Bleeding the master cylinder, ABS
I won't get into why, but the brake fluid completely drained out of my master cylinder and abs. I am going to bench bleed the master cylinder before putting it back on. Where can I get the adapters and tubing to do this? Would they have some kind of kit at AutoZone?
Also, is there any kind of special bleeding procedures for the ABS? I looked through the FSM, but it didn't mention anything other than regular line bleeding. |
Most autoparts places will have a universal bench bleeding kit that consists of some plastic adaptors and a few short lengths of tubing. Ask them at the counter.
No special bleeding procedure for the ABS on this car. |
Just bringing this back from the dead...
I've purchased a new ABS module.. just wondering is there some sort of bench bleeding procedure, or any need to cycle the valves etc when bleeding the new unit before or once fitted? |
Just a quick update/FYI.. the new ABS unit seems to be bench bled already from the factory, with screw in plastic stops to seal the line connections on the unit.

The plastic caps are just to keep debris/junk out. I don't think it's pre-bled as it doesn't come with fluid in it.
It's really simple to do, basically all I do is, make sure fluid comes out of all the holes (master cyl), and that's usually good enough. (You don't want tiny airbubbles in the MC). |
Thanks ehos, however, I was referring to the ABS unit, not the MC.

The plastic caps serve the same purpose on the new ABS unit, they're just there to keep dirt and dust from entering. There's no way that plastic screw-in caps will seal properly during shipping and warehousing, and it's expensive to ship a device that contains hydraulic fluid.

Doesn't the FSM detail bleeding the ABS somewhere in the ABS procedures? It certainly should. I recall something like turning the ignition on to open the valves. With the ignition off the ABS remains isolated and bleeding won't move any air/fluid thru it. Dave |
