Re: Reverse Brake Lockout Solenoid
The way I do it is to attack a foot of clear aquarium airline to the bleeder fitting on the brake farthest from the master cylinder.
The other end goes into a clear jar.
Open the fitting and pump the master cylinder with a screwdriver until the fluid coming out has no more bubbles.
Keep refilling the master cylinder whenever it gets half way empty or you will pump air and have to start over again. (Maybe every 10 pumps.)
Repeat for the closer side.
This is something you should learn to do yourself.
A quart of brake fluid is less than $10.
Do it yourself for less than $5. Or pay someone $100 to do it for you
This is definitely not rocket science.
If the fluid hasn't been changed for the life of the trailer, it is time to do it in any event.
Brake fluid doesn't last forever.
And DO NOT attempt to save the Fluid that ended up in the Jar!
