I’m finally able to get to installing a new master cylinder and I can’t get the fittings off the old one. I’ve tried wrenches, none fit and an adjustable wrench, which started to round the heads. Any good way of removing them so I can finally finish?

Line wrench. I’m guessing by that response that is my issue though lol.Comment

Sometimes I have had luck with vibrating the materials with hammer blows. On the master tight up against the fittings. Also use free all or the like.03 Marauder DPB, HS, 6disk, Organizer Mods> LED's in & Out, M&Z rear control arms, Oil deflector, U-Haul Trans Pan, Blue Fuzzy Dice

I tried both. 12mm is very close but didn’t work. I’ll try using a rubber mallet too.Comment

Have you tried a penetrating oil and rotating between tightening and loosening?What I Own: 1993 Mercury Grand Marquis GS

Not yet but since the threads are horizontal I don’t have too much faith in a penetrant working too well.Comment

I'd also had luck tapping the fitting with a /punch/hammer. Then with the line wrench, be quick and pull it hard and fast (think impact). Trying to go easy just rounds off the hex.1990 Country Squire - under restoration

Not the perfect situation but the oil will wick in. Worth a shot since nothing else seems to be working.Originally posted by 87GrandMarq View PostWhat I Own: 1993 Mercury Grand Marquis GS

I’ll try the punch route, maybe get a set of those wrenches too. The other issue is going to be reinstalling them afterwards. I’m sure I’ll round them off even more lol.Comment

The only reason I’m not going to heat them up is because I don’t have a torch on hand and I’m probably never going to use it again if I bought one.
Yes line wrenches but I’m going to buy a set of flare nut wrenches.Comment
