Tom,
If you can't find the speed bleeders for your brakes, here is what I do:
1. Remove the bleeder valves and wrap the threads with three turns of teflon tape, leaving the first thread uncovered by the tape (bare).
2. Screw the valves back into the cylinder.
3. Slip a piece of tubing (3/16" fit my valves) over one of the valve tips and insert the other end of the tubing in a bottle that has 1/2" of brake fluid in the bottom. Make sure that the tubing end is covered by the brake fluid.
4. Loosen the valve just enough for the old brake fluid to exit under light pressure.
5. Go to the cab and slowly pump the brakes. Keep an eye on the fluid level in the master cylinder, and refill as needed.
6. When you have pumped enough fluid through the system, close the valve and move to the next wheel.
The teflon tape keeps air from leaking into the system when the brake pedal is released, and it helps keep the valves from from getting stuck by rust.
