CHECK YOUR MASTER CYLINDER FLUID LEVEL---IF IT'S LOW LOOK FOR A LEAK

THE PEDAL COULD BE DROPPING FOR A COUPLE OR MORE OF REASONS

ONE BEING FLUID IS SQUIRTING OUT FROM SOMEWHERE IN THE SYSTEM

YET ANOTHER IS NOT BLEEDING THE SYSTEM CORRECTLY---LET ME KNOW IF YOU WANT MORE INFO

ANOTHER IS THE MASTER CYLINDER'S (BASICALLY A PISTON, PUSHING FLUID) SEALS ON THE PISTON INSIDE ARE ALLOWING FLUID TO BYPASS THEM----(SOMETIMES CALLED AN "INTERNAL LEAK.W/ NO FLUID LOSS). REPLACEMENT IS THE BETTER OPTION THAN ATTEMPTING TO REBUILD IT

SHOULD IT COME DOWN TO A DIY FIX AND YOU NEED TO PURCHASE ONE---LET ME KNOW--I CAN EXPLAIN HOW TO SAVE A BUNDLE
