The brakes on my '95 FZJ80 were a tad mushy, so I thought I'd bleed and see what happens....
I spent half the day yesterday and half the day today bleeding...and bleeding...and bleeding. I've got the clearest and cleanest brake fluid I've ever seen, but not only do I still have mushy brakes, now I have brakes that go almost (although not quite) to the floor, when the engine is turned on. With the engine off, the pedal feels OK, although when I really stand it, it's pretty low. I'm pretty sure it's not drivable at this point. However, it was perfectly drivable before I started messing with bleeding the darn things.
I've followed the FSM to the letter again, and again. Even did the master cylinder several times. At this point, I'm wondering if my master cylinder was going bad and bleeding the brakes just caused it to go over the edge somehow or if I just need to keep bleeding, because I still have air in the system.
I'd certainly appreciate any insight as to why it is so difficult to get air out of the system, compared to other rigs, assuming that's my problem. I thought maybe the ABS was trapping air, but I've read this problem is occures on the FJ80s too. My other theory is that some how the return line from the LSVP is trapping air and not letting it out.
The FSM says to "bleed the by-pass pipe", but makes no mention of what exactly that is. I'm guessing they are referring to the LSVP, which I've definately bleed over and over again. But I would sure love to know if they mean something else and I'm missing something.
