Parking brake operation: pre-2018 MOT
This is pre-2018 MOT wording. The defect categories changed on 20 May 2018.
Partly now called Parking brake performance (Decelerometer). The rest has no direct match.
3 pre-2018 fail items.
| Old wording | Inspection manual | Now |
|---|---|---|
| Parking brake operation grabbing severely | for vehicles with a single line service brake system, there is no gradual variation in braking effort (grabbing). | No direct match |
| Parking brake operation is causing the vehicle to swerve to the offside | when the parking brake is applied the vehicle deviates excessively from a straight line. | Parking brake performance is causing the vehicle to swerve to the nearside (major) |
| Parking brake operation is causing the vehicle to swerve to the nearside | when the parking brake is applied the vehicle deviates excessively from a straight line. | Parking brake performance is causing the vehicle to swerve to the nearside (major) |
Current names are the closest match by wording and part. The DVSA publishes no official old-to-new table.
