Bleeding Process 120-130

I bled the brakes using a process similar to one decribed for changing brakes in the 700/900 FAQ. I took a bottle and filled it with brake fluid, got a clear rubber tube and secured it to the bleed nipple. I then put the other end of the tube into the brakefluid bottle and pumped the brakes up. Then, opened the bleed nipple and let the fluid (and air) flow through the tube in to the fluid. I then pumped the brakes many times and watched the reservoir start to drain through the line. When the clear tube was devoid of air bubbles, I sealed the bleed nipple and moved on to the next wheel. I had to be careful not to let the reservoir drain and allow air back into the system.

This whole approach may be suspect and may be the cause of my really weak brakes. Logically, it should work fine, but this was my 1st time doing it this way. I still suspect my new seals, even though they do push fluid. A power bleeder would let me figure it out for sure.

It was messy because the rubber tube would twist when I opened/closed the bleeder nipple and tube would knock the bottle over. I put the bottle in a large coffee can and the tube woudl then flip out and splatter me with brakefluid. Pretty nasty (and poisonous) experience.
