hi all, from santiago of chile!
my experience.... i drive to my home in last year, with a very strong rain... and, very fast.... when brake, no brake..., (hard pedal):( (abs light)
i replace totally from cutlass supreme, rotors (front and rear) i change the frontal caliper, and adapt hand brake for rear calipers.... but...
my wheels not compatibility with news upgrades.... i put the oem wheels olds cutlass supreme 89.
Result: ver very very strong and hevy brakes! (and end of the drums problem)
the bonus: EBC 3gd rotor (front), EBC yellow stuff (front and rear), metallic hoses (anti-fading) fluid ebc to up 300 celcius
heavy duty brakes!!! in all moments, all!
