[s-cars] Clunk

[matt ludwig]

Hey Mr. Myers,

any chance there is a buildup on a rotor from one of those 'major brake 
checks'? probably too obvious a question as it would do it at almost 
all speeds i imagine, or would pulsate at the least. just a thought 
though.

maybe a 'disrupted' brake pad from that recent big brake upgrade you 
did? don't know if those pads can shift that much in those mono-blocks, 
but at a slow speed stop one has a tendency to let pressure off the 
pedal just enough where something down-stream may be able to settle or 
something resulting in the "clunk". don't know and am probably way off 
here.

sincerely,

matt ludwig.
