Bill Parsons Posted October 19, 2016 Report Posted October 19, 2016 The grease in my pull-type emergency brake has solidified, disabling the ratcheting mechanism. I would like to take it off, clean it up, and regrease it. Is there a way to pull the rod out of the tube without removing the whole fixture from under the dash? There is a pin in the rod that moves in a slot, disallowing the removal of the rod from the tube. The pin doesn't seem to be removable either. Quote
JBNeal Posted October 19, 2016 Report Posted October 19, 2016 Maybe pulling the handle out and applying Marvel Mystery Oil to the shaft, then let sit for a days and repeat a few times, might free things up...I had the thumb button get stuck on the '49 floor lever and tried this approach... within a week, it was working fine, and no disassembly was required 1 Quote

I had to use a screwdriver to chisel out what i could reach. Also, the grooved rod doesn't pull out far enough to get to all the grooves. Quote
JBNeal Posted October 19, 2016 Report Posted October 19, 2016 MMO can soften grease to make it lubricate again, I have used it many times to free up frozen lock cylinders, ratcheting mechanism, sheaves...it takes several days of applying MMO and letting it soak in, applying some force to get the parts moving a little, reapplying MMO working the parts some more and waiting, then repeating...it took many years for these things to freeze up, it can take several days to get them to function properly...MMO and patience goes a long way Quote
Los_Control Posted October 19, 2016 Report Posted October 19, 2016 Might also be a good use for wd40, as a cleaner and not a oil. Quote

Dave72dt Posted October 21, 2016 Report Posted October 21, 2016 Try using a heat gun or sneaking a hair dryer out to the garage first, no actual flames involved then unless softened grease drips into the heat gun. 1 Quote
