[urq] brake pedal feel

Correct, but I'm still not convinced the 'new' BMW bomb was good to begin 
with or my valveblock is at fault. I should have swap back my old AUDI bomb 
for the BMW's just for testing but I could not be bothered. I also have a 
spare valveblock, still unpacked for the same reasons. In the meantime, my 
problem today is exactly like you discribe, including the cyclic ticking 
noise on hold. I'm used to it now, but if I ever have to make a full 
emergency stop, those 2 seconds could be fatal. Oh well.

Perhaps the combination of the G60 with my pre-G60 brake master cylinder 
(although brand new) causes this delayed feeling. If you think about it, it 
does make sense: the extra 2 pots in the G60 need extra volume/fluid which 
could not be pushed by the original BMC. I'm still confused today why I did 
not buy the newer style BMC to match the G60s... :stupid:

>> Gentlemen,

I developed this same problem at the track over the weekend.  Keith
describes it to the 'T' with, "If you stand on the pedal hard the
pedal feel is hard with very little braking effect but if you stay on
it (maintain the pressure) the full assistance comes in and the brakes
suddenly work well."  Needless to say, coming into turn 9 at Bremerton
Raceway was disconcerting. I'd deal with it like turbo lag, get on the
brakes a beat or two before I actually wanted them to kick in.  Kinda
creepy.

Keith, did you ever fix it?  Maurits, did you say replacing the bomb
did not help?  My valve block beneath the bomb has leaked slightly
since the day I got the car, it's a crusty nasty mess.  I did used to
notice that cyclical clicking noise when I would hold the brakes on at
a stop light. I'll have to pay attention and see if that's still
happening now that I've developed this problem.

Thanks,
Rich
