Hi all
Today I was preparing my 1997 90 series for a weekend offroad trip. I thought I'd adjust the lspv as I have OME and havent adjusted it before.
To make a long story short, I adjusted as much as I could, and tried braking hard on my driveway. Worked great, locked up all four wheels at the same time.
But, at the next normal braking, the pedal just went almost all the way. Turned out that I had two rusted brake lines, above the rear shocks on the left side. The hard braking blew one of them!:whoops:
I rushed of and got a few meters of brake tubing and replaced both the rusted brake lines. I had to remove the lspv to get to the line on top of it.
Anyway, put it all back together again, and bled both rear wheels and the valve itself, lots of air came and then it seemed to be okay.
But something is wrong, when pumping the pedal with the engine off (3.0td) the pedal seems firm and nice, but when I start it goes all mushy on me. It is very soft, and also if I pump it a couple of times it sinks slowly.
I have used a couple of litres of brake fluid, i have bled everywhere, at the end also at all connections at the master cylinder, carefully at the ABS unit (while holding pedal pressure), and it looked like I found small amounts of air at several places. But not better brakes.
I get clean brake fluid everywhere I try.
I suspected that maybe the ls valve is acting up on me, as i had to remove it and put it in a vise to get the brake line fitting off. But still I cant see why. The last thing I did tonight was pulling off the rubber boot on the valve, I could see a bit of rust and the little needle thing was stuck. Got it moving again, and also sprayed a little wd40 inside. Seemed to move freely after that.
I tried to open the bleed screw (did not pump) to see what came out, looked like clean brake fluid with no air.
I am leaving tomorrow morning, so I'm really in a bind here. I tried searching, and it seems like I'm not the only one with these issues, but I didn't find a good solution.
Lots of thanks for any ideas!
Stefan
