front brakes "pulsing" under hard breaking

raven41

Another low tech (but cheap) idea would be to go over both sides of the brake disc with some sort of light abrasive material. If there is any residue clinging to the surface of the disc this could remove it. If part of the disc is contaminated every time this bit goes throughout the caliper it will cause it to " slip " giving the impression of a warped disc.
I use a kitchen scourer or some very fine grain sand paper
Worth a try....

Why would you think a kitchen scourer would remove what a brake pad can't???

Brake pads aren't designed to be abrasive, they use a blend of material to create friction without wearing the discs down too fast.
Light sandpaper will remove the surface of the disc and any deposited material without creating problems.
Use a flat block to ensure pressure is even.
