Parking brake assembly managed to bind between axle and brake rotor causing catastrophic failure. right rear wheel locked up while driving very nearly causing a crash. photo is from investigation
Brake and accelerator pedal placements and operation are dangerous. the brake pedal depresses too far before engaging the brakes and is too close to the accelerator pedal to work with this braking characteristic. a boot or wide shoe can overhang the edge of the brake pedal and engage the accelerator before braking becomes effective. the engine races, you push the brake pedal harder, depressing the accelerator more, racing the engine even more... once the cycle starts you must use the emergency brake or throw it into neutral to prevent forward motion. then finally take your foot off the 'brake' -which also releases the accelerator. the brakes need to engage before they depress to the same plane as the accelerator.
