Accident caused by parking brake engaging in error

Scorpion2020 · Nov 19, 2022

A friend had a serious accident when driving at 60mph on a straight road in her Discovery 3 when the parking brake engaged full on without any driver input.

The car slewed round 90degrees and an oncoming vehicle narrowly avoided her, ending in a ditch. She broke a leg against the underside of the dashboard.

Has anyone else any experience of this type of failure? On another road it could have caused a multi car accident.

Cheers.

^ not a scenario I have come across in 13 years of Recovery work

You can apply them whilst driving and Iirc they put on the handbrake AND the main brakes, only tried mine at slow speed worked well.

Hi and welcome
I'm surprised the parking brake was able to lock up driven wheels sufficiently to cause a loss of traction

Could have been handbrake brake shoe retaining clips failed and locked up.

Most likely scenario....
...have had the pin on a retainer clip fail as a result of corrosion on the flared side of the drum backing plate on a work pick up truck. Fortunately was at slow speed, heard a groaning sound and a bit of drag as soon as I would lift off the accelerator. I reckon speed being high enough, it would inadvertently lock up one wheel, forcing the vehicle to spin around as is reported to have happened.
