OEMTOOLS 24443 Brake Service/Universal Fluid Dispensing Bottle, 1 Pack

Unique dispensing design uses gravity to automatically refill the master cylinder during vacuum or manual hydraulic brake or clutch bleeding and flushing. Reservoir mounts on top of the master cylinder and clamps securely to the wall. As old brake fluid is bled from the hydraulic system through the bleed screws, new fluid flows automatically from the reservoir to replenish the master cylinder.
Capacity: 50 Oz
Mounts Securely to Master Cylinder and Clamps for Security
Universal Design Fits Most Master Cylinders and is Used to Prevent Spills
Provides a quicker method to bleed brakes without having to continuously refill the reservoir
