alignment done but, brake prop valve bad??? Options

[MarkG]

Well, my $831.76 alignment is done, will be picking car up this afternoon. They had to tap the tie rod ends to get enough toe. Something is not right here .....

I still think its because of the way I incorrectly placed the bump steer spacers (I lowered the cross member rather than raising the steering rack) created a distance issue from the tie rod to the A-arm/strut, but shop believes the turbo tie rods were not threaded deep enough........

Asked them to bleed my brakes as my pedal has about 3-4" travel after I added 19mm m/c and rebuilt front calipers and replaced hoses.

They tell me the brake proportioning valve is bad.....they can hear it click which they say indicates it's bad. They were unable to help with the mushy pedal (I don't believe they bled the valve).

Soooooo..do these go bad or should I try bleeding it before replacing it (with V.W. Tee fitting....)?
