*Great idea!! I have a couple of spare fuel pumps (MGB which are
nominally 3-5psi) that should do the job and I may add a T and do both
wheels on one axle at a time. It may be more trouble than it's worth
as watching the MC will become even more critical. i guess I could
make a push button on/off switch with long wires so i could watch the MC
and turn the pump on and off as needed**......**

**Thanks for the suggestion --- I may try this... i keep thinking the
inlet and outlet on the FP are a lot larger than the bleeder so I may
**need a adapter ...*
Sincerely,
Larry

I cheat because it's a better, easier way to change brake fluid.
Purchase a 12 volt fuel pump, Low pressure pump that does 10 psi or less
will work fine. Purchase some clear poly tubing, the semi soft kind, that
will fit over the brake bleeder nicely. Connect that line to the 12v fuel
pump intake port, connect some more of same line to the output side of
pump. Place output hose in an empty soda bottle.
Open brake master cap. Open bleed valve [Start at the longest line]. Have
supply of fresh fluid handy. Turn on pump and watch the master cylinder
reservoir level go down. When the reservoir level gets to bottom 1/4 , add
clean fluid and pump more while watching for clean fluid to come out of
bleed port. When you get clean fluid, stop the pump and close the bleed
port. Refill the master and move to the next longest line.
Repeat for each wheel, always keeping the master reservoir with a good
supply of clean fluid.
Total time to bleed all 4 wheels and replace the total fluid with fresh is
usually less than 15 minutes.
It helps if all 4 wheels are off the ground and car in firmly on jack
stands.
As always, be safe. 12 volt, low end fuel pump online cost was less than
$25. That pump is a dedicated brake bleed pump only now. When I'm all
done, I flush the pump with mineral spirits [cheap paint thinner available
at any hardware]. Dispose of the used brake fluid properly.. save the baby
seals and the whales.. as always.

Hi Gang -
I have the stuff gathered to change my bleeder valves and R&R the
Brake fluid - well everything but the time and the brake fluid.
2 questions:
1. What DOT BF Should I use? I used to use DOT 4 but some
forums have made that sound like a poor choice.
2. How can I remove the old valves and put the new ones in
without losing lots of fluid or letting sir into the system? Some
have suggested using a short pipe to put between the seat and pedal
so the pedal is slightly depressed. does that prevent air entering
the system? Not sure I'll have the time to finish the job at one time.
Thanks Guys!
Sincerely,
Larry
