Ice Pedal --- OMG My Brakes Don’t Work
What It Is, Why It Happens and What to Do About It
by Art Meltzer
Many of us have had the awful experience of Ice Pedal (IP for short) – applying the brakes in a heavy braking zone only to find the brake pedal incompressible and the brakes barely slowing the car. This often results in going very wide around the corner, going off the track, or worse. I’ve heard various explanations of IP which suggests no one really knows what causes it.
IP is not unique to Porsche. Randy Probst describes an incident of IP on youtube while driving a yellow Mazda turbo RX-7 in 1994 at Road Atlanta. Incidentally, I’ve heard drivers of GM and Ford cars describe IP.
Bosch manufactures all Porsche brake components. I contacted Bosch inquiring about IP. All they would tell me is that IP occurs as a consequence of the ABS computer not being able to correctly analyze the wheel speed sensor data so that the computer determines there is significant wheel slip when, in fact no wheel slip is occurring.
