Reversing the Matco Parking Brake

Posted on June 27, 2011June 26, 2012 by Jared Yates

Our spinner came with it’s original white paint, which matched the Husky that it came off of. I knew that we were going to have to repaint it one way or another, but we’ve both always preferred to have a polished spinner. I figured that I didn’t have anything to lose by stripping off the original paint and trying to polish the underlying aluminum. The chemical stripper that I used took the white paint right off, but the green primer didn’t respond to it. I used a fine scotch brite wheel in the die grinder to remove some of the green primer.

I wrote before about my reversed parking brake control problem. These pictures show the solution. I removed the spring clip on the end of the valve arm and pulled it out. I stuck it in the other way around, thus inverting the valve’s operation. This makes so much more sense! In the picture below I left the old lines and it is even more obvious. I’m also glad to have a bit more clearance between the aluminum line and the grounding tabs.
