If during the accident, the suspension links failed, the brake line isn't strong enough to keep the wheel/brake/hub/knuckle/strut attached to the car. While the flexible brake line is stronger than in years past, it's not designed to withstand those tension forces.
This is an unfortunate event but there isn't really a reason to try to speculate what happened since we don't have any data about the incident. Let Sam, the insurance, and GM dive into the data and conclude what happened. I am sure that if Sam feels there is a safety issue he would inform us.

Given he totaled the car, hit another car, and likely is in legal discussions, this could take months at best. And depending how such discussions conclude and on what terms, he may, or may not be able to comment publicly any further. Bottom line, he clearly indicated his pedal went to the floor with no prior warning. That's a catastrophic failure of some, yet tbd cause and hence a safety issue. In my book anyway. |

Could be he hit something on the track and didn't see it, maybe it wasn't the car at all, at this point it's all speculation, point is wear good safety equipment, the life you save may be your own.

Just curious what does ice mode do to the brakes?

https://www.camaro6.com/forums/showthread.php?t=459802 The issues in that thread are very different than the situation in question for this thread. Also, if there are issue with the power vacuum brake system, either vacuum pump, vacuum booster or sensor, it shouldn't reduce brake system pressure or effort to ZERO. The power brake system can only reduce pedal effort. It can only effect brake force indirectly through pedal force, but as long as someone is pressing the pedal, the mechanicals are connected and the hydraulic system is intact/sealed, there will not be a result of ZERO brake force - there will be something and enough to get the vehicle to a stop, although possibly at a reduced rate. >If vacuum is faulted to none, you get a hard pedal and brake force should still be available. >If vacuum is faulted to something/more than necessary, you get either a "normal" pedal or lightened pedal and brake force should still be available. In order to have ZERO brake force, the pedal with no resistance, and dropping straight to the floor, you'd have to have at least one of the following: -leaking/internally-bypassing master cylinder -leaking brake line(s) -leaking brake caliper(s) -disconnected/broken brake pedal -disconnected/broken brake pedal piston rod -disconnected/broken mounting to the master cylinder/brake booster Does anyone know if a HCU is possible of fully dumping/blocking brake force to all wheels and could it result in ZERO pedal [pressure]/the pedal dropping to the floor? I think the answer is "NO", as a fail-safe fault and that the accumulators aren't sized to allow that (not big enough to dump that amount of fluid into). |

BUT, i can't think of another word to describe the actual event other then a safety issue. Whatever the cause. As a matter of fact Id say zero brakes would be an ultimate safety issue especially at a track. Ford has just recalled all turbo F150s for brake issues and will be replacing all master cylinders and brake boosters. Dont know how many owners had to report issues before that happened. The problem is, IF this is a bad batch related (for example ONLY), it may take a few of such cases for any type of a recall. Sam was incredibly lucky not to end up 6 feet under. That's why i started this thread to: 1. See if there were any other folks that have experienced a similar problem and if so to hopefully get more info from them. 2. Give our community an oppprtunity to share views on what potentially could have caused a complete loss of brakes. Perhaps so we could check some components proactively. Or pay attention to something that we may not (like some folks hanging calipers off of brake lines, or not checking for rodent damage, etc). 3. This is not intended to cast blame on GM, or Sam, but to have a productive discussion and hopefully learn something. Cheers! |

Also, was not the car involved a used car as well? Can't remember for sure , but that would muddy the waters further.

In the terms of an OEM, it would just be labeled as an 'Event' that raised a 'Concern' with whatever rating system they use. My last employer used P1-5 with P1 being critical and P5 being the lowest. If this is the only known event, it would start out as a P5 or P4 because it is a singular event that took place under very specific and special conditions.
