Hi all,
First time post here on the boards.
Probably asked and answered a thousand times, and I've searched the threads and found about a dozen different answers, but feel free to flame away anyway (and then help out if you can).
New to me, 2000 D2 with soft, almost squishy brakes. Not all the way to the floor, and decent stopping power, but definitely much less travel and more pressure on second pump. Recently had all four wheels off and checked pads: all four wheels have new pads, and none of the wheel cylinders show any signs of leaks. Although I didn't mic the rotors, there doesn't appear to be any grooving or a defined edge that would indicate excessive wear. Also, no signs of any leaks at the MC, and it's not eating fluid.
Did two bleeds: one following the RAVE process, including sequence, and another using the traditional "pump and hold" method. I did manage to get some air out of the system, especially at the first (front right) wheel I bled. Maybe a slight improvement, but still not what I'd expect/hope for. Also inspected lines for any bulging or damage and none visible, even when applying pedal.
I've heard of internal seal failures at the MC that allows blow-by, but no resulting leaks. Is this my next step? New MC, bench-bled, then a complete re-bleed of the system? I didn't see anything in the RAVE regarding any bleeding specific to the ABS, but I know some vehicles do have a bleed valve on the modulator as well.
Thanks,
