Ok, I just got done replacing the right rear inner axle seal on my Runner. I finished up and blead the brakes then topped off the fluid, but now my brakes are spongy. I did a search and couldn't find what could be the problem. I blead them again to make absolutly sure there was no air in the line, but they are still spongy and I've kinda run out of ideas. What do you think?

 

What did you bleed and in what order?

 

I don't know about the 96 but my 95 has a load sensing proportioning valve. On mine this is located above the rear axle just to the right of the diff. After I bled mine, my brakes were much improved.

 

I bled the right rear only, because that is the only line I disconnected, and after reading all the write-ups that is all that was called for. I know if I bleed the whole system, to start at the wheel farthest from the master cylinder and work your way around, but from the write-ups I read; it said you only had to bleed the line you disconnected.

 

Air from one line can rise up and get into the rest of the system, they all share fluid to some extent. Bleed all 4 wheels *and* the LSPV, farthest to nearest.

And I think your initial question about needing to do all the fittings if you only touch one line is answered by the fact you have spongy brakes after bleeding only one line.

 

Bleed them all. That should take care of the problem. Depending on how much fluid you lost there could be air in the other rear side now. And heck......it only takes a few minutes to do the fronts While your at it, you might as well just flush the old brake fluid out and replace it all.

 

Yeah that's what I figured, I'll try that tomorrow. Thanks guys.

 

The 3rd Gen's with ABS don't have the LSPV, but the non ABS ones do.
