Stop It!

So the truck is now running, but the stopping part could use a little more attention. The brake pedal is precariously close to the floor before any strong pedal is felt. An inspection of the brake fluid in the master cylinder indicates that the fluid is both low and in need

of changing. I had to remove the flooring in the truck to get a decent look at the master, so I decide that a good place to start would be with replacing it.

As it turns out, the master cylinder in the later K-Series is the same as the one in the D-Series. Why is this important? Because Rock Auto carries the Raybestos MC1722 master cylinder for the K1 for a mere $114!

So a quick bench-bleed of the master, an addition of new DOT 3 brake fluid via a good long session of bleeding (Susan LOVES me yelling “Up!”, “Down!”, “Pump it up” at her… yes, she is a very good sport about these things!), some adjustments at the wheels, and the result is a nice, firm pedal.

No leaks were noted at any of the wheels, so the slave cylinders and wheel bearings will be gone over at a later date. A quick cleanup of the drums and a coating of Rust Bullet has them looking spiffy.

Back on the road in just a few hours.
