Abstract
A portable vehicle fluid drain device is disclosed. The device includes a vertical drain tube which supports a vehicle fluid drain bowl. The drain tube is manually adjusted to an elevated position, latched in place while the vehicle fluid is drained, and unlatched to descend at a rate less than that of free fall due to the use of a friction brake. The friction force imparted by the brake on the drain tube is adjusted by rotating a wing nut on a carriage bolt to squeeze the inner edges of two wishbone arms against the drain tube. A method of using a vehicle fluid drain device with a brake and a self-latching mechanism is disclosed.
