Product Description

** BACK IN STOCK FOR 1 LAST PRODUCTION RUN - DON'T MISS IT** Introduces Stainless Bleeder Screws for Audi A4, A6, and VW Passat!

This 303 Aircraft Grade Stainless Steel Bleeder Screw replaces the plastic bleeder screw which Audi and VW provide on their clutch slave cylinder P/N 8E0-721-257F (8E0721257F), 8E0-721-257M (8E0721257M), 8E0-721-257A (8E0721257A), and 8E0-721-257B (8E0721257B). 

How many times have you gone to bleed the brakes on your Audi A4, A6, VW Passat or Porsche Boxter only to round off the hex on the cheap plastic bleeder screw on your clutch slave cylinder ? Hell, try buying a BRAND NEW slave cylinder and getting that plastic bleed screw off without totally destroying it.  Im not sure ANYONE is able to bleed the slave cylinder on ANY of these vehicles with the plastic bleed screw !! 

The problem is corrosive brake fluid actually melts the cheap plastic bleeder screw and bonds it into the slave cylinder housing making it impossible to open. This problem makes it impossible to bleed your brakes properly and causes soft brake and clutch pedals. The only remedy until now has been to replace the entire slave cylinder unit, which is expensive, time consuming, and NOT FUN (to say the least!).  Not to mention, you will likely destroy even the new slave cylinder plastic bleed screw.  We say SCREW THAT, and SCREW mushy brakes and clutch pedals !! has addressed this problem with our new 303 Aircraft Grade Stainless Steel Bleeder Screws. We machine these in house on state of the art HAAS CNC lathes and mills with custom screw machining capability to exactly match the OEM threads for a perfect fit. These come complete with preinstalled Viton O-rings for maximum life. The hex will never round off or become stuck in the slave cylinder body and you likely will never need to replace a slave cylinder again.  Now, you can actually bleed the damn brakes and clutch properly !

This 303 Aircraft Grade Stainless Steel Bleeder Screw replaces the plastic bleeder screw found in the clutch slave cylinders listed below (and possibly many others) . Buy it with a new OE slave cylinder if you want, just choose from the drop down menu.
