[TR] Rear Flex Hose TR3A

[TERRY SMITH]

Hello everyone.  It's been over a dozen years, so for safety will be replacing the rear brake flex hose soon.  Haven't looked at it in a long time, and haven't crawled under the car yet.  Still, it looks like the flex hose is fastened to a hard pipe leading forward, and a union box that splits off to the two rear brake cylinders.

I suppose it's necessary to undo the union box so the flex pipe can screw in without being impeded by the twisting of the rubber flex hose.  That about right?  

Thanks, everyone,
