1999 Chevrolet C1500 Suburban 5.7L Brakes
Posted to GM Brakes on 9/21/2010 21 Replies

When coming to a stop at about 8 mph there is a thump noise and the brake pedal drops about a quater inch.

Does it in manual low so it is not a downshift concern. Does not happen in reverse or neutral only when in a forward gear. Thanks for the help.
