Just bought a couple packs (total 4) speed bleeders for the 535. Almost all BMWs are the same, Part number 639570, 7mm x 1.0

Cost on these was $6.00/each pack or $12.00 total plus $2.00 shipping. I just don't think you can buy these any cheaper.

Speed bleeders for those who do not know, make it extremely easy to bleed the brakes with one person. Very handy at the track and in the garage. Just attach your catch can, crack the bleeder 1/4 to 1/2 turn and pump the brakes a couple times. Be sure to fill the brake fluid after each wheel.

Just wanted to pass this on to the board.
