[DML] Re: D Brakes

["byrondelorean" <celiambyron@xxxxxxx>]

Thanks for the couple replies I have recieved. All very interesting 
as it does open up some other areas to look. I will have to give 
Dave a call and run down the list of questions. 
In a pnic stop the car will stop. There is no pulling in either 
direction when you apply the barkes. I get a lot of brake pad 
clatter when driving on bumpy pavement even with Rob Grady's spring 
and cotter assembly. I never recall this especially when weI had a 
gravel driveway growing up with the car. Always smooth and quiet, 
soemtimes alittle brake squeal. The problem in a panic stop is that 
that the second longer it takes me to get to the brake actually 
doing anything may be the second I need to prevent an accident. This 
is my main concern of course.
