Stubborn Brake Flex Hose Removal.

[Josie'sLandCruiser]

Hi All:

This winter I'm doing upgrades to my rig's brake system. A couple of weeks ago I installed a working brake booster and new master cylinder; currently I'm about finished with a rear disc brake swap.

Another upgrade is installing longer brake flex hoses. I attempted to remove the rear flex hose and the end that attaches to the brake hard line at the frame rail is being stubborn! I don't want to round-off the head of the brake fitting anymore then it is already, so have backed-off from using vise-grip pliers. I've soaked the fitting in Kroil penetrant; any other suggestions to un-screw this fitting without destroying it!

Thanks!

Do you have tubing wrenches in both sizes?

Have you taken the line down from the frame hanger? Usually it's easier for me to work on those when the darned clip and frame bracket aren't in my way. The it's soak, flarewrenches, and the usual try forward backward to get it to crack. Using a visegrip on the side to be replaced will be OK, if necessary.

Hi All:

Thanks "Honk" for the reply.

On the LCML "CrushersRule" suggested heating the fitting, which worked like a charm on those nearly 32 year hose fittings!

I did not want to suggest that, as I have had the hose line burst from the heat right where it is crimped.....


Glad that it worked out Alan.

Hi All:

Yeah Steve, I was a bit concerned about a fire or something!

I focused the flame on the screw-in fitting itself, didn't get too close to the crimped-on part.

Glad it worked also! Otherwise, I'd still be out there working on the rig!

On a previous car, after all other methods had failed me, I managed to get a stubborn brake line fitting loose with a small pipe wrench of all things. The flare nut wrench didn't work, the vise grips didn't work, couldn't use a torch in the confined space, but a small 8" pipe wrench cracked it loose very easily. It was able to grip the nut very easily, and actually caused less damage than the other methods. It did leave a few small serrations, but that's better than rounding off the flats. I wouldn't recommend it all the time, but as a last resort it worked for me

i got a similar problem on the diff end... the 17mm nut won't budge despite a bit of pipe slipped over the wrench.

Glad to hear that you got it, Alan.

Heat is usually my first stock answer but in this one I didn't mention it both for the reason mentioned and because I didn't know your equipment or your skill level. That's a location where heat COULD cause more damage than good results. I played it safe.

I was working on removing the brake line nuts tonight. Man what a pain!! I ended up just cutting the line because I rounded the nut off. Does any one know if a supplier that sells the complete line? Would it be just as easy to make my own?

As long as your line is under 60" and for a rig newer than 1970 [factory power brake setup] you shouldn't have any problem buying a prefab line from a local auto parts store.

'Splain this Mark. Are you talking about the Napa parts book? If so I agree it's a good source.

Better source: Brake Quip. They make hydraulic brake lines any size any length, and fitting while you wait. Cost about the same as Napa United lines too.

You can also get most of the OEM lines from $OR for pretty cheap, gotta pay an extra boxing fee and their shipping though They have most of the discontinued lines though -
