[DML] Re: Front breaks not working

["Harold McElraft" <hmcelraft@xxxxxxx>]

You are sure all the air is out of the rear brakes? You replaced the 
flex brake lines? Air and fluid may not give the same results in an 
internally damaged flex brake line. Also, very important, did you 
bench bleed the master cylinder before you put it on?
