Help with r'moving brake hose due to bolt rounded off!

[Wanabe_Garage]

Hi

Any ideas on how i can remove the brake hose from the brake line with a rounded off bolt?

[Officer Doofy]

Vice grips?

[oldeskewltoy]

try to find a 4" (100mm) long pipe wrench. Pipe wrench jaws are designed to turn round pipe... a 4" size is small enough to fit the banjo type bolt heads. The wrench I'm talking about looks like this...

vice grips for the easiest way!....after they have been rounded

if your working on brakes all day, you need to get soem good PIPE spanners...ive used cheapies/kingchrome ones and they are both shit!,

splashed out and bought some snap on ones!...they are awsum!

Vice grips are the only way.

Depending on how much room you have, get the biggest that still allow you room to move.
Grab a block of wood and use that to steady the grips.
Then tighten the crap out of it and smack it with a hammer.
You will need the impact to get the line to crack.

Good luck!

Worst comes to worst you may need to cut hard brake line with pliers, get new hard line made up as the absolute last resort. It's quite cheap to get done, you just get a brake place to make it up to the length required length and put the tube nuts and do the flares and you bend it up yourself. I have had to do this before. Sometimes they just don't want to come off!

inox or wd 40 - followed by inappropriate use of vice grips (clamp it way too tight, use wood block as noted above).

You'll munt the nut but it's a small price compared to taking car to a workshop so they can do the same thing.

Where abouts is the pipe? Can you undo the other end, break the rounded end and get another steel pipe from the wreckers?

Ive learnt not to even attempt to undo a brake line without spraying first with Inox (or WD40, both work) and some pipe spanners - even the supercrap ones are better than using a standard open ender - and dont cost much either.

I use the plumber's wrench, as suggested. Works much better than the vice grips!

I had this problem. You can use a pair of pliers (not sure of there exact name) but they are unique in that they have a knob on the bottom you twist to adjust the amount of clamping force. Get it right on and you'll have enough leverage to twist the bolt off. oh use some penetrating oil 24hrs before hand to help it.

Don't forget that it helps makes your life easier when you give tight bolts a tap on the head with a hammer before attempting to undo them. It helps loosen the static bond of the threads.

Do that before using the vice grip etc.

If you have access to an oxy torch, wack some vice grips on the nut and jently heat the female part that the nut screws into (that's a contradiction ).
This can stuff a rubber hose if you put to much heat into the metal parts but you shouldn't have to heat it up more than 120 degrees.
Try and be as fast as you can so the heat doesn't get into the nut as you are trying to expand the female piece not both piece's.
BTW buy a propper split ring spanner to help prevent this happening as they get a better grip on the nut than an open ender and it pays to stop if you think you are using excesive force and it aint undoing.

can i suggest you use a flare wrench in future to avoid rounding a brake line fitting, they are a 6 sided open spanner with a small slit in one side enough to get a brake line through

They are vicegrips dude.

Every time iv rounded off a bolt i just go buy a heavy impact 6 sided ratchet bit and hammer it on to the bolt if needed then stick the breaker bar or ratchet onto in and bobs your uncle comes straight off no probs every time.
I find the vice grips dont work very well for me if the bolt is really rounded off.
But the pipe wrench look like they would work cos there ment to get tighter the more pressure you put into them.
