Grove gear and brake caliper question

[REDII]

I’m hoping to get some insight and advice on whether or not this is an issue. I just installed the brake line from my gun drilled Grove gear to my Matco brake calipers. It appears that the Grove gear was drilled off center and the fitting is just overlapping the front bracket of the puck housing. It appears that the puck housing is stationary and fixed to the brake plate and shouldn’t interfere with the fitting, but I’m no expert. I am not sure how I would get more clearance between the two other than mill down the puck housing bracket. Thoughts?

The caliper floats, must be free to move in/out on the guide pins.
Maybe going to -3 fittings would help.

That’s what I was thinking. When I pressed the brake, the upper part of the caliper moved but the lower caliper appeared to be impinging on the fitting.

We found that there was 2 different caliper bodies/mounts. The ones in the pics using -4 hose and fittings, are for the caliper marked PH8A. The PH1 caliper has to use -3 hoses with that hose configuration because the mounting ears are so close to the lower gear leg port. Matco told us they were the same, but something is different. With the PH1 caliper, we may have to route the hose forward and route up to the caliper. Somewhere around 14 inches. With this routing it does expose the hose to potential brake rotor heat.

Yep - the Grove gear was designed to use the old Cleaveland brakes.

This is what I did to solve the problem.

Yup, I checked and I do have the PH8 model caliper.

Thanks Carl. I’m also working with Tom to troubleshoot the problem but it looks like this is what I will be doing.

Here is the issue we're dealing with. Same PH1A caliper body number, but the lower 'ear' mounting is closer to the cener gear leg port on Carls, vs the other ones we originally designed the hoses for. Matco told us they we the same calipers, and mounting, but something obviously changed. Perhaps the mounting adapter holes are different. Anyway---it completely changes the hose and routings. YES---we'll get the solution. WE may do something similar to Carls install, maybe using a AN823-4D 45* adapter at the top and routing the hose that way. I want to keep it from being exposed to as little rotor heat as possible.
