Speed Bleeders for the RS

[Grumpy Goat]

Nice videos.  Are you going to do a follow up video on the brake bleeding process with the speed bleeders?  ...

Even though our dear friend John is no longer on this earth, I will answer his question as he'll surely hear it from on high.

The video I will be doing is the replacement of the left caliper "screw plug with ventilation" and then the reinstallation of the original BMW valves on all 3 calipers.

Today I went to do a flush of by brake fluid as part of the 60k mile service (and since the fluid had <3% moisture content). I was conscious of how frail these Speed Bleeders were so I was prepared (or so I thought). Got everything ready and set up to loosen the Speed Bleeders (even had the 3 different size box wrenches attached to the SBs). I started with the left front and pushed a good reservoir-full of fluid out after slacking off 1/4 turn. When I re-tightened the LF SB - put it back to the same angle that I started from when I loosened it - it simply sheared off. I did not overtighten it. It must have been heat-fatigued since installation (during which I did not shear it off, mind). 

   

I considered using my extractor, but the SB was so tiny that the bit that was suitable contacted the ball first and did not want to risk pushing the ball into the caliper! I understand Speed Bleeder (the company) has an "extraction service" where you have to send the caliper to them! What *^(*&$ drama! I topped back up the reservoir and aborted the system flush. At least I can still ride the bike. 

I decided to fire the lot of them - no more "plastic" Speed Bleeders for me. I ordered the screw plug with ventilation and when that comes, I will revert back to stock.

I ordered the Motion Pro inline speed bleeder Lee uses.
