Custom Make Brake Fittings? Don't Do That! Made a 3/16 end fit a 1/4 line so that had to be fixed.

When I put the tandem brake system on the 1957 GMC the rear hard line was 1/4 but the OEM was 3/16 so the new 1/4 line didn't fit the OEM rubber hose going to the axle T fitting. To do a temp fix I drilled a 3/16 end fitting to 1/4 but that makes the fitting too weak. I got the proper brass fitting to go from 1/4 end to the 3/16 hose. I'd guess one could have gotten a rubber hose to just fit the 1/4 hard line but this is what I had and it works fine and now is OEM safe.

Please only do what I do at your own risk.

I have some information on Odysee too if you'd like to check that out and I also post these on Rumble and X.

Thank You for watching
