they need re-bled, or new pads, or those pads need used to weaR IN TO THE WORN DISC
HOW MANY TIMES HAS HE TRIED TO USE THEM ?
sorry bout the caps lock, not retyping
remove rezzie lid, keep full of fluid at all time
take the caliper off, flip it upside down to face the bleeders up, pump pedal then hold down, crack bleeder, tighten bleeder, release pedal, until no air is seen coming out
these brakes should work, locking up the brakes with one finger pressure, pushing the pedal harder does nothing to a hydro system
if re-bleeding doesnt work, i'll get back to you when i return from oconnors on tuesday
