Comments about Dorman - Help Bleeder Screws M8-1.25 x 24mm:
These were actually the wrong ones, but was fixed even before I walked out of the store. Did not get a chance to install because my extractor broke off while trying to get the old one out! GRRR!

Q:what does this do?
A:This part Dorman - Help Bleeder Screws M8-1.25 x 24mm, Part No. 13902 is a device used to create a temporary opening in an otherwise closed system, which facilitates the removal of air or another substance from the system by way of pressure and density differences. Bleed screws are at each wheel of the vehicle to allow bleeding of the braking system. Bleeding air from the brake lines is necessary for correct operation of the hydraulic system (air compresses, reducing maximum pressures) and preventing loss of braking ability. Bleeder screws generally incorporate little spring loaded ball type check valves. When you open them a half turn, they allow fluid to be pumped out but no air can come back in.
Q:do these come with a metal washer
A:These are just the brake bleeders and do not come with the metal washers.
