Brake Lesson

leave a comment »

It was another one of those days when I started with one thing in mind, and quickly ended up with a whole new project demanding attention. Starting with a goal of filling another low spot by using old hay bales that have some mold and the composted manure and bedding from the barn, we were going to use the Grizzly ATV.

Before using the Griz, I needed to remove the plow blade and change the tires to the less aggressive summer tread. I pushed the button to extend the cable so I could disconnect it from the plow, but nothing happened.

Hmm. It worked last time I used it, …about 2 months ago. Oh well, that was easy to work around. Next, I jacked up the Grizzly and removed the front tires. That’s when I noticed one of the brakes wouldn’t release. I have never done any work with disc brakes. The only things I know about brakes are the words, caliper, brake pad, and brake fluid.

I called George for advice. At dinner on Thursday, he described the work he was doing on a tractor he recently bought, which reflected just the kind of skills my new problem needed. With him giving me the confidence to start removing bolts, we started analyzing the situation.

DSCN4638eThere is definitely a problem with the right brake not releasing. Unfortunately, there is also a problem with the caliper slider pins being seized in place. The left side wasn’t much better, but at least we were able to get the pins out. That revealed the pads were definitely in need of replacement.

With George’s help, I now have a good idea of what needs to be done. All I have to do is find a way to break the corrosion bond in the right brake so I can get the dang thing apart.

Freeing corroded bolts seems to be a theme developing with this machine. If I can win that battle, this will be a chance for me to finally learn the nuances of working on hydraulic disc brakes.
