Brake Caliper Bleeder Valve, M8 - Many BMW Applications

This part is listed by BMW as BMW part number 34116758107 (34-11-1-6-758-107) and is described as Brakes Ventilation Valve with M8x1.25 threads, a 9mm hex, and made by Ate, an original equipment (OE) manufacturer for BMW. 

This screw-in valve is designed for bleeding your brake fluid to assure there are no air bubbles in your brake fluid. It screws into the respective brake caliper, and it is common for these to get stripped or broken and need to be replaced. 

This bleeder valve is used on many BMW models and many BMW brake calipers from about 1992 thru 2013. Please check your existing bleeder to be sure this is the type used in your brake caliper. This part uses a 9mm hex head but it's possible you have a smaller bleed screw.
