Re: Shinn Brake Backing Covers

Try looking at Luscombe as they used shinn too but they had a different axle of the 1.25 in diameter also there cable was different

I measured the center hole on the assemblies in question and they are 1.5. I tried placing it on one of my gear legs and the bolt pattern was the same but was sloppy because of the bigger center hole . You can see in the picture that the green assembly has a hole cut open at the top. I think that was done so it would have clearance to fit on the gear leg. Plus it was pointed out to me that the dowel was missing. I also think that was done so it would fit on the taylorcraft gear leg. Thanks to all of you for your help. You guys were right, they are not taylorcraft brake assemblies. They were just altered to fit a taylorcraft. Now I will have to figure out the correct application. I will check out the to see if they are Luscombe assemblies. Again thanks to you all for your help!

They are PT-22 brakes

Long way from a Taylorcraft! Thank You!

PT22 brakes are hydraulic are they not? I started to mention PT, but was fairly certain they were hydraulic

The ones on my friend's PT are hydraulic.

Re: Shinn Brake Backing Covers

PT-22 brakes are hydraulic, but they're the same size as the mechanical ones, with almost exactly the same components, and all they did was change the angle on the feet of the horseshoe part so that they could push the top with a brake cylinder instead of pulling it with a cable. The "twisting" of the ends will still push the shoes apart and against the drum (the large holes cut in the backing plates in the previous photos are probably to try to get more movement on the horseshoe because they didn't change the angle of the feet). And the backing plates are attached permanently to the shoe mounting bracket, as in the photos. I had a thread on here some time ago about converting PT-22 brakes back to mechanical actuation. Also the PT-22 uses the lining on the shoes instead of the drum, and the wheels look very similar to the older ones but are rated for something like 1,080 lbs. each.

So what would be the application for these assemblies? Would or could they still be used on a PT-22? I have a complete set and a set with no shoes, springs etc. Thanks.
