Review on 🔩 Russell 639590 Speed Bleeder Valve by Christopher Bates

I rebuilt the entire drum brake system on my 1970 Ford F100 including new wheel brake cylinders, master cylinder, fixed lines and hoses. I bled the brakes for hours and they were still soft (and yes I bled the new master cylinder on the bench). In the end I couldn't stand it and ordered two sets of these to replace the bleeders on the Dorman wheel cylinders. After about 30 minutes we bled the brakes and started working like new.
