[DML] Re: Oscillation on braking



I had the same problem and I also blamed warped rotor(s). I replaced 
them to no avail.

The cause was a couple of things actually. I bought new, but 
aftermarket calipers. They bolted up perfectly but were poorly made. 
One caliper grabbed much harder than the other. Also my flexible 
brake lines were old OEM and probably expanding under pressure.

I replaced all of my calipers with rebuilt OEM and replaced the 
flexible lines with new ones and now the braking is straight and true 
with no pulsing.

You may consider this before buying new rotors, or at least just 
check the rotors for trueness before buying replacements.
