Surge brake

[kenny nunez]

I always check the fluid and replace it periodically since brake fluid tends to absorb moisture. One day one of the brake drums started smoking so I stopped and bled off the fluid. After getting home I pulled the drums and every thing looked good. I stated actuating the master cylinder and the brakes would not retract. Turned out that the orifice in the brass fitting on the master cylinder had a piece of something in it. I guess the hole is small to delay the fluid transfer and for backing up. After drilling the hole to 1/8” no more problems and just put a pin in the coupler so I could back up.

And if you have drum brakes I like to grease the adjuster threads with Evinrude triple guard grease and the same on the pivot points for the shoes. In addition there is a new design wheel cylinder being made by UPF. These are a bootless design that can’t trap water like the boot style. The boot style I have been able to make last longer by greasing the piston and filling the boot with grease. Then seal the boot to the cylinder with high temp RTV

Does it matter what dot?

Generally I’d use dot3 for an existing system it may say in the manufacturers requirements or on the master cylinder in the coupler

Note that by drilling out the damping orifice, you may experience more abrupt braking and clunking. It will likely be acceptable, but it won't be as smooth applying and releasing the brakes as it used to be.

This is called a hijack and an old thread to boot.
