Wot-Nots Brake Bleed Tube Automatic (PWN189)

Description

Genuine Wot-Nots · Part no. PWN189

The Wot-Nots Brake Bleed Tube Automatic (PWN189) is a soft rubber tube that pushes onto a caliper or wheel cylinder bleed nipple and carries old fluid and air out into a jar. The split at its far end works as a simple one-way valve when kept under the fluid, so one person can bleed the brakes alone.

Good to know

• How do I use it on my own? Push the tube onto the nipple, sit the split end under some clean fluid in a jar, open the nipple a little and pump the pedal; the split lets fluid out but stops air being sucked back in.
• What must I watch while bleeding? Keep the reservoir topped up so it never drops low enough to draw in air, follow the bleeding order in the workshop manual or handbook and top up only with the fluid grade printed on the reservoir cap.
• Is there anything it can't do? Cars with ABS sometimes need the pump bled with a diagnostic tool, and a pedal that stays soft after bleeding points to a fault elsewhere; brake fluid also strips paint, so wipe up any drips straight away.

Which one?

To scrub dirt off the caliper before you open the nipple, use the Workshop Warehouse Parts Cleaning Brush (TNH266C).
