleeder valves, it pushes from the master; there is a tank which is connected to the master cylinder (tightly). You put fluid in the tank, and pressurize it...think the sprayer bottles you spread liquid insecticide on your roses. Then when you crack the valve at the caliper, the pressure pushes fluid out, and sucks it out of the tank into the master.

Now I read elsewhere of a guy who just does it dry, builds up pressure, and bleeds making sure that the master doesn't get too low. All in all, there is not a lot of fluid exchange, either way.

I figured out what I did wrong. Bonehead move. All better now.
